# Mathematical Interest Theory: Second Edition

Share this page
*Leslie Jane Federer Vaaler; James W. Daniel*

MAA Press: An Imprint of the American Mathematical Society

Mathematical Interest Theory gives an
introduction of how investments grow over time. This is done in a
mathematically precise manner. The emphasis is on practical
applications that give the reader a concrete understanding of why the
various relationships should be true. Among the modern financial
topics introduced are: arbitrage, options, futures, and swaps. The
content of the book, along with an understanding of probability, will
provide a solid foundation for readers embarking on actuarial
careers. On the other hand, Mathematical Interest Theory is written for
anyone who has a strong high-school algebra background and is
interested in being an informed borrower or investor. The content is
suitable for a mid-level or upper-level undergraduate course or a
beginning graduate course.

Mathematical Interest Theory includes more
than 240 carefully worked examples. There are over 430 problems, and
numerical answers are included in an appendix. A companion student
solution manual has detailed solutions to the odd-numbered
problems. Most of the examples involve computation, and detailed
instruction is provided on how to the Texas Instruments BA II Plus and
BA II Plus Professional calculators can be used to efficiently solve
the problems. This is important for readers wishing to pass the
SOA/CAS joint financial mathematics exam FM/2. However, this part of
the book can be skipped without disturbing the flow of the
exposition.

#### Reviews & Endorsements

This is an excellent book on interest theory, one of the four book recognized by the Society of Actuaries and Casualty Acruarial Society as a basis of study for the interest theory component of their joint FInancial Mathematics (FM) exam. What I particularly like about Mathematical Interest Theory is that many problems are intrinsically multi-stepped requiring use of several core functions. By providing a multitude of superior problems, the authors are able to familiarize the student not only with core actuarial function, but also develop their skills in studying the interaction between these functions and real-world problems.

-- Russell Jay Hendel, UMAP Journal

Students pursuing an actuarial career as well as those seeking a mathematically based finances course stand to benefit from this informative, up-to-date, and above all, skillfully written treatise. Instructors and students of interest theory owe Daniel and Vaaler a debt of gratitude for their fine efforts.

-- Susan Staples, Texas Christian University

We use the Vaaler and Daniel text as our primary learning resource for actuarial science majors as they prepare for the SOA FM/CAS2 financial mathematics exam. Each concept is followed by several illustrative and detailed examples that help students master the big ideas in interest theory.

-- Mark Maxwell, Director of Actuarial Science, Robert Morris University
