Who this book is for
I don't assume much in terms of mathematical training. A general high school study of math is all you need and even then, I include appendices to review subjects such as trigonometry if you need it. The most important prerequisite is an enthusiasm for quantum computing.
I'll quickly say this book is not for graduate students, mathematicians, physicists, and rocket scientists in general. You probably know all this stuff already. But it might show you a new way to teach it.
