Business Math

Course Description: This course is built from this business mathematics course. It will make this course easier to have completed consumer math since there is some overlap in topics, but it is not required.

This course uses text and video to provide a basic understanding of business problems in mathematical terms and how to solve those problems. Topics include the application of basic mathematics to business and industry using ratios, functions and graphs, simple and compound interest, financial instruments and discounting, annuities, mortgages, loans, and leases. Also included is cash-flow analysis applying rates of return, net present value, and payback.

The Texas Instruments BA II Plus is recommended, and will be used in solving problems. Here is a free version available as an app.
