Really!Â Tomorrow is 11-11-11.Â Happens once a century.Â And of course, this 11-11-11 will be the best ever, because we have the best way to commemorate it:

For those of you with younger children, you can celebrate this way:

Everyone is entitled to his own opinion, but not his own facts.

Richard W. Crews says

That song was … terrible in compared to what it could/should have said. up ’til 9 is pretty basic, but they blew that. can I say this without a movie? ” what is 11 times your number (single digit)? Well, with 11 you get two numbers! 7 gets 77! 3 gets 33! see?”

But here is where they really blew it – on the next 90 numbers (10 – 99_ :

“so some bigger numbers, let’s take 11 times 17, OK? First, take the 17 and split it, put the 7 over to the right, and push the 1 over to the left. we’re gonna’ put a nother number in the middle, between that 1 & 7. Go back to the 17, which is a 1 & a 7, add them together, 1 + 7 = 8. Put that 8 in the middle so you have 187. That’s the number; 11 x 17 = 187. 11 x 26 = 268. 11 x 67 = 737. Wait!wait!wait? Splitting the 67 should have a 6 over on the left. What’s that 7 ? Well, when you added the 6 & the 7, which is 13, you have to carry the one. It is still multiplication, this is just a way to see it easier, but it’s still “carry the number stuff’. So try 11 x 74 = 814, right? ”

You could keep going :

” But maybe think about it this way, which is a real way and not a Parlour Trick Way, a way that serves one well with other numbers besides 11, someday :

” That’s a fun trick, and impressive when it’s used, but here’s the real way to think of it : What is 11 times any number? It’s 10 and another. So 11 times 17 is ten 17s, which is 170, then another 17 so it’s 187″

On an even nerdier note: you can easily tell if a number is divisible by 11 by adding up alternating digits into two totals. If the totals are equal of differ by a multiple of 11, the number itself is divisible by eleven. So 4,785 is divisible by eleven, since 4 + 8 = 7 + 5. Or 726; 7 + 6 is eleven greater than 2.

This could be the single nerdiest thing ever written on a very nerdy website. Congratulations! I’m tempted to say that your prize is — a toaster.

Jonathan: The music would have sounded a lot better if it had been recorded in Doubly.

Congratulations: You’ve opened Samefacts to the wonders of number theory.
