Solve this, smart ones.

3x^2+4x+7=0

-4±√(-68)/6

I have no clue

I know factorials.
1! = 1.
2! = 2.
3! = 6.
4! = 24.
5! = 120.
6! = 720.
7! = 5040.

Anyone here do calc? If so, I have a joke:

∫1/cabin*dcabin

natural Log cabin + sea
heheheheheheh
Old joke
EDIT: I'm not to calculus yet, just Adv. Trig, but that's one away, so I knew this joke from my friend badger, who is a year older and ahead

Here's a word problem for ya (if you've seen it before don't give it away, por favor):

There are 1000 shut doors in a really long hall and 1000 kids in a line. The first kid goes by and opens every door. The 2nd kid closes every other door (door 2,4,6, etc.) The 3rd kid goes to every 3rd door (3, 6, 9...) and  closes the ones that are open and opens the ones that are closed.The 4th kid goes to every 4th door and does the same. You get the point.     This continues until every kid has gone. When it's all over, what doors are open?

Note: This is not one of the trick question word problems, so don't get too clever. (For instance the answer is not "None- the wind blew them shut.")

Note #2: The math here doesn't have to be too complex. I did it before I had any algebra. 

Note #3: If you Google (or Bing or Yahoo or whatever) this problem, don't say anything.

This is a hard one, whats 3+0?

If I say 3, you say it's 30. If I say it's 30, you say it's 3.

I got that the open doors were the squares of the numbers 1-31. (So 1, 4, 9, 16, and so on.)

No actually, I was not thinking of that and 3+0 does not equal thirty. Maybe on another planet like Derp but not on Earth.

Planet Derp?

WOW. How did you figure that out?

Just whipped up a little script in Scratch. This is a programming website, isn't it? 

5*4*3*2*1=120 
Used for determining stuff like how many ways people can finish in a race and stuff like that.
