Hi and welcome to Math Antics. In this article lesson, we’re gonna learn the basics of division. And if you really understand these basics,. then it’ll make it much easier learning how to do ‘long division’ which is the subject of our next article. Okay, so here’s how basic division works.
You get a problem like this one: 9 divided by 3,. which means you have a total of 9 and you want to divide it into 3 equal groups. And if you can remember that 9 is an answer to one of the multiplication facts,. or that it’s an answer on the multiplication table, then you can see that since 3 × 3 is 9, then 9 divided by 3 is 3. It’s that simple! Well… at least it WAS that simple when you learned about the fact families.
Now it’s gonna get a little bit tricky because most division problems aren’t quite this easy,. like this one: 9 divided by 4 The trouble here is that 9 and 4 aren’t part of a fact family,. so you can’t just find the answer on the multiplication table. That’s because 9 is not a multiple of 4. There’s no whole number that you can multiply 4 by and end up with 9.
That means that 9 can’t be divided equally into 4 groups without having something left over. Like if you had 9 cookies and 4 kids, each kid could have 2 cookies but there would be 1 left over. And in division, that left over amount is called a “remainder”. So the answer to 9 divided by 4 is 2 with a remainder of 1. Alright, so it’s not that hard to figure out a simple division problem when you have a picture like this,.
but what about when we just have numbers. To do that, we use a special division procedure. Up until now, you probably have used this division symbol the most. It works well for very simple division problems, like the ones in our fact families. But, now that we’re gonna be doing some harder problems, we need a new division symbol… this one….
