Mrs. Holton presents a humorous, accurate and well-disciplined look at much of what is ""new"" in mathematics. The reading level is such that senior high school students would benefit most from the text. (Perhaps even parents of children of the ""new math"" could gain insight.) Beginning with a disarmingly simple introduction to the concept of number system base, the text moves rapidly and interestingly along, covering what is conventionally considered algebra (factoring x's and y's) on the way to topics like real and complex numbers, modular algebra, matrices, sets and Boolean logic. A hearty serving, in fact, and almost to be considered a text book; but a very readable and enjoyable one albeit.
