How do i find the z score

I can solve all the problems with the help of app. I'm very impressed that it can now read handwriting and solve complex problems. Would be a lot better if it also gives answers for trigonometry and other formula based equations.

I would highly recommend it to everyone. My professor is using a very great platform to teach but when it's time to do it on my own I still need a little help. It's been since I graduated high school that I've done any higher level math, so I'm revisiting the basics of algebra.

Very useful for calculus, its such a great app and its very helpful. This app is good for learning and understanding your mistakes in math. Hoping for new updates, even tho its already perfect.
