Visit Khan Academy, they cover every topic from basic arithmetic to algebra, calculus and a bit more advanced algebra.

If you ever plan on studying anything science related in college, your algebra will have to be very solid. Calculus for example, is relatively easy (the calculus concepts), it is the algebra aspect that can prove to be the toughest if you don't have a firm grasp of it.

Also know your trig.

fvck optimization

[DCL]

(40 + x)(50 + x) = 3000
2000 + 90x + x^2 = 3000
x^2 +90x = 1000
x=10

half of x = 5 for each side

The only problem I didn't finish on my calculus finals was the optimization problem. It was the section we covered and I didn't get around to doing the homework. I already dislike word problems enough.

First part: f(-x)=-2x+8
