Love it or hate it, long-division is a necessary and practical skill to learn. While I certainly don’t use any of my high school calculus in daily life nowadays, I do occasionally whip out a pen and paper to calculate how many cat sushi figures I can buy for my yen’s worth, for instance.

Recently, our minds were blown when we stumbled across a picture that illustrates the ways that people in different countries calculate long-division problems. Which style were you taught to use in school?

One Japanese forum user recently uploaded a picture of what appears to be a page from an elementary school textbook illustrating the various models that people use to compute long-division problems in different countries around the world. Take a look for yourself:


The text in the photo reads, “Let’s compare division styles from around the world,” and asks students to discuss the differences that they see. Starting from the blue box in the upper left-hand corner and moving clockwise, the countries included are Japan, South Korea, India, Brazil, Israel, Netherlands, France, Portugal, Turkey, and Argentina.

As an American, I was taught in elementary school to divide using the same model that is shown for Japan and South Korea. In fact, I had no idea that so many other models existed! Can anyone confirm the actual existence of the other styles?
