RePost from iDevice in the Mountains: PhotMath

Photomath - Mobile Device Solves Math Problems Posted: 18 Dec 2014 04:01 PM PST   I remember teaching Advanced Math in High School, and often times I would randomly write down a few Algebra problems for students to solve.  However, I also needed to solve them to generate a key.  Even though that isn't a huge hurdle, there is an app for that. Photomath, available for most any mobile device.  Yes, using the camera you get the problem into your viewfinder, and the expression is either simplified or the equation is solved.  You don't even have to key in the problem.   You can examine the steps taken to solve the problem.   The app also contains a history of all the equations or expressions you've scanned. This would be a nice tool for students to use in order to check that they complete practice problems correctly.  At this time the app can simplify arithmetic expressions, interpret fractions, decimals, powers, and roots, and solve linear equations.  It can't comprehend higher level math like Trigonometry or Calculus, yet.  Hopefully in the future, as the app was released just a couple months ago.
