Using practical examples and mathematical formulas, the tutorial explains how to calculate the interest rate, how to use the future value formula, how to calculate how much contracts are worth based on investment rates, what compound interest is, and how to calculate the value of any asset. It also looks at the distinction between value and price and how both are determined. It emphasizes that wealth does not depend on how much we paid for something but on how much money it is going to produce in the future and how the value of an asset does not depend on its face value but on the income you expect to get from it in the future. Quotes and examples from the Bible, philosophers and economists are included throughout the text so students understand that interest is something that has been around for a long time, even before money existed.
