Man Says He's Cracked Code to Multiply Any 2 Numbers in Your Head-He'll share it for a Price
FoxNews.com ^ | 08-11-09

Posted on 08/11/2009 7:48:27 AM PDT by rawhide

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."

True to his word, Clay multiplied a pair of five-digit numbers in just seconds and wrote the answer on a single line of his yellow scratch pad, News & Observer reported. No calculator. No zig-zagging numbers cluttering the page

My father, born in 1896, with only an 8th grade education could do that. He never told me how he did it but, at the time, I wasn’t interested.

I believe I read how it is done in a book called Math Tricks.

Easy.

Develop a matrix.
Cross Multiply.
Add.

It’s easy.

It’s easier to buy a calculator.

It’s easiest to estimate.

Ok, I just multiplied 3456 x 9845. My mind just came up with this number: 329758670, am I right or just loony? (no calculator)

Right or Loony? I don’t know (it’s a false dicotomy), but I know you’re incorrect by 295,734,350 (as determined by my Monroe 8125 calculator!).

did you know that any number multiplied by 999 is 999 by adding up the separate digits?

Example: 999 * 2009 = 2,006,991.00

2+6+991 = 999!

the retired pharmacist has copyrighted the formula, "How to Multiply Any Number by Any Number in Your Head,"

Much to his dismay, he's about to discover that copyright protects the expression but not the idea...

Well, 4000 x 10000 = 40,000,000. Your answer is 329,000,000+, so I’d say you’re off by an order of magnitude.

999 x 777= 776223
776+223=999

You’re right. Neat.

999 x 458956= 458497044
458+497+044=999

My 4th grade math teacher taught us the "code" using numbers ending in 5 as a starting point.

15 X 15 = 1 X 2, (first digits) and 5 X 5 = 25. therefore 15 X 15 = 225.

45 X 45 = (4X5=20) and (5X5=25) so 45X45=2025.

Other numbers work as well. For example 33 X 33= (33+3=36X3=108) and (3X3=9)so 33X33=1089! TA DAH

Today I use Excel, Cell Phone and other electronic devices which are as accurate and cost less than $33 for the "copyrighted formula"!

From the Raleigh News-Observer story Fox News is citing in the OP:

Clay's method is best explained on paper. Suffice it to say you multiply the digits on the right, cross-multiply and add the digits in the center, then multiply the digits on the left.

Not a particularly novel concept to me. You will still need a highly nimble [read: regularly exercised] memory to accomplish the calculation in your head, and alas, there's no silver bullet magic trick in that, just regular practice.

Darnit! I would have been willing to pay the $33 just to be able to show off, too, but I'm not parting with the cash if his 'trick' means I also have to give up my well-earned trademarked mental laziness.

AD! Pick up the White Courtesy phone, please.

Interesting. Does this work only with numbers ending in 5?
How about 95x95?

I also multiplied 87x36 using your formula, and I cannot get it to come out to the correct number?

"There may not be anybody else in the world who knows how to do this but me," Clay

And the two guys who paid you 33 bucks.

“Much to his dismay, he’s about to discover that copyright protects the expression but not the idea...”

Except in software patents, which do protect the idea, which is why they are such a disgrace.

It’s like copyrighting the idea of boy meets girl, boy loses girl, boy gets girl, and then charging a license fee to every fiction writer who uses that plot line. DISGRACEFUL.

I couldn’t tell from your example how you picked the multiplier for the first digits.

1x2, 4x5... How do you know the multiplier for the first digits?

Also didn’t follow the example for using it for other numbers.

Or (1000*2009) - 2009 = 2006991

example 65X65=4225.

1st digit is 6. Add 1 to one of the digits. 1+6=7. Then multiply that times the second first digit so you get 6X7=42. 5X5=25.

Answer to 65X65=4225.

905X905=819025! 90X90=8100. Add 90 to sum and get 8190. Add 25, (5X5) and you get the answer 819025! excel or cell phone is easier!

I am no good at multiplication. But I can add four 4 digit numbers in the neighborhood of 1 second.

I don’t know. You can probably describe it algebraically. The key to schemes like this is more about utilizing the capacity of human memory than any particular trick.

It’s kind of sad because it isn’t worth $33 these days. I bought a free iPhone app that’s even faster.
