What is 7 x 22?
It's 154. The easiest way to multiply a number is to get it as close to a multiple of 10 as possible. In our case it's 20 x 7, which is 140. Then we have 2 x 7 which 14. 140 + 14 is 154.As an example: If we do 24 x 90, we essentially have 20 x 90 which is 1800 and 4 x 90 which is 360. Therefore we have 2160.
