Hello Everyone,

To get the product of two the same number.

Example:

12 x 12 = 144

To get et easily,

Multiply the first number (1x1) = 1

And then the last digit (2x2) = 4

And then to get the mid number simply like this (1x2) + (1x2) = 4

you will get an answer of 144...

try this one 26x26 ? =

Hi Maria

Why not try this alternative way using easy square numbers....

26 x 26

This is 4 away from 30 so...... add and subtract 4 to 26 to get 22 x 30 = 660

Then add on your 4 squared = 660 + 16 = 676

eg 13 x 13 = (10 x 16) + (3 x 3) = 169

Neat eh? - hope this of use.

I think, therefore I am.
