Someone told me that yesterday. Is it true or just a myth?

Roulette wheels have numbers from 1 to 36. The sum of these is ...















666 indeed - a peculiar co-incidence

According to the wiki:
"A legend tells François Blanc supposedly bargained with the devil to obtain the secrets of roulette. The legend is based on the fact that the sum of all the numbers on the roulette wheel (from 1 to 36) is 666"

Incidentally, there's a formula for calculating the sum of all the integers from 1 up to any given value.

0.5n * (n+1)

For n = 36, this evaluates to 18 * 37 which does indeed work out as 666.

Actually roulette wheels have numbers from zero to 36 (and double zero in the USA) ... but still add up to 666  ;)

Agreed - I didn't mention them as they don't contribute to the sum, I should have been clearer in my answer :(

The next question surely has to be...just what sort of anorak decides to add up
all the numbers on a roulette wheel in the first place?

Strange thing to think of doing. Very strange.

Proof that the Devil really does make work for idle hands?

Oi oi - some folks make a living from being mathematicians!

Plus, I was lazy and got a spreadsheet to do it for me :P

Well here's another one for all you career mathematician IA-ers out there to play with...

Apparently if you multiply 111,111,111 by itself, it produces this rather elegant answer...

12345678987654321.

Spooky or what?

So, get your spreadsheets out and answer this...

Is it true that 111,111,111 x 111,111,111 really = 12,345,678,987,654,321 ?

My mind tells me it should be right, Excel tells me that the answer is:12345678987654300 - which I know cannot be right, as when you multiply the 11 by 111111111, the last two digits are 21.

Excel has lots of bugs in it when it comes to large number manipulations. Its handling of the tail ends of statistical distributions is similarly "challenged"

And in answer to your question, look at doing it with long multiplication:

 11
 11x
---
110
 11

121
