Technology has become an indispensable aspect of most mathematics education. This is a BLACK-AND-WHITE edition of our full-color textbook; it contains the same abundance of graphics, algorithms, and assignments to introduce Sage, a free, open-source computer algebra system, and to reinforce important mathematical ideas of undergraduate mathematics, including some that a transitioning student will not yet have seen. This book should be useful for any situation where an individual is moving from "high school" mathematics, in which we include basic calculus, to "university" mathematics, which includes intermediate calculus and a lot of stuff besides, and is willing to experiment with a computer. You miss out on the color, but it costs less.
