Well, it's the beginning of the year and I'm already stumped :-X.

The problem tells me to add, subtract, multiply and divide two given functions, but I am not sure how to continue since they are square roots.

Here are the functions:

f(x) = sq.root(1+x) and g(x) = sq.root(1-x)

Find: f+g, f-g, fg, and f/g

Any help is much appreciated.
