A new set of SAT practice questions from the Official SAT Study Guide (page 803) greets Sal and the viewer. Problems 1-7 involve basic algebraic equations, linear equations, and geometric figures.

Problems 7-9 involve exponents, inequalities, and geometric figures (diameter and radius), all of which Sal explores eagerly. After misreading one problem, he takes care to correct his mistake, showing students how important it is to...

Sal demonstrates the methods needed to solve problems 8-10 in this video. He begins his lecture with a more thorough explanation of problem 7 (which he feels he "rushed" in the last video). These problems involve skills such as...

One of Sal's greatest gifts to students in this SAT video series has been his demonstration of word problems. Because he writes out equations while simultaneously reading the information provided, he often arrives at the correct answer...

The problems are getting a little more difficult in this video, which covers problems 13-16 on page 778, but Sal is still easy to understand. He demonstrates various strategies for solving algebraic expressions and problems involving...

Simplify the process of simplifying expressions. Scholars use the properties of exponents to simplify algebraic expressions. A brief video takes viewers through the process of using the product, quotient, and power rules to rewrite...

Divide and conquer the quotient rule for exponents. A short video shows how to simplify exponential expressions using the quotient rule. The narrator works through several examples on the topic.

Powers of 10 are about moving the decimal around. The instructor illustrates how to move the decimal when it's ten percent or it's one percent. Once you understand this procedure you can do the mental math, in your head of course!

This presentation covers the basic definition of exponents, raising something to the exponent zero, simplifying negative exponents, multipling powers of the same base, and dividing powers with the same base. The presenter then...

The laws of exponents are explained in this video. Topics include raising something to the zero power, rewriting an expression that has a negative number as an exponent, multiplying powers with the same base, raising a power to a...

This video starts with the basics and shows how to simplify monomials. First, it defines what a monomial is, then gives examples of monomials, evaluates integers raised to a power, and multiplies monomials with the same base....

The basic rules of exponents are covered here. After defining an exponent, the presentation covers the following rules and shows examples of multiplying powers with the same base, simplifying monomials that are multiplied, raising a...

Third example's the charm. To learn about simplifying expressions, young mathematicians watch a short video that shows how to simplify an algebraic expression using several properties of exponents.
