Multiplying by itself (squaring)
In mathematics, we call multiplying a number by itself squaring the number.
We call the result of squaring a whole number a square or a perfect square.
You should be able to fire out the answers to all squares up to `12times12`
It’s just got to be inbuilt.

To help you remember these squared numbers try these:
4 x 4 = 16

This 4x4 is a big machine I’m going to get one when I’m 16.
5 x 5 = 25

Multiply by 10 and half the result.
6 x 6 = 36

Chicks, chicks, dirty chicks, six times six is thirty six.
7 x 7 = 49

Seven times seven commit a crime when they rob the number forty nine.
8 x 8 = 64

I ate (8) and I ate (8) until I was sick (6) on the floor (4) equals sixty four.
9 x 9 = 81

He stood in line (`9xx9`) and ate one ton (81).
10 x 10 = 100

Just put a zero on the end.
11 x 11 = 121

The 11 players of the soccer team were told to mark the opposing 11 players one to one (121).
12 x 12 = 144

12 times 12 is 144,
There is no more!
