I've seen the future and it is math less and it is awesome and it is this PhotoMath app that solves math problems just by pointing your phone's camera at them. It's like a cross between a text reading camera, a supremely sophisticated calculator and well, the future. Point and solve and never do math again.
From the video below, it looks like it works pretty great (the app won't be available until 2015 though, the year true future stuff happens according to BTTF). PhotoMath explains:
PhotoMath reads and solves mathematical expressions by using the camera of your mobile device in real time. It makes math easy and simple by educating users how to solve math problems.
After the math problem is instantly read and solved, the app will show you how the answer was reached too. So if you still want to learn math, the app can serve as an immensely helpful teaching tool for arithmetic expressions, fractions and decimals, powers and roots and simple linear equations. The app developers say more is coming too.
But if you're like me, you can't wait for the time machine to be invented in the future so that you can go back into time to tell your high school self to not bother learning math because we've seen the future and it is math less.
