Have you every had trouble on a math problem? well this will help. this was used long ago and its simple. i'm sorry, i have sloppy writing. and i took pics with my dsi cuz i couldn't find my camera.
Step 1: Create a Box
create a box with with smaller squares in it by the digits... so like 8675 times 45 so its 4 digits by 2 digits then put lines through them like pic# 2
then put the numbers on the top and the left sides of the box.
so now you multiply any number that intersect with the row and coloumn
then just add
then you see that the numbers are in order from the line so its 2426508638
so 560913 x 4326=2426508638
