What is a remainder?

Sometimes, it is not possible to divide one number by another exactly.
Anything left over that cannot be divided exactly is called a remainder.
When you are solving problems and there is a remainder, you need to know what to do with it.

Division with remainders
When you divide, the numbers don't always divide exactly. Anything left over after dividing is called the remainder.
For example, look at this division calculation:
7 ÷ 2
If you divide 7 by 2, you can make 3 groups of 2, which equals 6. However, there is 1 left over.

You would write it like this:
7 ÷ 2 = 3 r1
The 'r1' shows there is one left over.
When solving problems with division, you have to decide what to do with the remainder.
Sometimes you have to round the answer up to the next number. Sometimes you round down.
Which action you take depends on the problem that you've been given.
