Looking for websites to brush up on algebra skills needed for calculus I've enrolled in an 8 week online Calculus 1 class, we're currently in week 2 and while I understand the calculus concepts (average rate of change, limits) I'm having a hard time on my homework due to not having a strong background in algebra. Are there any websites that I could go check out that would help me brush up on algebra, I'm mostly struggling on factoring, simplifying, square roots, Pi)

Paul's Online Math Notes may be a good place to check out. You can either look it up on google or go to it here http://tutorial.math.lamar.edu/
It can help out with algebra as well as calculus.
