How to subtract linear expressions

Helped me very much on all math, i need math to be dumbed down for me to the simplest explanation and this app does exactly that, used this several times, and can officially say it's a lifesaver, many times I've had math problems that are too specific for the internet to explain, and this app can do it! The camera function works for neat handwriting too, not just printed out math.

By far the best math solving app if you are doing calculus. Math app helped me learn more about Trigonometry than the professor. I think it could be explained a little bit better, it really means a lot.

I'm in college algebra and its the perfect aid for any problem solving. This is a really good app. It reads the problems correct pretty much every time, i wish the why? Was free though and not locked behind the pay wall. Thank you god. It can answer many problems and can even have a conversation with you - just go to the variable section and try typing in "hi".
