Negative Positive
Title: this book is not that useful
Review: This book primarily contains two chapters explaining that you canshorten the time and interest you pay on a loan by making additionalpayments regularly or irregularly. The rest of the book is full of tables. the program that came with the book is only an MS-DOS program and only calculates interest paid and the lifetime of a loan based on the input of interest rate, principal, minimum payment, etc....In addition, the editorial review was made in a newsletter distributed by the authors of the book. Of course they like their book.
Is the review positive or negative?
