A video with the old method of "multiplication on sticks" is gaining popularity on the Internet

Recently, a description of an ultra-light and simple multiplication method has appeared on social networks, which, due to its unusual appearance, is called "multiplication on sticks." Its origin is not known for certain, but most often it is associated with ancient Japan or China.

The essence of the method is just in sticks or lines. The original numbers are divided into composite numbers, then the corresponding number of lines is applied to the field. Each digit has its own sector, and the lines of the second number are drawn at an angle to the first. The task is to mark all the intersections of the lines, write out these numbers, which will automatically add up to the solution of the problem. As simple as that.

It is easy to see that the technique is designed for a straightforward perception of information - while there are few dashes, it is easy for the mind to understand them, but look what you get if you try to multiply 9 and 8. Meanwhile, already in ancient times people had to carry out calculations where values ​​were much larger than the number of fingers on your hands.

It is likely that the entire method is someone's sophisticated joke: all references to "multiplication on sticks" are not older than 20 years, that is, the active life of the Internet. The same "Russian method" is described much earlier and in more detail, but here all the thematic articles refer to each other. But one cannot fail to note the positive effect of the widely distributed video - it attracted the attention of people and for some time was interested in real mathematics.
