I think we can all agree that math is a pretty handy thing to understand, right? A basic concept of things like fractions and algebraic equivalents is what keeps us from getting taken advantage of by con men who make such tempting offers as trading two of their shiny monies (or even three!) for our one paper money when the latter is actually of greater value.
Still, basic math is all about following the proper procedures to arrive at the one true solution, which is why you don’t get partial credit for having the wrong answer on your math assignment just because you took a novel approach and wrote the numbers with nice penmanship. As such, you can program a machine to spit out the answer in a fraction of a second, and with a new smartphone app, all you have to do is snap a picture of the math problem, and let the app take over from there.
