In this article we introduce the free educational mathematics software GeoGebra. This open source tool extends concepts of dynamic geometry to the fields of algebra and calculus.

This is a Developer's Area article that describes how to use a Java applet called LiveGraphics3D to speed up the process of creating interactive graphics by removing the need to create a graphics engine in Java, Flash, or other programming languages.

This Editor's Note discusses best practices for writing web-based expository mathematics.

This article unifies four numerical procedures for solving nonlinear equations: the regula falsi, Newton--Raphson, secant, and Steffensen methods.

This article argues for pedagogical reasons that the dot and cross products should be defined by their geometric properties, from which algebraic representations can be derived, rather than the other way around.

This article uses interactive mathlets to explore various methods of determining the winner of a three party election. Methods of constructing paradoxical examples are also given.

Poems sometimes have interesting connections to mathematics, either because of mathematical imagery in the poem or because of mathematics in the structure of the poem (word or syllable counts or shape). This article explores some of these connections

In this article, we use on-line resources and computational tools to approximate the volume of the space occupied by each planet as it orbits the Sun.
