To multiply two numbers by hand takes a few steps but it's something we're taught in school. When dealing with big numbers, really big numbers, we need to a quicker way to do things.

An algorithm is a sequence of logically connected mathematical steps that solve a problem. For example, an algorithm to add three numbers can have two steps: add the first two numbers in the first ...
