Japanese method is one of the easiest method of multiplication where we draw lines instead of numbers for multiplication we get result without doing calculation.

Japanese multiplication table. It is interesting and very easy way of multiplication where we get our answer by drawing lines only. Each cluster of intersections corresponds to one of the four smaller products that go into multiplying two numbers for instance the left cluster 3 1 is what gets you the 300 or 3 hundreds. You re right i m talking about an array. Here is an interesting method to visualize multiplication that reduces it to simple counting.

When we say 3 times 2 that is the same as saying 3 groups of 2 and we can show these three groups as 3 rows and 2 columns or 3 columns and two rows. This method is applicable for 2 digits 3 digits more digits also. The number of points of intersection near each vertex of the diamond are then counted in a certain order to obtain the solution. Here s how the trick works.

First pick a multiplication problem. Youtuber mindyourdecisions has an excellent explanatory video so to follow along with their example we ll go with 12 x 13. The japanese multiplication method is really just a visual way of representing those four steps. The japanese multiplication method is an algorithm for multiplying two large numbers by representing both numbers by a group of lines that form a diamond pattern.
