This College Algebra text will cover a combination of classical algebra and analytic geometry, with an introduction to the transcendental exponential and logarithmic functions. If mathematics is the language of science, then algebra is the grammar of that language. Like grammar, algebra provides a structure to mathematical notation, in addition to its uses in problem solving and its ability to change the appearance of an expression without changing the value.

This introductory, algebra-based, two-semester college physics book is grounded with real-world examples, illustrations, and explanations to help students grasp key, fundamental physics concepts. This online, fully editable and customizable title includes learning objectives, concept questions, links to labs and simulations, and ample practice opportunities to solve traditional physics application problems.

Trade benefits both agents when each specializes in what they have a comparative advantage in producing and trading with another agent who has a comparative advantage in something else. The gains from trade occur based on comparative advantage, not absolute advantage. Created by Sal Khan.

When two agents have differing opportunity costs, there is potential for both of the to benefit if they specialize in what they each have comparative advantage in. This video explores how two parties can get better outcomes by specializing in their comparative advantage and trading. Created by Sal Khan.

In this video we work through an example of a question like you might see on an AP microeconomics or AP Macroeconomics exam determining who has comparative advantage in producing a good using data from a table. Topics include how to calculate opportunity costs and determine who has comparative advantage based on opportunity cost.

An interesting case of price elasticity of demand is a demand curve with a constant unit elasticity. Explore what such a demand curve would look like in this video. Created by Sal Khan.

In this video, we introduce the concept of consumer surplus as the difference between marginal benefit and price paid. Created by Sal Khan.

This resource includes online homework and quizzes, lecture notes for instructors (some with guided note packets or student versions), sample syllabi, sample schedules, and sample exams used in a corequisite College Algebra course, where students are enrolled in both Intermediate and College Algebra simultaneously. All of the resources can be used for a stand alone College Algebra course, with minor editing.  

Learn about how firms determine the optimal combination of capital and labor in this video.

Price of one good impacting quantity demanded of another. Created by Sal Khan.

To get a better intuition about how much a consumer values a good in a market, we think of demand as a marginal benefit curve. In this video we look at the demand curve from a marginal benefit framework. Created by Sal Khan.
