External Math Resources? Anyone?
I got everything correct as far as setting up the class, subclass, and even the instance of Square...however, I did not set up the equation of calculating area correctly (embarrassing btw). Are there any external resources that would be recommended by Team Treehouse, or anyone, to refresh us on our math skills according to what is actually used in programming, especially the equations or functions that are used most frequently in Swift? Thanks and blessings!
