N.C. Man Says He's Cracked Code to Multiply Any 2 Numbers in Your Head -- and He'll Share It ... for a Price

A North Carolina man who allegedly cracked the code to mentally calculate any multiplication problem is now offering to reveal his secret - for the bargain price of $33.

Albert Clay said he came up with his system as a high school junior, but never showed anyone aside from a high school math teacher who shrugged off the achievement, the News & Observer reported.

Now 75 years old, the retired pharmacist has copyrighted the formula, "How to Multiply Any Number by Any Number in Your Head," and hopes to demonstrate it in schools, books or even personal mailings to anyone who'll send him $33, including postage, the paper reported.

"There may not be anybody else in the world who knows how to do this but me," Clay, told the News & Observer. "Zip, zip, zap and add 'em together."

Very odd.   :-)

No, my friends, there’s only one really progressive idea. And that is the idea of legally limiting the power of the government. That one genuinely liberal, genuinely progressive idea — the Why in 1776, the How in 1787 — is what needs to be conserved. We need to conserve that fundamentally liberal idea. That is why we are conservatives. --Bill Whittle

There's a simple way to find the square of any number ending in 5 , between 0 and 100.

452 = 4X5 and put 25 on the end result. 2045

 :doh: It was a typo, but that works for any number like that.

852 =7225
8X9 =72(25)

I know that if I multiply 0x33 the result will be 0.

Guess how much money you will make off from me now.

152 = 225
15 is 1/2 way between 10 and 20
10X20=200 add the 25 = 225

252=625
25 is 1/2 way between 20 and 30
20X30 =600 add the 25 =625

See the pattern, now?  It's hard to explain this way. 90X100= 9000 ,  9000+25=952=9025
