Hi,

I would like to add one more shortcut to Maverick's quite old but very useful post.

Here it is:

Multiplication of just over and just under numbers

97*104

97 -3
104 4

101 -12
100 88 (subtract 1 from the result of cross addition. take the complement of the right

Ans: 10088

103 3
96 -4
99 -12
9888

cheers!:)
