AT THE OFFICE

Show your colleagues in the office this beautiful 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.
