Math-solving phone app is the quickest way to self-study, skip homework, and/or fail your tests

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.

Japanese elementary school teachers may tell you “5 x 100 = 500” is wrong

Here’s an elementary school math question for you all:
Apples are sold for 100 yen each. If you buy 5 what is the total amount?

If you said “5 × 100 = 500” then I’m sorry but you just flunked second grade math in Japan… if there were only one question all year.

The reason is an old teaching method that is employed in elementary and middle schools throughout the country. It’s also a method that many, such as a blogger by the name of Uncorrelated, want stopped as it leads to strange logic where six times seven does not always equal 42 and five times 100 might not equal 500.

Tokyo University Makes Calculator Using Robot, What It Lacks in Usefulness It Makes Up for in Cuteness

Japan is well known for both its love and skill of robots.  Free of the terminator-induced prejudices of western cultures, they have blazed the way for robotic tour guides, waitresses, fish, singers, hairdressers, waste baskets, cyclists, rock-paper-scissors players, cockroaches, butts…

With so many robots, it’s hard to come up with an original one.  But they are still out there. Tokyo University’s Center for the Study of Robotics came up with Denta-kun, the calculator using robot.  Just to make it clear, the robot does not calculate. It just uses a calculator.
