Easy-to-read, fun format. Well structured to build on concepts as presented. One caveat: taking a square root of a negative number IS defined. Early on, dividing by zero is properly presented as "undefined." Unfortunately, in the ROOTS section, the term "undefined" is used to describe taking a square root of a negative number. The biggest example of "defining" a concept is where imaginary numbers came from -- by definition, the square root of -1 is "i" usually represented by a lower-case script letter. One of the best treatments of that in a book catering to this level of a learner was "We'll talk about that later" rather than insetting an absolute that will have to be "unlearned" some time in the future. Not a deal-breaker, as otherwise the book rocks.Was this review helpful? Yes NoThank you for your feedback. Report this reviewThank you, this review has been flagged.
