By using Criss cross multiplication methods, Shakuntala Devi from India did 13 digits by 13 digits multiplication in 28 seconds only which is a world record.
once you learn this method successfully then you can also do 3x3 or 4x4 or 5x5 multiplication or even more,
This will create new perspective on Maths learning. I am sure after learning this method successfully and practicing enough this will create amazing maths power in you.
