i had a pretest today, and the bonus question involved subs..i dont know how to type them, but its the opposite of powers. the real test will probably have a similar bonus question, and i need to get all the points i can to make up for a test i bombed recently, so can someone please give me a quick lesson on sub qualities?
also, the question was something like this:
solve for b
A=y-(b sub1+ b sub2)
