PhotoMath is a genius new app that solves maths equations instantly, just by pointing your phone camera at them.

After PhotoMath has solved the equation it will show you how it can be worked out. Although my guess is that most users will skip that part.

This is a math teachers nightmare! Although fortunatley for them, the app wont be availble until 2015.
