This book wins the Medal of Honor in the world of math books. No other book or online resource is more useful, beneficial, and practical for everyday use in the real world. This book also put me through college algebra, geometry, and trigonometry and blew the hundred dollar text books out of the water.
Since it is many years since school/univ. I find that I have the need for a "refresher" in maths. This book is IT!!!!
Straightforward, concise and written in simple language, this little gem covers it all. From basic arithmetic through elementary trig, with plenty of examples, tables and illustrations. It's all here. Simplifies those things you have long been afraid of when it comes to numbers. Get it along with the companion application workfook and you'll be set whether you're a tradesman or student.
