Best-selling author Nigel Cook's new fourth edition of "Introductory Mathematics" is a complete "prep-math" book. Clear and easy-to-understand, this book employs an integrated approach, reinforcing all math topics to show the value of math as a tool, enabling readers to retain all information. Beginning with fractions and decimal numbers and proceeding on to build a solid foundation in exponents, the metric system, algebra, trigonometry, logarithms, graphs, and binary math, this easy-to-understand book will give readers the math skills needed for their careers. A valuable reference book for those in the technical trades, including electricians, automotive mechanics, printing employees, landscapers, surveyors, machinists, carpenters, food service employees, manufacturers, welders, plumbers, masons, drafters, and more.
As far as math textbooks go, this is clear and understandable. The author describes real and mostly practical applications, so you're not learning anything without reason. The simple language makes me feel like relearning this stuff is no big deal, though I'm about 12 years rusty.
HOWEVER. This book is riddled with typos, which is a shame for someone like me without a lot of math confidence. Also, the very light gray text describing steps in a problem is hard to read. I think this was originally designed in color and printed in black and white without any followup check.
So, basically, proofreading. This math book needs proofreading.
