Ohms law problem

My math teacher always gives us really useless homework that takes hours to do by hand, makes you write down every step and it just takes forever. As a highschool being self taught this app is amazing, because I made my math problem so easy.

Usually with these apps they give you kind of a half answer and when i downloaded this i was expecting to just be able to solve simple highschool equations but this app gives you everything you need, now you do have to pay for the full experience where it explains why and how.
