Find the exact value of the expression calculator

This application really helped me in solving my problems and clearing my doubts the only thing this application does not support is trigonometry which is the most important chapter as a student.

I just downloaded this app because trash photomath all it did was make my phone crash but this have not made my phone crash and lag and my phone is new just got it yesterday, it's a very useful app, it can make a lot of very difficult equations very fast, this is the main reason I am passing my Honors Algebra 2 Class, not because I use it to cheat, but because I use it to figure out how to do the problems and then use that method to actually do the problems without This app.

This app is so much fun because it helps me with a lot of math problems ’¯’¯. It changed my damn life, helps my daughter with math when I'm not home, once done boom you have your answer.
