Does anyone know the answer to this?

1,2,3,4......48,49,50,51,52,53......97,98,99,100

Answer=5050

To get this answer you must add 1+2,3+4,5+6......and so on.This would take forever.There is a short way to do this by useing the numbers above.Does anyone know how?

Damn. I knew sixth grade math would come back and bite me in the ass.

100x50=5000
5000+49=5049
5049+1=5050

And they said being a smartass won't do me any good.

Do your own fucking homework Darren, or ask your mom.

100+1 = 101, 99+2 = 101 also, 98+3 = 101, etc. Obviously you can work this equation out 50 times, each time equaling 101. 101 x 50 = 5050. This is incredibly easy.

Yeah, atoga, you should be doing mushrooms instead of being so smart.

yeah, wtf?

Atoga is on the right track. Simply average the lowest number in the range and the highest, then multiply by the number of numbers in the range.

So we have (((1 + 100) /2) x 100)

1 + 100 = 101

101 / 2 = 50.5

50.5 x 100 = 5050

It's useful for doing things like figuring out how many items are stacked in a pyramid where each tier is one less than the next lower level.

And before anyone goes on about how smart anyone is, just remember that Gauss figured this out when he was 6.

That's cause he has two s's in his name. Shiz.

Wouldn't it be quicker just to add them up :DDDD

OTB - same thing. None of your complex formulae K THX

Mushrooms are a drug for idiots? The proof of that is iohkus.

Hey, if you want to sit down and add 50 pairs of numbers together because you haven't figured out that multiplication is a rapid way of doing repetitive addition, you go right ahead.

If you consider that forumula to be "complex" I suggest your dabblings w/mathematics be restricted to criticisms of the paint-by-numbers daubs of school children.

BTW, you're making Robert Hughes cry.

I remember a teacher giving us this shit in 5th grade... It's very simple, what the big deal?

And, Gauss is gay. He keeps haunting me in all of my "scientific" classes.

atoga · Post by **atoga** » Sun Sep 21, 2003 3:26 pm

OTB - I'm just saying using a formula is illogical for such a simple problem. There's no repetetive addition here. If I was doing something a lot harder, then I would, but otherwise, it's stupid.

Megatron · Post by **Megatron** » Sun Sep 21, 2003 4:53 pm

not really? adding every number up might take a bit longer than to write a short formulae that you're basically doing anyway or something.

that thing is called tha dope arithmetic sum

Yeah, you're doing the same thing but using an easy formula instead... That's not very "illogical" or "complex" if you ask me. ATOGA = LOSE

I was with Atoga on this one, itÃƒâ€šÃ‚Â´s the way we inteligent but not math savvy people do IT. OTB is using the matemathically correct formula, so heÃƒâ€šÃ‚Â´s just a nerd. :roll:
