Chenier Educational Ent Practical Math Dictionary

This book was written to help those in the trades to learn/remember/find solutions to common and obscure problems that come up in a days work. From reading a tape measure (you'd be surprised how may people really don't know how to use one!) to the trig involved in laying out complicated rafters, to calculating gear ratios - its all in here and more. This is the way math should be taught in schools. Chenier gives the problem, shows every step in finding the solution - (without a calculator!); how to prove the results, then explains how to apply it.The end result is you really understand how to solve the given and similar problems. This has been a lifesaver to many that I have worked with over the years and I will buy several at a time to give to new and seasoned tradesmen alike. I highly recommend it for any school students that have trouble with math. I wish I had it when I was in school. But I've got one now!
