Stan shows how to work with Linear Inequalities in this lesson, learning to graph and solve them (using addition and subtraction). He also includes "You Try It" exercises to test your understanding of the concepts. (16:57)

We learned how to solve one-step equations. Now we solve multi-step equations. We learn that Reverse Order of Operations will tell us which step to perform. (13:32)

In this lesson we continue our discussion of exponents, explain zero and negative exponents, and simplify some algebraic expressions involving exponents. (20:52) by Stan Lisle

There are three ways to solve a system of linear equations. In this lesson, we talk about two of these methods: Solving a Systems of Equations using Substitution; and Solving a System using Addition or Subtraction. (15:37)

This lesson explains exponential growth: does a data set represents exponential growth; how to graph that data set; and how to create an equation that describes the relationship.

Scientific notation is used to express very large and very small numbers. In this lesson we learn how to write and interpret numbers in scientific notation. (19:10)

Every game has some rules. The exponential game is no exception. In this lesson we learn rules for multiplication with exponential expressions. (12:56)

People work hard on educational categories, and we want to encourage them to make more!

Profanity (curse words), sexually suggestive remarks, and other such obviously inappropriate comments
will be deleted immediately, and are grounds for immediate expulsion. Remember, children use this website.
