Math Problems
This will probably get deleted But I am making this as a Math Problem thread. Here, you can post your math problems if you need help, or just stump other people with your hardest brain teasers! I will start off. Find the LARGEST 3-DIGIT NUMBER. You may use exponents, etc. Good luck!

I don't know.
How about.... -a(x - 3)-4 if a= -6 and x= 8. This is pretty easy. It's from Algebra I.

well... if a= -6 and it was -a, would that mean 6 (double negative)? or was that a typo or something?
if double negative, 26, right? What's 1+2+3+4+5+........... all the way to +100?

The largest 3-digit number? Isn't that just 999?
Or am I completely missing the point here? // is very tempted to put up his university-level calculus problems

lol yeah really, right?
We could get my dad on here... he is owns some electrical engineer consulatant company... sometimes he sits there in church and works out all these complicated math and diagram stuff... geezus. I, on the other hand, can't multiply (you'd think by 8th garde one would know how to multiply? I think im retarded)

That's nothing. I can't add.
On the other hand, the answer to your problem is 1+2+3+4+5+...+100 = 5050. And yes, I did that without a calculator.

Hehe... how'd you do it? did you actually do 1+2+3... or did you do 1+100 = 101 2+99=101 3+98=101 x 50?

The summation formula for 1+2+3+...+n actually reduces to (n+1)n/2
In this case, 100*101/2 = 50*101 = 5050

Hey, now here's a thread where I might actually know some answers! I love calculus (I know that is scary). It's funny how people think your smart when you study maths. I am doing third year maths at uni and I really don't feel smart. And I probably *should* be doing my structures assignment that's due on Monday instead of hanging out at the 'moot.
Hey, IP, you can put up your problems, see if I've actually aborbed anything over the last few years. All right, here's a sample from my assignment (I've think I've gotten the right answer): Evaluate the following limit: The limit as n tends to infinity of (n-sqrt(n+a)*sqrt(n+b)) Go on, I dare you to try it!

Oh, I wish I could. Unfortunately:
a) I can't tackle uni maths, as I am still tackling Maths Methods 1 & 2 (Logarithms- not too bad) b) I've had enough of maths for today. Tomorrow I have tuition- even more! Yay! BTW: I don't think 999 is the biggest 3 digit she may have been referring to. She said you could use exponentials, etc... (do they count as digits?) |

Well, 999 is the largest 3 digit number. Maybe she meant find the largest number using three digits and exponents.
