I need help with math, specifically how to do a problem using formulas.
You don't what type of math you are doing. Is it trig,algebra, calculus or something else. However, just go to google and type in solving the type of math you are looking for. Foe examle typing in "algebra" will give you a lot of hits on solving and learning algebra problems.
You could try www.youtube.com and see if there are any math tutorials there.
I'm a mathematician. If the websites don't help, email me your problem.
