What mathematics is covered on the AMC 10?
One way to explain what is on the AMC 10 contest is to say what it excludes (that is still fair to put on the AMC 12). What are excluded are trigonometry, advanced algebra, and formal geometry. Another way to explain what is on the AMC 10 is to say that it assumes elementary algebra; basic geometry knowledge including the Pythagorean theorem, area and volume formulas; elementary number theory, and elementary probability.
