00:00Today we are going to learn about division. Division is such an awesome thing to be able
00:05to do. And you're going to have it all figured out. You're going to learn how to divide in
00:09this video. And we're going to start off with a story. There's this kid named Ethan and
00:16Ethan loves carrots. He loves carrots so much. He loves to snack on them. He loves when he
00:23gets to eat them. They're crunchy. They're tasty. Yeah, carrots are awesome. In fact,
00:30I'm literally eating a carrot right now as I'm speaking. Carrots are great for your skin.
00:36Carrots are great for your eyes. They're amazing. They're a great snack. And Ethan loves them.
00:42Well, Ethan has two friends over, Kevin and Chloe, and they start to get hungry. Of course,
00:52they all love carrots because carrots are like the perfect snack. Now in Ethan's house,
00:58there are only three carrots. They're just three carrots. We are going to have to divide
01:06the three carrots amongst the three kids. So let's figure this out. How many carrots
01:12does each kid get? Do you know? Uh-huh. Each kid gets one carrot. Pretty simple, right?
01:24Three carrots, three kids. Each kid gets one carrot. Hey, did you know we just did division?
01:32Uh-huh. We just did division. Division is pretty simple. You see, division is splitting
01:40a number up by any given number. That's it, just splitting a number up. Let's look at
01:48our story again. There were three carrots, and we divided those three carrots by three
01:55because there are three people, right? The three kids that love carrots. And the answer
02:01of how many carrots each kid gets is one. Three divided by three equals one. Notice
02:12right here is the division sign. This is what it looks like. When you see that sign, you
02:18can just say divided by. So this reads three divided by three equals one. Let's try another
02:28example of division. Let's say there are eight presents. Eight presents, and there
02:33are four women, and we want each of the women to get the same amount of presents as the
02:39other women because we want it to be fair. Notice the division sign. We are going to
02:47divide or split up eight by four. Remember, to divide is to split up. Let's split these
02:57presents up into four equal groups. One, two, three, four. Alright, how many presents does
03:06each woman get? Uh-huh, two. Each woman gets two presents. Isn't that cool? Division is
03:17so much fun, and it's so easy. Remember, division is splitting a number up by any given
03:25number. That's it. Alright, now it's time for division facts. We're going to learn some
03:36pretty interesting facts about division, and you're going to be like, what? Oh my goodness!
03:43Like secrets. This is super cool, okay? So just look around, alright? Make sure it's
03:49all clear. Alright, it's time for division facts. The first fact is this. You can never
04:01divide by zero. It's true. You can never divide by zero, even if you're a rule breaker and
04:07you're like, I'm going to do whatever I want. You still can never divide by zero. In fact,
04:14if a teacher ever gives you a test and you see a problem where you have to divide a number
04:19by zero just right on the test, undefined. Because that's exactly what that answer would
04:26be. Undefined. It's impossible. Kind of like Mr. Whiskers' math skills. Does Mr. Whiskers
04:34do math in his head all day long? Who knows? His math skills are undefined. We just don't
04:40know. It's impossible to know. You know, Mr. Whiskers might know how to do division. Who
04:46knows? Undefined. You can't divide by zero. You can never divide by zero. If you ever
04:57see any division problem dividing by zero, just write undefined. It's impossible. It's
05:04impossible. So just write undefined. The second fact is this. You can write the division sign
05:15three ways. Uh-huh. Not just with that traditional division sign. You can write it like the division
05:21sign or you can write a division problem with the slash or with a horizontal line. For example,
05:32look at this. Twelve divided by three equals four. That's the original division sign, the
05:39one that you might see more regularly. But here is the same equation written in a different way.
05:48Twelve divided by three equals four. It's still a division sign, but it's a slash. It means the
05:55same thing as the original division sign. Remember, the division sign can also be a
06:02horizontal line. Twelve divided by three equals four. That looks like a fraction, doesn't it?
06:09The line in a fraction means divided by. These are the three ways that you can write the division
06:20sign. Pretty interesting. All right, the final fact is this. Okay, this is so awesome. You can
06:33flip the number of groups and the number in each group and the division problem stays true. For
06:41example, ten divided by two equals five and you can flip the two and the five and it stays true.
06:48That means ten divided by five equals two. Isn't that interesting? Ten divided by two equals five
06:59and ten divided by five equals two. You can flip the number of groups and the number in each group
07:06and it still stays true. Or look at this. Eighteen divided by six equals three. Remember, we can flip
07:15the number of groups and the number in each group and it still stays true. So we could switch the six
07:22and the three and it stays true. So eighteen divided by three equals six. The six and the three can be
07:31flipped. So eighteen divided by six equals three and eighteen divided by three equals six. Pretty
07:39nifty. Those were some cool facts. You know, division is a great time. Division is splitting
07:45a number up by any given number. It's a lot of fun and we hope you learned a whole lot in this video.
