Well if you need help in math or have hw but you're just lazy here's a option.
Mathway.com
Gives you the answer to damn near every problem . And if you have premium it gives you steps to every problem.
Has a iOS app as well.
Premium cost 20 bucks a month (I pay for it because I hate pre-calculus).
If you want my login it's only 10 bucks (one time payment).
