After a short review of exponents, Sal incorporates exponent properties into his sample problems. This video is a great resource for those who need Sal's steady pace of instruction and the challenge of more complicated problems.

PEMDAS is not all that it is cracked up to be. The short video provides an argument that the order of operations may not be instructionally sound. The presentation shows that understanding the concepts and properties of mathematics...

This video focuses on a series of problems involving exponent properties. Sal demonstrates rational expressions, simplifying fractions, and manipulating algebraic equations using exponents and division.

An instructional video in which six example problems are solved. Topics include: changing a conic equation to standard form in order to identify and describe it; using properties of logarithms to simplify expressions and solve equations;...
