Summary

Algebra starts with the natural and simple problem of trying to Polynumbers are extensions of numbers, but with a richer Angles don't make sense in the rational number system. The proper notion of the separation of two lines is the `spread' between ... We discuss parallel and perpendicular lines, and basic notions relating to triangles, including the notion of a side and a vertex of a ... We consider three methods, or algorithms, for finding the square root of a natural number we know to be a square. One is trial and ... We define addition and multiplication of fraction to parallel the operations for natural number quotients. A crucial step is to check ... This video introduces the graphs of polynumbers of polynomials. We plot both integer and rational points, and use straightedge ... This video continues to discuss difficulties with angles. It takes a historical approach, and emphasizes that with angles, ... We begin the important task of defining the fundamental objects of modern algebra. First we review different roles played by ... We review the standard formulas for
