This is my attempt to introduce the mystery and wonder of irrational numbers and their link to our naive notion of cause and effect. The followers of Pythagoras believed: "All is number"! Have you ever truly wondered what they meant?

In this video I will show you how to use a number line. You will learn how to find negative and positive numbers on the number line. Also, I will show you how to watch out for different "scales" used on the number line.

Review the process of long division of polynomials with an example problem.

Sample world problem with solution described by an inequality. This problem is from a discrete math class involving a school field trip.

Solving for the dimension of a strip cut from a 1 mi X 2 mi rectangular area to leave 0.75 sq miles remaining.

Multiply first, outer, inner, then last terms.

This is one of my favorite algebra tricks. I use it now to showcase my tutoring style.

This video expands on the idea of logs and shows how to graph logarithms.

When asked to factor a quadratic equation such as 2x^2 - 7x -15, many students are uncomfortable with the guess and check method. I created this video to describe a 7 step method that requires NO GUESSING.

This is a lesson on solving general cubic polynomials by radicals. In this part, I discuss solving non-factorable cubics using Cardano's method. I finish up by briefly discussing a special situation called "Casus Irreducibilis".

This is a lesson on solving general cubic polynomials by radicals. In this part, I discuss solving factorable cubics. I end the discussion by looking at the cube-roots of unity.

Doing a little bit of Geometry and Algebra in the clip!
