## A lot of happy people

I used photomath, but it didn't work for some problems, it explains every step so clearly and in detail. This thing is so amazing ¤© Like just take a picture of the equation and it solves it for you :D, i personally, love the solution working out function and also the graphing one.

This app is really good for helping you with your problems and with just 10. Step by step solutions and of course, way cheaper than a tutor, well I guess with the latest update now we have to pay for app plus to see the step by step and that is a big no no.

My teacher assigns homework as extra review for people who need it but takes it as a grade, we are very grateful for you. This app is great, planning to buy the paid version so i am able to show work latter when i progress in college.
