Architecture - Practical math

Is anyone here familiar with a book called "Chenier's Practical Math Dictionary"? I just saw it in a catalog, it sounds like a good book to keep in the truck for the typical job geometry I run into now and then. I don't need a "math" book, just one with solutions to construction type problems, like layout, triangle formulas, circle or radius formulas, the kind of stuff you don't need everyday, but when you need it, you need it, cause it's a heck of a lot quicker/cheaper than trail and error. Anyone got any other suggestions? Thanks.

I use Ugly's, since it has an array of mathematical formulae, as well as electrical data, motor data, conduit take up measurements, which directly apply to the trades. A general math book may be a little too voluminous for everyday use. But, to each his own, right?!

Ugly's is a great book.

Or one of the very handy "Project Calc" calculators that can calculate brick, block, plywood/drywall, paint, concrete, squaring measurements, etc.

I was looking at the calculators and was unsure which one to get. Do you have a favorite? The most common thing I find myself doing is dividing lengths by a number, ie. 6'&3/16" div by 5.

The Project Calc ($20) is adequate for most home projects, and will do fractionals.
