Title: A little trick.
Post by: Bossieman on April 30, 2001, 09:33:04 AM

You want to lear  to do multiplication of number with a 5 in the end?
e.g 35x35=?
easy: 1225

here is the trick:
 take the first number (3) and multiplicate it with itself plus one (4), that gives 12, then ad 25 to the end. and you got 1225

another one:

65x65

take the first number (6) and multiplicate it with itself plus one (7), that gives 42, then ad 25 to the end. and you got 4225

answer:4225

easy, isnt it?

yea but does the number you are multiplying have to be itself

like 65 x 65 is one example you used but does it work with like say 35 x 65

i am guessing not seeing how i have no time to try it out

Quick English lesson, my Swedish compadre...

It\'s MULTIPLY, not MULTIPLICATE.

Perhaps you got confused with DUPLICATE?

This is my good deed for the day. :D
