3.1 Writing Formulae Using Numbers

Multiplication and division are inverse operations. This means that each one is the opposite of the other. Whatever one does, the other undoes.

This means that any multiplication can be rewritten as a division and vice versa.


If we start off with a division, we can rearrange it to form a multiplication.

Thus 8 =	48	can be rewritten as the product (multiplication) 6 x 8 = 48.
	6

We don’t bother offering an alternative 8 x 6 = 48 because everyone knows that it doesn’t matter which number goes first with multiplication , the answers will be the same.
