/sci/ - Science & Math

I have two sons. One is in second grade and the other is in fifth. I don't like the math programs at their school as it seems a tad...low. (The second grader is still adding single digits as homework!)

I ran across this: http://www.aleks.com/

However, it's a bit cost prohibitive. Does /sci have any alternatives?

If I have some C++ programming questions, would you guys be able to help me? I'm having a hard time wrapping my head around the math.

I'm supposed to create a simple program that takes a number from the user and prints out the Fibonacci sequence. I'll post the code I have so far if anyone responds, and your help would be greatly appreciated.

Btw, I now realize I screwed myself by taking a programming class, since I struggle intensely with math. Sorry...

The profit P, in dollars for a certain manufacturer selling x items is
P(x)=5x^2 e^(-x/500)
use calculus(small change formula) to estimate the change in P(∆P) as the number of items changes from x=100 to x=105, compare this with the exact value of ∆P
