Indivisible By for Dummies

Indivisible By is a phrase that we use when talking about numbers and how they relate to each other. It means that when we divide one number by another number, there is no remainder left. Basically, it means that the number you are dividing does not go evenly or completely into the other number.

For example, let's imagine we have the number 10. If we divide 10 by 3, we will get a remainder of 1. So we can say that 10 is not divisible by 3 because it doesn't go evenly into it. On the other hand, if we take the number 12 and divide it by 3, we will get a nice, even result of 4 with no remainder. Therefore, we can say that 12 is divisible by 3.

Now, let me explain it using a simple story. Imagine you have a bunch of toys that you want to share equally among your friends. If you have 9 toys and 3 friends, you can give each friend 3 toys, and there will be no leftover toys. In this case, we say that 9 is divisible by 3 because it can be divided into equal groups with no remainder. However, if you have 10 toys and 3 friends, you can give each friend 3 toys, but you will have 1 toy left over. So in this case, we say that 10 is not divisible by 3 because it leaves a remainder.

In summary, "Indivisible By" means that when you divide one number by another, there is a remainder left. It means that the number you are dividing does not go evenly or completely into the other number. So if someone tells you that a number is indivisible by another number, it's like saying the pieces don't fit together perfectly, and there's always something left over.
