For those who like doing “alternate reading” with our programmed texts, this book explains, mostly in words and paragraphs, important concepts of math starting close to the beginning and moving up to algebra concepts such as exponents and the Cartesian coordinate system. It's meant to be useful both for students having trouble in math, and also for those who like math and would like to spend time thinking more about why you do what you do. (For example, why do you invert and multiply when you divide fractions? Why do you start at the left when you're dividing and start at the right when you're multiplying?)
