Query: Great book for a refresher course

This is the book used to teach shop math at out local collage. It's the perfect book for the person going into the maching field, or just needing a refresher to knock some of the cobwebs loose from high school math. Has a lot of hands on type problems that are encountered every day in a maching shop. Also has several useful charts in the back.
