Japanese multiplication method lines. As you ll see below the japanese multiplication is simply skipping the step of drawing out the base 10 blocks by having you focus on the intersection of the base 10 blocks or the sticks lines. Draw sets of parallel lines representing each digit of the first number to be multiplied. On the left corner put a curved line through the wide spot with no points. Draw vertical lines with respective to the numbers 2 3 1 from 231.
Steps in brief for japanese multiplication of three digits multiplication. Put dots where each line crosses another line. In the japanese multiplication method we are able to complete a multiplication problem by merely drawing a few lines and counting the points of intersections. Let s take 12 32 as our example.
