How convenient that all the examples use digits in the 1-3 range. This looks painful for normal numbers with a mix of large and small digits. This method always made more sense to me: http://www.ehow.com/video_12244670_solve-multiplication-prob... as it combines the idea of the diagonal lines in the "japanese" method with the mnemonics of the [1-9]x[1-9] multiplication tables that everyone should also learn. |
