The golden ratio has been seen in mathematics, architecture, music, natural phenomena…and now sumo wrestling.

We always thought basic math principles were useful, but who knew they could be funny too?
Studies show that only 60 percent of Japanese 20-somethings are able to correctly solve this math problem, compared to a whopping 90 percent 30 years ago.
If a notebook costs 100 yen, 20 yen cheaper than a pencil case, then how much is an eraser?
Students who add and multiply with the numbers in the ‘wrong’ order are getting their answers marked as incorrect? Japanese net users weigh in.
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.
While many Japanese people might not get “American jokes,” they do seem to be enjoying some certain English memes. For example, “The Little Test That Blows Your Mind,” which recently reappeared online, was translated and posted to a Japanese website, garnering over 1,500 comments.
If you’ve already taken the test, you’ll definitely want to see how your answer stacks up against these Japanese commenters. And if you haven’t taken the test yet, be sure to give it a try!
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.
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.
