Math For Craftsmen

Some level of applied math is necessary to excel in any trade. This math course is a prerequisite for all programs at e-VOTECH and provides the foundation for success in your chosen trade.

Can you calculate the size container needed to hold 4.5 gallons of fresh water? What is the volume difference between water at 35 degrees F and 186 degrees F? These are common knowledge points needed for gaining certification as a Journeyman plumber. How do you convert decimals to fractions? This is a common knowledge point for woodworkers and welders alike. In the electrical trades, practitioners need to understand how to calculate power for a given voltage or understand antenna design for a given radio frequency.

This pre-requisite course covers the basic math behind these questions and prepares you for the trade-specific math you’ll learn during the rest of your program.
