Please use the TLC STANDARD RULES when participating in this challenge.

                                      

1. “Hundred” doesn’t mean 100.
The word “hundred” is actually derived from the Old Norse word hundrath, which means “long hundred,” and equals 120, not 100. Good luck trying to argue that your $100 bill is worth 20 percent more than it is.
🔢 Read a book that has 100-120 pages, with a character over 100 years old, or spell out HUNDRED.

2. There is only one even prime number.
The number 2 is the smallest and first prime number (since all other even numbers are divisible by two).
🔢 Read the second book in a series, a book where the page count is divisible by 2, or spell out TWO.

3. The square root of two is called “Pythagoras’ Constant.”
Remember the Pythagorean Theorem? Well, Pythagoras’ Constant is the square root of 2 (1.41). It’s also the first irrational number (a real number that cannot be written as a simple fraction) discovered.
🔢 Read a book where the main character has a theory, with an irrational character, or spell out ROOT.

4. Zero is the only number not represented in Roman numerals.
Roman numerals were developed to facilitate trade by standardizing the pricing of goods and services and are represented by seven different letters: I, V, X, L, C, D, and M. There isn't a numeral for 0 because the ancient Greeks didn’t consider it a number. Aristotle had dismissed zero as a number because you couldn't divide by zero; however, they were aware of zero as a concept and used the Latin word nulla to represent the concept of zero (as in "we have no food").
🔢 Read a book with a title beginning or ending with I, V, X, L, C, D, or M, with a Greek character in the story, or spell out ROMAN.

5. Different cultures discovered zero at different times.
Indian astronomer and mathematician Brahmagupta is credited with introducing the formal concept of zero into a number system, around 600 A.D. Brahmagupta 's other contributions to mathematics and astronomy include explaining how to find the cube and cube-root of an integer. He also developed rules for the computation of squares and square roots.
🔢 Read a book with a cube (not a square) on the cover, an astronomer or mathematician character, or spell out ZERO.

6. Zero is an even number.
Mathematically, an even number is a number that can be divided by two and still create a whole number. Zero meets the criteria because if you halve zero, you get zero. Don't worry if this is confusing - in the 1990s, researchers at Cambridge University discovered people are 10% slower deciding if zero is an even number versus the other even numbers.
🔢 Read an even-numbered book in a series, a book with a character attending or working in a university, or spell out EVEN.

7. There is only one number spelled with the same number of letters as itself.
The number 4 is the only number spelled with the same number of letters as itself (f-o-u-r). Oh, and the number 4 on a calculator is made up of four light bars.
🔢 Read a book with a four-letter word in the title, with four friends or family members in the story, or spell out FOUR.

8. Take any number and multiply it by three for a cool trick.
Take any number, and multiply it by three. Then, take the digits of that new number and add them all together. Whatever number that equals will always be divisible by three, no matter what number you started with. For example:
3 x 4 = 12
1 + 2 = 3
3 / 3 = 1
🔢 Read a book where a character plays a trick on another character, where the main character creates something new out of something old, or spell out THREE.

9. Six is the smallest perfect number
In number theory, a perfect number is a positive integer that is equal to the sum of its positive divisors. By this rule, six is the smallest perfect number. If you scratched your head and said, “Huh?” here’s an example: 1 + 2 + 3 = 6. The next perfect number doesn’t occur until 28 (1 + 2 + 4 + 7 + 14 = 28). It turns out perfection really is few and far between…
🔢 Read a book where the main character finds "perfection" (your interpretation), a book you found confusing, or spell out SIX.

10. The number Pi is an irrational number.
The number Pi—also known as the ratio of the circumference to the diameter of a circle—is irrational. This is because Pi cannot be written as a fraction. Also: Pi, when written as a decimal, never repeats and never ends.
🔢 Read a book with a circle on the cover, a book you thought would never end, or spell out RATIO.

11. Two and five are the only prime numbers that end with 2 and 5.
A prime number is a natural number greater than one that cannot be created by multiplying two smaller natural numbers. In non-math speak, prime numbers are numbers greater than 1 that can only be formed by multiplying 1 by itself. A natural number greater than one that is not prime is called a composite number.
🔢 Read a book with a word in the title or where the author's first or last name begins and ends with the same letter (ex: With Silent Screams - screams) or spell out PRIME.

12. The Fibonacci Sequence appears in nature.
Leonardo Fibonacci lived in 13th-century Italy and is credited with discovering a mathematical sequence that’s now named after him: the Fibonacci Sequence. The sequence is found by adding the previous two numbers of the sequence together. It looks like this: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34... and on it goes. This pattern can be visualized as:

The Fibonacci Sequence is often seen in nature. Nautilus shells follow the progressive proportional increase of the Fibonacci Sequence as do hurricanes and tornadoes and even parts of the human face.

🔢 Read a book with only a face on the cover, where nature plays an important role in the story, or spell out NAUTILUS.

13. 9 is considered a “magic” number.
Have you ever heard that the number 9 is considered to be a “magic” number (and I always thought it was 3)? No? Well, it is, and here's why: if you multiply a number by 9 and add all the digits of the new number together, the sum will always add up to 9. For example:

8 x 9 = 72

7 + 2 = 9

OR

4 x 9 = 36

3 + 6 = 9
🔢 Read a book with magic in the story, where something in the story multiplies (your interpretation) or spell out NINE.

14. The number Pi spells the food “PIE”.
If you write Pi (to the first two decimal places of 3.14) backward, in big, blocky letters it actually reads “PIE.”

🔢 Read a book where the main character eats or makes a pie, with big or blocky letters on the cover, or spell out PI.

15. One isn't a prime number.
Many think the number 1 is a prime number, it isn't. One doesn't fulfill the requirements to be prime (being divisible by both 1 and itself). Divide 1 by 1 and you get…1. Nothing has been divided.
🔢 Read a book with a clone in the story, told from only one point of view, or spell out ONE.

16. If a pizza has radius “Z” and height “A” the equation becomes…
Since the volume of a cylinder is Pi, times the radius squared, times height, that would mean a pizza with radius “Z” and height “A” would have the volume of… PI * z * z * a.
🔢 Read a book with a "square" character, with a tall character, or spell out PIZZA.

17. 7 is the most popular “favorite number” and is arithmetically unique
If you walked up to someone on the street and asked them what their favorite number is—of all the whole numbers between 1 and 100—there’s almost a 10 percent chance they will say “7.” These were the findings of mathematician Alex Bellos, who asked respondents to identify their favorite number and discovered that 9.7% of the time their answer was “7”.

Another reason 7 may be so popular because it is arithmetically unique. Alex Bellos explains: “Of the first 10 numbers, seven is the most prime. You cannot multiply or divide it within the group. It feels unique.” For example, you could multiply 4 by 2 to get 8 or divide 10 by 2 to get 5, but there’s nothing you can do with 7.
🔢 Read a book with a unique main character, reread a favorite book, or spell out SEVEN.

18. The most popular two-digit number is 13
Alex Bellos’ also discovered that the most popular two-digit number (selected by 5 percent of all respondents), and sixth-most popular number overall (following 7, 3, 8, 4, and 5 in the top five spots—that’s right, the number five is also the fifth most popular numbers) is 13.
🔢 Read a book with a 7, 3, 8, 4, 5, or 13 in the publication day, a popular book (your interpretation), or spell out THIRTEEN.

19. Six Weeks = 10! Seconds
That is, 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 3,628,800 seconds = 60,480 minutes = 1,008 hours = 42 days = 6 weeks.
🔢 Read a book with a number or an ! in the title, a book with an equation in the story or where a character does math, or spell out TIME.

20. Googol, Googolplex, and Google
A googol is 10 to the 100th power (1 followed by 100 zeroes) and is larger than the number of elementary particles in the universe, which amount to only 10 to the 80th power. Googolplex is the term for 10 to the power of googol - that is, 1 followed by 10 to the power of 100 zeros. Larry Page and Sergey Brin, the founders of Google, named their search engine after the term googol. In 1997, Larry was brainstorming names with other Stanford graduate students, including Sean Anderson, and looking at available domain names. Anderson miskeyed googol as "google" and found it available. Larry liked it and the name "Google" stuck. Google's corporate headquarters is called the GooglePlex, an affectionately tongue-in-cheek reference to the origins of the company name.
🔢 Read a book where the main character uses the internet, with a large number of characters, or spell out GOOGOL (or GOOGLE).

21. The Mile-High City is exactly one mile high.
The city of Denver, Colorado, has an elevation of precisely 5,280 feet—that’s the length of a mile—which is why Denver is called the “mile high” city.
🔢 Read a book that takes place in Denver or Colorado, with the words mile and high in the story, or spell out MILE.

22. In Asia, 4 is considered unlucky.
Also known as “tetraphobia” the number 4 is viewed with superstition and distrust in much of East Asia because the word for “four” sounds similar to “death” in many Asian languages, including Chinese, Japanese, and Korean.
🔢 Read a book with an unlucky character, a character with a phobia, where someone dies, or spell out ASIA.

23. In Thailand, “555” is hilarious
Teenagers texting in Thailand will send the digits “555exclu” to indicate that something is funny. The reason? Five is pronounced “ha”—so “555” translates to “hahaha.” Thus, “55555” means “hahahahaha,” or “ha” squared.
🔢 Read a book with a text message in the story, where the main character frequently laughs, or spell out FIVE.

24. (6 × 9) + (6 + 9) = 69
Don’t laugh. Just type that into your calculator and you’ll see it’s true.
🔢 Read a book with a main page genre of romance or erotica, where a character discovers the truth, or spell out SIXTY-NINE.

25. There are 31 days in most months.
Out of the twelve months that make up a calendar year, the majority of these have 31 days: January, March, May, July, August, October, and December. Only four months—April, June, September, and November—have 30 days. And, of course, February typically only has 28 days, except for leap years, when the month jumps up to 29 days—which happens every four years. The next leap year is 2020. You will know if a year is a leap year when the year’s number is evenly divisible by four.
🔢 Read a book published on the 28th, 29th, 30th, or 31st of a month, read a book published in 2020 or spell out MONTH.

26. In a group of 23 people, two will probably share a birthday.
In a room with 23 people, there is a 50% chance that two will share the same birthday. The odds increase to 99.9% in a group of 70 people. This phenomenon is called the birthday problem or birthday paradox. The statistical calculation for why this is gave me a headache, so here is a lovely graph showing the results.

🔢 Read a book with a chart, graph, map or other illustration/picture in the book, where a character has a birthday, or spell out BIRTHDAY.

27. We see odd numbers as male, even numbers as female.
You wouldn’t think numbers could have genders, but in our weird brains, they do. Research published in the Journal of Experimental Psychology found that when an odd number was paired with a baby, subjects were much more likely to believe the baby was male, while they would assume the baby was female when paired with an even number.

According to Live Science: “Our tendency to assign gender to numbers has a long history. Both the Pythagorean philosophy of ancient Greece and the Chinese philosophy of yin and yang viewed numbers as possessing gender. Both cultures also viewed odd numbers as masculine and even numbers as feminine.”
🔢 Read a book tagged psychology or science, with an alpha male or girly-girl main character, or spell out ODD.

28. There are more ways to arrange a deck of cards than there are atoms on earth.
If you shuffle a deck of cards, chances are that exact order has never existed before in the history of the universe. Cassandra Lee at McGill University broke it down: “There are somewhere in the range of 8 x 1,067 ways to sort a deck of cards. That’s an 8 followed by 67 zeros. To put that in perspective, even if someone could rearrange a deck of cards every second of the universe’s total existence, the universe would end before they would get even one-billionth of the way to finding a repeat.”
🔢 Read a book with playing cards in the story, a book that takes place in a different universe or on another world, or spell out CARDS.

29. 111,111,111 × 111,111,111 = 12,345,678,987,654,321
Though good luck finding a calculator that can factor equations in the millions.
🔢 Read a book with all the same numbers in the page count (111, 222) or a book with the numbers in sequence in the page count (234, 432) or spell out MILLION.

30. -40 is the only temperature that is the same in both Fahrenheit and Celsius
Negative 40 degrees, or “40 below,” is the only temperature that is the same in both Fahrenheit and Celsius. Other fun facts about the number 40: there are 40 standard spaces on a Monopoly board, the standard American workweek is 40 hours, and 40 is the maximum number of players an MLB team can sign on its roster at one time. Oh, and a typical pregnancy lasts 40 weeks.
🔢 Read a book that takes place in a cold climate, where two cultures or people find commonality or spell out FORTY.

You wouldn’t think numbers could have genders, but in our weird brains, they do. Research published in the Journal of Experimental Psychology found that when an odd number was paired with a baby, subjects were much more likely to believe the baby was male, while they would assume the baby was female when paired with an even number.Our tendency to assign gender to numbers has a long history. Both the Pythagorean philosophy of ancient Greece and the Chinese philosophy of yin and yang viewed numbers as possessing gender. Both cultures also viewed odd numbers as masculine and even numbers as feminine.
🔢 Read a book with an alpha male or girly-girl main character.

✔ There are more ways to arrange a deck of cards than there are atoms on earth.
If you shuffle a deck of cards, chances are that exact order has never existed before in the history of the universe. Cassandra Lee at McGill University broke it down: “There are somewhere in the range of 8 x 1,067 ways to sort a deck of cards. That’s an 8 followed by 67 zeros. To put that in perspective, even if someone could rearrange a deck of cards every second of the universe’s total existence, the universe would end before they would get even one-billionth of the way to finding a repeat.”

Since the volume of a cylinder is Pi, times the radius squared, times height, that would mean a pizza with radius “Z” and height “A” would have the volume of… PI * z * z * a.
Read a book with a tall character Kind 44=Child 44 by Tom Rob Smith 5* 12/4 - MMC was very tall

✓ 17. 7 is the most popular “favorite number” and is arithmetically unique
If you walked up to someone on the street and asked them what their favorite number is—of all the whole numbers between 1 and 100—there’s almost a 10 percent chance they will say “7.” These were the findings of mathematician Alex Bellos, who asked respondents to identify their favorite number and discovered that 9.7% of the time their answer was “7”.
Another reason 7 may be so popular because it is arithmetically unique. Alex Bellos explains: “Of the first 10 numbers, seven is the most prime. You cannot multiply or divide it within the group. It feels unique.” For example, you could multiply 4 by 2 to get 8 or divide 10 by 2 to get 5, but there’s nothing you can do with 7.
Read a book with a unique main character, reread a favorite book. Swamp Team 3 by by Jana Deleon 5* 1/10 - a CIA assassin posing as librarian/beauty queen is unique for me and this book comes from my most favorite series and is a 2nd or 3rd re-read

✓ 18. The most popular two-digit number is 13
Alex Bellos’ also discovered that the most popular two-digit number (selected by 5 percent of all respondents), and sixth-most popular number overall (following 7, 3, 8, 4, and 5 in the top five spots—that’s right, the number five is also the fifth most popular numbers) is 13.

✓ 19. Six Weeks = 10! Seconds
That is, 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 3,628,800 seconds = 60,480 minutes = 1,008 hours = 42 days = 6 weeks.

✓ 20. Googol, Googolplex, and Google
A googol is 10 to the 100th power (1 followed by 100 zeroes) and is larger than the number of elementary particles in the universe, which amount to only 10 to the 80th power. Googolplex is the term for 10 to the power of googol - that is, 1 followed by 10 to the power of 100 zeros. Larry Page and Sergey Brin, the founders of Google, named their search engine after the term googol. In 1997, Larry was brainstorming names with other Stanford graduate students, including Sean Anderson, and looking at available domain names. Anderson miskeyed googol as "google" and found it available. Larry liked it and the name "Google" stuck. Google's corporate headquarters is called the GooglePlex, an affectionately tongue-in-cheek reference to the origins of the company name.

✓ 22. In Asia, 4 is considered unlucky.
Also known as “tetraphobia” the number 4 is viewed with superstition and distrust in much of East Asia because the word for “four” sounds similar to “death” in many Asian languages, including Chinese, Japanese, and Korean.

✓ 23. In Thailand, “555” is hilarious
Teenagers texting in Thailand will send the digits “555exclu” to indicate that something is funny. The reason? Five is pronounced “ha”—so “555” translates to “hahaha.” Thus, “55555” means “hahahahaha,” or “ha” squared. my favorite and learned something new again :-)
Read a book where the main character frequently laughs. Cindy and the Prince by Debbie Macomber 2* 12/21 - Cindy (especially in the first half of the book)

✓ 25. There are 31 days in most months.
Out of the twelve months that make up a calendar year, the majority of these have 31 days: January, March, May, July, August, October, and December. Only four months—April, June, September, and November—have 30 days. And, of course, February typically only has 28 days, except for leap years, when the month jumps up to 29 days—which happens every four years. The next leap year is 2020. You will know if a year is a leap year when the year’s number is evenly divisible by four.
Read a book published on the 28th, 29th, 30th, or 31st of a month. Twas The Night Before Christmas: A Visit from St. Nicholas by Clement C. Moore 3* 12/8 - this edition was published 3/30/11

✓ 26. In a group of 23 people, two will probably share a birthday.
In a room with 23 people, there is a 50% chance that two will share the same birthday. The odds increase to 99.9% in a group of 70 people. This phenomenon is called the birthday problem or birthday paradox. The statistical calculation for why this is gave me a headache, so here is a lovely graph showing the results.

✓ 27. We see odd numbers as male, even numbers as female.
You wouldn’t think numbers could have genders, but in our weird brains, they do. Research published in the Journal of Experimental Psychology found that when an odd number was paired with a baby, subjects were much more likely to believe the baby was male, while they would assume the baby was female when paired with an even number.
According to Live Science: “Our tendency to assign gender to numbers has a long history. Both the Pythagorean philosophy of ancient Greece and the Chinese philosophy of yin and yang viewed numbers as possessing gender. Both cultures also viewed odd numbers as masculine and even numbers as feminine.”
Read a book with an alpha male or girly-girl main character. Zum Tod verführt=Thankless in Death by J.D. Robb 4* 12/11 - Roarke (an alpha male)

✓ 28. There are more ways to arrange a deck of cards than there are atoms on earth.
If you shuffle a deck of cards, chances are that exact order has never existed before in the history of the universe. Cassandra Lee at McGill University broke it down: “There are somewhere in the range of 8 x 1,067 ways to sort a deck of cards. That’s an 8 followed by 67 zeros. To put that in perspective, even if someone could rearrange a deck of cards every second of the universe’s total existence, the universe would end before they would get even one-billionth of the way to finding a repeat.”
Read a book that takes place in a different universe or on another world. Wonderment In Death by J.D. Robb 4* 12/21 - takes partially place in Wonderland and the afterlife

✓ 29. 111,111,111 × 111,111,111 = 12,345,678,987,654,321
Though good luck finding a calculator that can factor equations in the millions.

Other fun facts about the number 40: there are 40 standard spaces on a Monopoly board, the standard American workweek is 40 hours, and 40 is the maximum number of players an MLB team can sign on its roster at one time. Oh, and a typical pregnancy lasts 40 weeks.

Duration: December 1, 2019 - November 30, 2020

Levels
Intermediate: 15-20 tasks
Advanced Placement: 25-30 tasks

Completed: 23

1. “Hundred” doesn’t mean 100.
The word “hundred” is actually derived from the Old Norse word hundrath, which means “long hundred,” and equals 120, not 100. Good luck trying to argue that your $100 bill is worth 20 percent more than it is.
🔢 Read a book that has 100-120 pages,
Dragon to the Rescue, Terry Bolryder, 05.12.2019 - 179 pages

2. There is only one even prime number.
The number 2 is the smallest and first prime number (since all other even numbers are divisible by two).
🔢 Read a book where the page count is divisible by 2
Echo Killer, Christi Daugherty, 05.12.2019 - 444 pages

3. The square root of two is called “Pythagoras’ Constant.”
Remember the Pythagorean Theorem? Well, Pythagoras’ Constant is the square root of 2 (1.41). It’s also the first irrational number (a real number that cannot be written as a simple fraction) discovered.
🔢 Read a book where the main character has a theory
Waistcoats & Weaponry, Gail Carriger, 24.03.2020

4. Zero is the only number not represented in Roman numerals.
Roman numerals were developed to facilitate trade by standardizing the pricing of goods and services and are represented by seven different letters: I, V, X, L, C, D, and M. There isn't a numeral for 0 because the ancient Greeks didn’t consider it a number. Aristotle had dismissed zero as a number because you couldn't divide by zero; however, they were aware of zero as a concept and used the Latin word nulla to represent the concept of zero (as in "we have no food").
🔢 Read a book with a title beginning or ending with I, V, X, L, C, D, or M
The Bridge Over the River Kwai, Pierre Boulle, 15.12.2019

5. Different cultures discovered zero at different times.
Indian astronomer and mathematician Brahmagupta is credited with introducing the formal concept of zero into a number system, around 600 A.D. Brahmagupta 's other contributions to mathematics and astronomy include explaining how to find the cube and cube-root of an integer. He also developed rules for the computation of squares and square roots.
🔢 Read a book with an astronomer or mathematician character
Unlocked, Courtney Milan, 13.01.2020

6. Zero is an even number.
Mathematically, an even number is a number that can be divided by two and still create a whole number. Zero meets the criteria because if you halve zero, you get zero. Don't worry if this is confusing - in the 1990s, researchers at Cambridge University discovered people are 10% slower deciding if zero is an even number versus the other even numbers.
🔢 Read a book with a character attending or working in a university
Ninth House, Leigh Bardugo, 07.12.2019

7. There is only one number spelled with the same number of letters as itself.
The number 4 is the only number spelled with the same number of letters as itself (f-o-u-r). Oh, and the number 4 on a calculator is made up of four light bars.
🔢 Read a book with a four-letter word in the title,
Just Like Heaven, Julia Quinn, 09.12.2019

8. Take any number and multiply it by three for a cool trick.
Take any number, and multiply it by three. Then, take the digits of that new number and add them all together. Whatever number that equals will always be divisible by three, no matter what number you started with. For example:
3 x 4 = 12
1 + 2 = 3
3 / 3 = 1
🔢 Read a book where a character plays a trick on another character, where the main character creates something new out of something old, or spell out THREE.

9. Six is the smallest perfect number
In number theory, a perfect number is a positive integer that is equal to the sum of its positive divisors. By this rule, six is the smallest perfect number. If you scratched your head and said, “Huh?” here’s an example: 1 + 2 + 3 = 6. The next perfect number doesn’t occur until 28 (1 + 2 + 4 + 7 + 14 = 28). It turns out perfection really is few and far between…
🔢 Read a book you found confusing
Terrier, Tamora Pierce, 30.03.2020

10. The number Pi is an irrational number.
The number Pi—also known as the ratio of the circumference to the diameter of a circle—is irrational. This is because Pi cannot be written as a fraction. Also: Pi, when written as a decimal, never repeats and never ends.
🔢 Read a book with a circle on the cover, a book you thought would never end, or spell out RATIO.

11. Two and five are the only prime numbers that end with 2 and 5.
A prime number is a natural number greater than one that cannot be created by multiplying two smaller natural numbers. In non-math speak, prime numbers are numbers greater than 1 that can only be formed by multiplying 1 by itself. A natural number greater than one that is not prime is called a composite number.
🔢 Read a book with a word in the title or where the author's first or last name begins and ends with the same letter
Sea of Shadows, Kelley Armstrong, 16.12.2019

12. The Fibonacci Sequence appears in nature.
Leonardo Fibonacci lived in 13th-century Italy and is credited with discovering a mathematical sequence that’s now named after him: the Fibonacci Sequence. The sequence is found by adding the previous two numbers of the sequence together. It looks like this: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34... and on it goes. This pattern can be visualized as:

The Fibonacci Sequence is often seen in nature. Nautilus shells follow the progressive proportional increase of the Fibonacci Sequence as do hurricanes and tornadoes and even parts of the human face.

🔢 Read a book with only a face on the cover, where nature plays an important role in the story, or spell out NAUTILUS.

13. 9 is considered a “magic” number.
Have you ever heard that the number 9 is considered to be a “magic” number (and I always thought it was 3)? No? Well, it is, and here's why: if you multiply a number by 9 and add all the digits of the new number together, the sum will always add up to 9. For example:

8 x 9 = 72

7 + 2 = 9

OR

4 x 9 = 36

3 + 6 = 9
🔢 Read a book with magic in the story
Minions and Magic, Debra Dunbar, 23.12.2019

14. The number Pi spells the food “PIE”.
If you write Pi (to the first two decimal places of 3.14) backward, in big, blocky letters it actually reads “PIE.”

🔢 Read a book where the main character eats or makes a pie
Strawberry Shortcake Murder, Joanne Fluke, 16.02.2020

15. One isn't a prime number.
Many think the number 1 is a prime number, it isn't. One doesn't fulfill the requirements to be prime (being divisible by both 1 and itself). Divide 1 by 1 and you get…1. Nothing has been divided.
🔢 Read a book told from only one point of view
The Alchemist and an Amaretto, Annette Marie, 15.02.2020

16. If a pizza has radius “Z” and height “A” the equation becomes…
🔢 Read a book with a tall character
The Diviners, Libba Bray, 28.05.2020

17. 7 is the most popular “favorite number” and is arithmetically unique
