Square numbers

Square numbers are formed by multiplying a number by itself.

The first four square numbers are:

1 \times 1 = 1

2 \times 2 = 4

3 \times 3 = 9

4 \times 4 = 16

A shorthand way of writing a square number is to use the power {2}. For example, {3}\times{3} can be written as {3}^{2}.

Each square number can be represented as a square of dots:
