Corporations and small businesses need statistics and accounting principles related to profit and cost analysis. If you are in college and you already have a firm understanding of such business math principles, you might want to take the DSST Business Mathematics exam.
The DSST Business Mathematics exam covers the following topics:

• Number sense
• Algebraic Concepts
• Statistics
• Financial Mathematics. The Business Applications section comprises 50% of the exam questions, including topics such as index numbers, interest, depreciation, taxes, cost calculations, investment performance measures, and cost minimization, among others.

The best way to study for the DSST Business Mathematics exam is to use a DSST study guide, which will have sample questions and other helpful hints specifically geared for the DSST Business Mathematics exam.
You may also want to check out some introductory business math textbooks. It may be helpful to compare the study guide outline with the chapter titles from a textbook, and review the material that overlaps.
