AT THE POST OFFICE

Multiply any 2-figure numbers together by mere mental arithmetic!

If you want 21 stamps at 26 cents each you can

easily find the total price in your head.

There were no carries in the method given before.

However, this only involves one small extra step.

- 2
**1 x 26 = 546**

The method is the same as before

except that we get a 2-figure number, 14, in the

middle step, so the 1 is carried over to the left

(4 becomes 5).

So 21 stamps cost $5.46.

**33 x 44 = 1452**

There may be more than one carry:

Vertically on the left we get 12.

Crosswise gives us 24, so we carry 2 to the left

and mentally get 144.

Then vertically on the right we get 12 and the 1

here is carried over to the 144 to make 1452.

Any two numbers, no matter how big, can be

multiplied in one line by this method.
