division

The meaning of division is the act of dividing, or the process of separating.

We can separate a set into subsets. Think of a ruler which usually shows a centimetre scale on the top. There are subsets within each centimetre, namely millimetres.

We can divide a number into different components. It’s possible to divide the number 38 several ways, for example 30 + 8 or 19 + 19.

Division is also a model of dividing. We can deal with 21 ÷ 7 as how many sevens are there in 21.
