Zero to Infinity: A History of Numbers

An Intuitive Sojourn into Arithmetic (1x12)

Uitzenddatum: Jan 01, 2007

We begin with a historical overview of addition, subtraction, multiplication, division, and exponentiation, in the course of which we'll prove why a negative number times a negative number equals a positive number. We'll revisit Euclid's Five Common Notions (having learned in Lecture 11 that one of these notions is not always true), and we'll see what happens when we raise a number to a fractional or irrational power.
