Multiplication: different methods
Filed in Maths on September 26th 05 .
The way we do long multiplication (and long division for that matter) has more to do with the limitations of printing in the 1500s than anything rational.
A couple of alternatives include
- Lattice or Gelosia multiplication
- Russian multiplication
The links above are from the excellent Ask Dr Math page, and I especially like the Russian multiplication page that explains why the method works.
