That's basically how my brain feels right now. I spent most of this afternoon trying to figure out how to complete 1 physics problem. I finally figured out how to do it, but it wasn't my text book that helped. It was this Physics book a friend gave my family, after they found it in a dumpster.

For some reason, the authors of my text book decided to leave out the algebra for the one example problem that would have helped me so they could have a question for the end of the chapter.
