Since the time of the Babylonians, variables and equations have played a central role in mathematics. But despite its ancient origins, algebra remains a tough subject for many of today's students and it's wise to provide them with powerful visual aids. In this program, internationally acclaimed mathematics educator Dr. Monica Neagoy traces the history and evolution of algebra and explores the two principal equations encountered in introductory algebra...
14) Inequalities
Language
English
Description
Minor steps like reversing the "less than" or "greater than" sign might look simple, but when students first try to grasp the strange world of inequalities, they often feel overwhelmed. That's a problem that needs addressing, since inequalities are not only fundamental building blocks of algebra, they're also used in a wide variety of professional and industrial applications. In this program, internationally acclaimed mathematics educator Dr. Monica...

Description
Environmentalists, meteorologists, economists, and people in many other disciplines have always been interested in the dynamics of variables, or quantities that change-for example, the number of polar bears that inhabit a certain region during the summer, or the number of tickets sold during a movie's first weekend in theaters. Functions are indispensible to that kind of sampling since they represent relationships between variable quantities. Hosted...
