MATH FOR NDT MODULE

This math course provides refresher training in two parts: general math and NDI math. The general math section includes information on: how to use the Windows calculator, whole numbers, fractions, decimal fractions and percentages.

More advanced lessons include: powers and roots, logarithms, scientific notation, trigonometry and complex numbers.

The lessons in the NDI math section contain many of the formulas that will be applied to such testing methods as: magnetic particle, eddy current, ultrasonic and radiography.

Cost: $19.00 for a 3 month license
