What is the difference between the arithmetic 3+5 = 5+3 and the algebraic a+b = b+c? One is a specific fact, another is a pattern valid in a multitude of situations. While arithmetic may hint at some regularities,...

This is a comprehensive bibliography on axiomatic set theories which have a universal set. (Zermelo-Fraenkel set theory, the most widely studied set theory, does not have a universal set.) This field presently includes...

Written by Tony R. Kuphaldt, this chapter of All About Circuit's fourth volume on Digital circuits examines Boolean algebra and logic. The chapter has a helpful introduction that discusses the difference between real...

This simulation-based laboratory activity allows the student to practice several types of graphs and explore the types of information that we can collect from graphs. Coverage include exploration of linear, non-linear...

This lesson from Illuminations asks students to look at different classes of polynomial functions by exploring the graphs of the functions. Students should already have a grasp of linear functions, quadratic functions,...
