Chinese Multiplication (Lattice Method

CodyLayder

This video is mostly a straight up guide.

Have any of you heard of this before now, because I certainly hadn't.

Some further reading

Wiki: https://en.wikipedia.org/wiki/Lattice_multiplication

Further Guide: http://www.education.vic.gov.au/school/teachers/teachingresources/discipline/maths/continuum/Pages/latticemulti.aspx This one says that this method comes from Italy and was introduced by Fibonacci! Despite it being called frequently the "Chinese Window" style of multiplication, so some conflicting theories.

More conflicting backgroud: http://rationalmathed.blogspot.co.uk/2007/10/who-invented-lattice-multiplication.html So bits of this text say it originated from India?

Please tell if I'm living in the Stone Age with this, since I've only just discovered it.

I learned this method in 4th grade! It's been my preferred way to multiply since.
