Abstract
The video shows what it claims is a new method of multiplying. It is simple, somewhat strange, but it always seems to work. It starts by showing us how to multiply 21 by 13. To do this we have to draw two horizontal lines, which represent the number of tens (2) in the first number. Below we draw a single line that represents the number of units (1) it contains. Then we draw the second number using vertical lines: one on the left for the number of tens (1), and three on the right for the number of units (3).
