THE
SPEED MULTIPLY TRICK: Works best with two
digit numbers.
*The following text is taken as an example from the book .
We at themathlab.com highly
recommend this book if you really want to become a mental math
whiz.

"To
multiply two 2-digit numbers without showing work, first multiply
the ones digits together, then 'cross-multiply,'
and finally multiply
the tens digits together.

Make
sure to carry whenever a product exceeds 9. As you will
see in the examples below, you must work your way from right
to left to perform this trick.

EX
1:
12 x 23 = ?

Multiply
the ones digits: 2x3=6 (ones digit answer).

Cross-multiply
and add: (1x3)+(2x2)=7 (tens-digit answer).

Multiply
the tens digits: 1x2=2 (hundreds-digit answer).

Combine:
276 (the answer).

EX 2:
31 x 24 = ?

Multiply the ones
digits: 1x4=4 (ones digits answer).

Cross-multiply and
add: (3x4)+(1x2)=14 (use the 4 as the tens-digit answer, and
carry the 1).

Multiply the tens
digits, and add the 1: (3x2)+1=7 (hundreds-digit answer).

Combine: 744 (the
answer).

Note: This trick will also work on numbers with zeroes and
decimal points.

Also as you are cross-multiplying,
it is generally easier to begin with the larger product and
then add the smaller product."
