This book is an essential tool for corporate finance classes. While the textbook that I used, "Corporate Finance" by Stephen Ross, Westerfield and Jaffe was clear and concise, it did not give any instructions on solving the problems in any way except algebraically. Calculators are an essential tool and if you need any help in connecting those formulas to calculator inputs, this is your guide.
The book is short, but sweet. It includes instructions and line by line inputs for HP 10BII and two other basic models.
You learn how to calculate the basics of NPV, Bonds & Stocks, Mortgages, and Statistics using your particular brand of calculator.
The book is an excellent value for the money!
