PhotoMath


PhotoMath, by MicroBlink Ltd., is a neat little utility available from the iOS App Store, and Android Play Store, that can make solving elementary Math homework less of a chore. Besides giving the answer outright, it provides a detailed step-by-step procedure for arriving at the answer.

Try it while the following equation is displayed on a second screen

2x^2+3=11

It does have its limitations though. An equation such as the following is currently unsolvable

\frac{1}{1-\frac{1}{1+\frac{1}{1-\frac{1}{x}}}}=3

Wolfram Alpha makes short work of that equation when you query it using its \LaTeX representation.
