Mathpix is an iOS app that can do something pretty sophisticated: it takes a photo of your handwritten maths problem, scans it, and solves it for you with step by step solutions. Take a look:
I tried it out on a few math questions on my own, and it amazingly really works!
Most of the time it works for very clearly defined problems, but sometimes it fails to scan properly or doesn’t understand the question.
In any case, this can be a good way for students to easily check their work when they don’t have access to maths tuition or when they are studying at home. One other good thing is that it shows the step by step working for some problems, which can help students check not only the answer, but their working as well.
