Basic Construction Math--Part 1 (approx. 60 mm.)
This lecture reviews arithmetic functions, fractions, decimals, percentages, powers, and roots. It is not available in audio format because many of the calculations are done on a chalkboard.
Part 1 and Part 2 are completely independent lectures. If a student wants to review math down to the basics, he or she should start with Part 1. If the student has some ability in math but wants to review the more advanced calculations, he or she should start with Part 2.
