Hey Freak!

So, right now, I'm working on putting up my Expo pictures, and I needed a break (there's quite a few up right now, if you care to look). And then, for some reason, I remembered these little tidbits about numbers with 1 as the only digit.

I'm sure a lot of us have seen trivia/odd facts/general bullshit email, where it shows the equation:

111,111,111 x 111,111,111 = 12,345,678,987,654,321

Well yeah, I coulda told you that. 111,111,111 is made up of 9 ones. Now, let's take one we all know for sure:

11 x 11 = 121

11 is made up of 2 ones. See the pattern? 2 ones, and the answer is, you count up to two, then back down. 9 ones, and you count up to 9 and back down, and that's the answer. So:

11,111,111 x 11,111,111 = ?

Easy. 8 ones; the answer is 123,456,787,654,321. This works for squaring all numbers less than 9 digits, whose only digit is 1.

OK, *I* think it's neat. Wha, you want something more practical? This one's easy. The quickest way to figure out any whole number multiplied by 11.

So, what's 4,152 x 11? I can do that in my head. The answer is 45,672.

How is that easy? Well, for anything multiplied by 11...

The last digit is the first last of the multiplier, in this case, 4. The next digits are the first two digits of the multiplier, added together (here, 5 + 2, then 1 + 5, then 4 + 1), and the first digit of the answer is the first digit of the multiplier. So the answer is 45,672. If the sum of two of the digits is more than 10, then you'll have to do some carrying, but still, this is pretty easy.

So, 7,386 x 11 = ?

6 is the last number
8 + 6 = 14, so 4 is the next number (carry the ten)
3 + 8 = 11, plus one (carried from the previous number) equals 12, so 2 is the next number (carrying the ten again)
7 + 3 = 10, plus one equals 11, so 1 is the next number (carry the ten again)
7, plus one (carried from the previous number) equals 8, so 8 is the first digit.

So the answer is 81,246.

Are we having fun yet?

So there. You can't say that I never taught you anything.

Nah, you're not the only geek around. I heart number games. My mom used to get those Childcraft Annual things and they always came out with some special book per year and one year (personal fave) was Mathematics and Logic games. That was the great thing about not having cable as a kid. I actually learned shit.

:boggle:
I'm math is hard barbie. But I'm sending it to my mom. She'll love this she's a retired math professor

Damn, this is really confusing me, so I'm off to look at porn

I've just gone retarded. Wow, numbers scare me.

hehe told you my mom would like that. Here's what she replied with:
Write :
0
1
2
3
4
5
6
7
8
9

Then one digit to the right write:

9
8
7
6
5
4
3
2
1
0

That gives you:

09
18
27
36
45
54
63
72
81
90

See any patterns here?

I am embarassed to say that I work in the Adult Industry!

The girls always used to look all so glamourous at these shows.

Now they are all either fat or skinny skanky tore up sluts with some kind of substance problem.

Lay off the double stuffs and cream pies (And I don't mean food) and pull your shit together.

Where some nice clothes.

Hire somebody other than your tweeker best friend to do your makeup.

Pick a hair color that suits you.

And for crying out loud, drop the fucking attitudes.

Remember, you suck cock for a living!

I HATE math and numbers, except money of course - so I will move on to something more fun; )

You can do Noelle's on your hands, but it's pretty hard to explain without a visual...

You have entirely too much time on your hands.

wow. that has got to be the nerdiest post ever. ever.

-blink blink-

What?

I absolutely love this shit. And I always will.

Mikey, you totally just made my day! I love goofy stuff like that. Even though math is hard to me, I love to stun and amaze my friends at all the nerd parties I go to!

Noelle's no. 9 trick has a practical application that works for figuring out a checkbook or accounting error. If you are off by a number divisible by 9, then you should know that you transposed a number somewhere.
