What is the Square of a Number?

The square of any number is the product of the number and itself.

e.g. The square of 4 is the product of 4 and 4

i.e. 4 × 4 = 16.

Therefore the square of 4 is 16.

The squares of numbers are given below:

Number:	Square:
1	1² = 1 × 1 = 1
2	2² = 2 × 2 = 4
3	3² = 3 × 3 = 9
4	4² = 4 × 4 = 16
5	5² = 5 × 5 = 25
6	6² = 6 × 6 = 36
7	7² = 7 × 7 = 49
8	8² = 8 × 8 = 64
9	9² = 9 × 9 = 81
10	10² = 10 × 10 = 100

Perfect squares are gotten by multiplying a whole number by itself. e.g. 1, 4, 9, 16, 25, 36, 49, 64, 81 and 100 are perfect squares.
