Williams’ formulae, factors and accurate shorts were first used to help his students, but then the author saw that many professional construction workers also could not make simple calculations in the field. )-- Author, teacher and contractor Kenneth Williams, Sr., announced today the release of Applying Mathematics to Construction, Carpentry Mathematics and Estimating, published by Outskirts Press. Williams’ handy guide for both students and professionals diminishes the need for cumbersome measuring devices and calculators by teaching simple, easy formulae for quickly figuring out construction math problems and material estimation costs. Realizing that the use of calculators and measuring devices can also hamper one’s ability to think creatively and quickly on the spot, Williams put together these clever mental calculation tips to help students, instructors and general contractors. The first section of Applying Mathematics to Construction shows how to make calculations without the use of external tools and contains such innovative tricks as his conversion of a large number of feet to inches in seconds, mentally. Section two covers how materials are measured and sold and, like the first section, offers one simple formula after another to make on the spot calculations simply and immediately.
