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)

Khan Academy is nicely structured and has lots of free videos and exercises. For what it's worth, I usually like Sal Kahn's take on things. He's often mindful to take a step back and think about motivation and intuition before diving into the computation. This is a good habit to have when you're learning mathematics.
