Multiplying Whole Numbers

In reality, most business problems involve a combination of procedures. For example, invoices, which are a detailed list of goods and services sold by a company, require multiplication of items by the price per item and then addition to reach a total.
From the total, discounts are frequently subtracted or transportation charges are added.

Multiplication of whole numbers is actually a shortcut method for addition. Multiplication is the combination of two whole numbers in which the number of times one is represented is determined by the value of the other. These two whole numbers are known as factors. The answer to a multiplication problem is the product.
