  Welcome to Kit Cast Daily, where we bring news, trivia, fun
• 0:37
  facts, and more just for curious kids like you.

  Today, get ready for something wild and exciting because we're
• 0:45
  diving into the world of crazy math facts.
• 0:48
  That's right, math isn't just about homework and tests.
• 0:52
  It's also full of surprising, funny, and mind blowing facts
• 0:55
  that can make you say, wow, I didn't know that.
• 0:59
  Whether you already love math or you think it's a little tricky,
• 1:02
  you're about to discover just how weird and wonderful numbers
• 1:05
  can be. Let's start with something that
• 1:07
  might surprise you. Did you know that 0 wasn't
• 1:10
  always a part of math? That's right.
• 1:13
  For a long time, people did math without the #0 Ancient Egyptians
• 1:18
  and Romans didn't use zero in their number systems.
• 1:21
  It wasn't until around the year 600 that a mathematician from
• 1:25
  India started using 0 as a number.
• 1:28
  Now we use 0 all the time, whether we're counting,
• 1:31
  measuring, or even when we say we have 0 homework.
• 1:35
  Can you imagine trying to do math without zero?
• 1:38
  It would be really confusing. Here's another fact that's sure
• 1:41
  to amaze you. Did you know that a circle has
• 1:44
  360°? And that's not just a random
• 1:47
  number? Long ago, the Babylonians
• 1:50
  divided the circle into 360°, possibly relating it to their
• 1:54
  approximation of 360 days in a year and their base 60 system O.
• 2:01
  When they were figuring out angles and circles, they decided
• 2:04
  to use that number O. The next time you see a pie cut
• 2:08
  into slices or you spin around in a circle, you're using a
• 2:11
  number that's been around for thousands of years.
• 2:14
  Now let's talk about something that sounds almost magical.
• 2:18
  Prime numbers. A prime number is a number that
• 2:21
  can only be divided evenly by itself and one.
• 2:25
  For example, 2357 and 11 are all prime numbers.
• 2:31
  But here's the crazy part. There are an infinite number of
• 2:35
  prime numbers. That means you could keep
• 2:37
  counting forever, and you'd keep finding new prime numbers along
• 2:41
  the way. Even computers are still
• 2:43
  searching for bigger and bigger prime numbers.
• 2:46
  Let's check in with our first trivia question.
• 2:49
  Are you ready? Here it goes.
• 2:51
  What is the smallest prime number that is greater than 10?
• 2:58
  The answer is 1111 is the first prime number you'll find after
• 3:02
  10. Here's another wild math fact.
• 3:06
  Did you know there's a special number called pie?
• 3:08
  It's not the kind of pie you eat, but it's just as cool.
• 3:12
  Pie is the number you get when you divide the distance around a
• 3:15
  circle by the distance across it.
• 3:17
  No matter how big or small the circle is, this number is always
• 3:21
  about 3.14. But here's the fun part π is an
• 3:26
  endless number. The numbers after the decimal
• 3:29
  point go on forever and ever without repeating.
• 3:33
  People around the world have memorized thousands of digits of
• 3:37
  π just for fun. Now let's get into something you
• 3:40
  use everyday your fingers. Did you know you can count to
• 3:44
  over 1000 just by using your fingers if you use binary
• 3:48
  numbers? Binary is a way of counting
• 3:50
  using only zeros and ones, and computers use it to do almost
• 3:55
  everything. If you use each finger to show
• 3:57
  A1 or a zero, you can actually count all the way up to 1023.
• 4:03
  That's a lot more than just counting to 10 on your fingers.
• 4:06
  Here's a quick yes or no question for you.
• 4:08
  Do you think there is a number that is both even and odd at the
• 4:12
  same time? The answer is no.
• 4:17
  A number can only be even or odd, never both at once.
• 4:22
  Let's talk about another incredible math fact.
• 4:25
  Did you know that if you shuffle a deck of cards, it's almost
• 4:28
  guaranteed that no one in history has ever shuffled them
• 4:31
  into the exact same order? There are more ways to arrange a
• 4:35
  deck of 52 cards than there are atoms in the observable
• 4:38
  universe. That's because 52 factorial is a
• 4:42
  gigantic number made by multiplying all the numbers from
• 4:45
  52 down to one. It's so big that if you tried to
• 4:49
  write it out, it would take up pages and pages.
• 4:52
  Here's a Did you know moment. Did you know that if you add up
• 4:55
  all the numbers from one to 100, the answer is 5050?
• 5:00
  There's a story about a young mathematician named Carl Gauss
• 5:03
  who figured this out when he was just a kid.
• 5:06
  He realized that if you pair up the numbers from the ends, like
• 5:09
  1 and 102 and 99, each pair makes 101.
• 5:15
  There are 50 pairs, so 50 * 101 is 5050.
• 5:21
  Pretty clever. Now for our next trivia
• 5:23
  question. What is the only number that is
• 5:26
  spelled with the same number of letters as its value?
• 5:32
  The answer is 4. FOUR has four letters.
• 5:36
  Let's move on to something called palindromic numbers.
• 5:39
  A palindromic number is a number that reads the same forwards and
• 5:43
  backwards. For example, 121, thirteen, 31,
• 5:49
  and 12,321 are all palindromic numbers.
• 5:54
  You can find palindromes and dates too, like February 2nd
• 5:57
  2020, which is the same forwards and backwards.
• 6:01
  Do you know what a perfect number is?
• 6:03
  It's a really rare kind of number.
• 6:06
  A perfect number is a number that is equal to the sum of all
• 6:09
  its proper divisors, excluding itself.
• 6:13
  The smallest perfect number is 6 because the numbers 1-2 and
• 6:17
  three all divide into 6, and if you add them up 1 + 2 + 3, you
• 6:22
  get 6. The next perfect number is 28.
• 6:26
  See if you can figure out why. Now let's talk about the magic
• 6:30
  of the number 9. Did you know that if you
• 6:32
  multiply any multiple of 9 by 9 and then add the digits of the
• 6:37
  answer together, you'll always get 9?
• 6:39
  For example, 9 * 3 is 20 seven 2 + 7 is 9.
• 6:45
  Try it with other multiples of nine and see for yourself.
• 6:50
  Did you know that the number 12 is called a dozen?
• 6:52
  And it's used in many ways In the real world, eggs, doughnuts,
• 6:56
  and even pencils are often sold by the dozen.
• 6:59
  That's because 12 can be divided evenly by two, 3-4, and six,
• 7:05
  making it a super useful number for sharing things.
• 7:08
  Here's our last trivia question for today.
• 7:11
  What is the only number that, when spelled out, has its
• 7:14
  letters in alphabetical order? The answer is 40.
• 7:21
  A four Y is the only number with its letters in order from A-Z.
• 7:26
  Let's finish up with one more wild fact.
• 7:29
  Did you know that the largest number with a name is called a
• 7:32
  Google? A Google has one, followed by
• 7:36
  100 zeros. That's way bigger than the
• 7:38
  number of grains of sand on all the beaches in the world.
• 7:42
  But mathematicians have even bigger names, like a googolplex,
• 7:46
  which is A1 followed by a Google of zeros that's so big you
• 7:51
  couldn't even write it out if you used every particle in the
• 7:53
  universe as a digit. To wrap up, let's review all the
• 7:57
  amazing things we learned today. We discovered that zero was a
• 8:01
  new invention in math history, and that circles have 360°
• 8:06
  because of ancient ideas about the year.
• 8:08
  We learned about prime numbers, the mystery of π and and how
• 8:12
  binary lets you count super high on your fingers.
• 8:15
  We found out about gigantic numbers like 52 factorial, the
• 8:20
  trick for adding numbers from one to 100, and the fun of
• 8:23
  palindromic and perfect numbers. We also learned some cool tricks
• 8:27
  with nines, the usefulness of a dozen, and the wild world of
• 8:31
  Googles. Thanks for joining us today on
