- Summary:
- Employs animation and live photography to present a series of examples demonstrating axioms as statements accepted as true without proof and applies these axioms to addition, subtraction, multiplication, and division. Shows how the root of each equation can be used to check solutions and uses an equal arm balance to illustrate that what is done to one side of an equation must be done to the other. Concludes with a problem the solution of which requires the viewer to select correct axioms.
