In this video, we will solve systems of equations word problems involving mixtures of alcohol / acid.

In this video, we define rational expression, and find the domain of rational expressions.

In this video, we learn how to add, subtract, multiply, and divide complex numbers. In the dividing portion of this video (7:05), we look at how to use the complex conjugate to rewrite quotients.

In this video, we define and use sigma notation for series.

In this video, we use sigma notation to evaluate series.

In this video, we work out work rates word problems. In the first problem, we see how long it takes to build furniture while working together. In the second problem, we see how long it takes to paint a room when working together.

In this video we will VERIFY identities (see if the identity is true) using the basic trig identities - reciprocal, quotient, and Pythagorean.

How to simplify when you add, subtract, or multiply radical expressions

In this video, we simplify expressions by using the distributive property and combining like terms.
