31 people are in a room. they each shake hands with one another
How many handshakes are given?

I think that the 'trick/twist' to the question is if YOU'RE one of the 31 people and everyone shakes hands with each other than you dont shake hands
with your self.
So technically its 31 people and each one shakes hands with 30 people.
But I could be totally wrong!

hmmm... remember not to count the same handshake twice- I'm too tired to add it up right now but I'm pretty sure the algorithim would be
30+29+28+27...etc.
The first guy would shake hands with 30 guys, but then you wouldn't count the second guys handshake with the first again so he only gets 29, and so on
down the line.

Yep. GREAT JOB!
There is a algebra formula too. I think its n(n-1)/2. RANDOM would know that one.

Lionel said "algorithim."
Well, its this place where nobody works, and the pigs don\'t give you any shit. Everyone smokes weed and gets drunk all day. Its a place where
cunts like me and you can truly take it easy and relax. Know what I mean?

I didn't remember the formula, but the addition gets pretty easy with 30 + 29 + 28 + ... + 1 (and I suck at arithmetic). You can pair up the first
and last numbers, and you can combine them.
30 + 1 = 31
29 + 2 = 31
28 + 3 = 31
. .
. .
. .
16 + 15 = 31
So you just get 15 pairs that add up to 31, and 31*15=465.

n(n-1)/2 I believe is the equation. Random that example is awesome though. Crazy how those numbers come out like that every time. Pairing them up and
shit.

clevo,
not as amazing as it seems... all you're doing is subtracting 1 from the first number and adding 1 to the second number.
i think you're right about the equation though. the formula should work with an odd number or terms, too, but my way means you have to be careful..
like if there were 32 people, you'd do 31+1 and so on, but then you'd get stuck with 15 by itself.
holy fuck, i'm a nerd.

oh, and clevo, there's a similar formula for quadratic equations that's much cooler... you hate FOIL? the equation takes care of it for you. it's a
neat thing where you create this "tree" and just combine collected "branches". if you're interested, i'll find you a link... it really is one of
those things that fascinating in a nerdy way.

My final math class is going on right now. It's all about things like this. Its a education math clas and its how to do things as a young child or how
to figure problems out a different way than normal It's hard as nails for me of course, but you'd have a blast in it I'm sure. Deals with a lot of
methods and stuff.

okay lets get nerdy
what is formual for figuring out how many possible 3 number combos on a standard combination lock,
let's say from 0 to 31
and we can do it both ways with numbers being able to repeat and without
repeating
000
001
to 31 31 31
not repeating
and 012
013
014
how many combintaions are possible for both
I did this one saturday morning when I was 12 for the hell of it...
damn if I remember how or remember the answers.

Oh, and the thing I was talking about before is Pascal's Triangle. http://en.wikipedia.org/wiki/Pascal's_triangle
To the right of the "Contents", wikipedia has a neat little illustration of how it's constructed, so you never have to remember the terms. But it's a
quick and easy way to write out the expansion of anything of the form (x+y)^n. The triangle gives the coefficients on each term.
(x+y)^0 = 1
(x+y)^1 = x + y
(x+y)^2 = x^2 + 2xy + y^2
(x+y)^3 = x^3 + 3(x^2)y + 3x(y^2) + y^3
Compare that with the first four lines of Pascal's triangle...
1
/ \
1 1
/\ / \
1 2 1
/ \ /\ / \
1 3 3 1
To get any number, just add up the numbers that have lines going down to it... so the next line would be...
1 4 6 4 1
