# How can an array help me multiply?

## What is an array?

As array is a group of things arranged into rows and columns.

You can use arrays to help you multiply two numbers.

One number will be the number of rows.

The other number will be the number of columns.

So 2 x 3 would make 2 rows and 3 columns.

### Top tip

It doesn't matter which way round the array is. 2 rows of 3 is the same as 3 rows of 2.

Use whichever way works better for you.
