Cool Little Trick for Multiplication

What’s 23 x 33? Here’s a visual way to solve the problem.

Draw 2 lines and then 3 lines to represent 23 and cross them with 3 lines followed by another 3 lines for 33 as in the drawing above. Add up the number of intersections in each corner of the square as if they were columns.

A=6 for the hundreds or 600

C=9 + B=6 is 15 for the tens column or 150

D=9

Add 600+150+9=759.

This new method of addition is all the rage in Japanese who have imported it from India as a new way to teach young children how to break down complex problems into smaller, solvable problems.
