To me it was an eye opener to see how financial math can be used to analyze most financial functions such as home mortgages, insurance policies, mutual fund rates of return, and consumer loans, as an aid in making important and informed financial decisions.
The book is easy to understand and there are many examples to demonstrate the applications. Also it is a good book for self teaching with many examples to work with answers provided to check results.
However, it is necessary to understand basic algebra and to have the ability to follow the examples that are quite comprehensive. The author shows how to use a Hewlett-Packard 12C financial calculator to perform the math. For those who can do this it will be quite rewarding. For example there is a method shown on how to easily save a significant amount of interest on one's home mortgage as well as check the progress of a variable interest rate loan if you have one. The book must be studied and the problems worked to get the full benefit. It cannot be read like a novel.
