Mathway

I could have used this in High School. Not only does it give you the answer, but it writes out how to get there so you can "show your teacher your work." ;)

I absolutely would have abused this in high school and college. Unfortunately we don't live in an ideal world @ghobs91

This is intuitive. I've mostly been using Wolfram|Alpha to help solve math problems.

In an ideal world, students would use this to better understand the math problems they're solving if they get stuck. In reality, most will probably use things like this and wolfram alpha to do their hw for them, as @rrhoover is implying :). Maybe I'm just overly cynical.

we need more math literate kids coming into this world not less lol .. but probably would have used this in school
