Elementary
While the Algebra and Calculus notes here cover material taught in high school they are not intended as high school texts. Instead they are designed for university students who have insufficient high school mathematics for regular first year university mathematics courses or for adults who have forgotten, or would like to revise, basic high school algebra and calculus.
The Adult Education notes take one well beyond high school mathematics, but with very little prerequisite knowledge required. They are designed for the mature adult who has a philosophic bent and is curious to know about the more mysterious mathematical concepts, without getting too bogged down with technicalities.
