Math Skills: Arithmetic with Introductory Algebra and Geometry has been written for students who need to acquire a better understanding of and facility with arithmetic and need an introduction to algebra and geometry.
The text has enough explanations, real-life examples, solved problems, exercises, tests, and review material to meet the needs of both individualized (lab based) and lecture formats.
The seventh edition also offers the following:
- a non-threatening format that encourages the student to work in the text itself, but leaves the explanations and examples intact even if the exercise sets are removed.
- explanations of the "how" and "why" of developmental mathematics that are concise, readable, and contain many examples and solved problems.
- a good collection of application problems that use real-life data and situations from today's world.
- over 4150 problems contained in Set A and Set B exercises, pretests, reviews, practice tests, unit exams, and a final exam that have answers and selected solutions in the Answer Section.
- sections on conversions with mixed units and divisibility by primes have been added and the sections on reading whole numbers, reading measuring devices, statistical graphs, and the mean and median have been substantially revised.
