tapintoteenminds.com/japanese... Have you ever seen a quick video on KZitem or Facebook showing the Japanese Multiplication Method? Maybe you saw the one called the Chinese Multiplication Method? In any case, people are astounded when they see what appears to be a simple trick to multiply two-digit by two-digit or even three-digit by three-digit numbers using only a series of parallel and perpendicular lines to yield you a result. Well, this video let's the cat out of the bag that it really isn't a trick at all. There is a lot of conceptual understanding buried in the Japanese or Chinese Multiplication method and it is way more powerful if you understand why it works. Have a look and let me know your thoughts in the comments!
