Here's my review for this hunt :

Pros:

• PhotoMath is an app that can solve math problems by just pointing your camera to them. The app works very similarly to QR readers, and shows you the solution for the problem in seconds.
• it lets you see a complete transcription of the step by step operation followed to reach the solution. Instead of just showing you the result and nothing else, PhotoMath lets you see every step before the solution.
• PhotoMath is a good math application that lets you solve problems in seconds

Cons :

• No cons as it is very helpful.
