Easy way for MULTIPLYING

Method for multiplying numbers where the first
figures are the same and the last figures add up to 10.

32 x 38 = 1216

Both numbers here start with 3 and the last figures (2 and 8) add up to 10.

So we just multiply 3 by 4 (the next number up)
to get 12 for the first part of the answer.

And we multiply the last figures: 2 x 8 = 16 to
get the last part of the answer.

Diagrammatically:

And 81 x 89 = 7209

We put 09 since we need two figures as in all the other examples.

Try some by Urself:

1)  43 x 47 =

2)  24 x 26 =

3)  62 x 68 =

4)  17 x 13 =

5)  59 x 51 =

6)  77 x 73 =
