Statements 
Expressions 
Operands and Operators
You can verbalize this hierarchy like this: "Programs consist of one or more statements. Statements consist of one or more expressions. Expressions consist of one or more operands in conjunction with one or more operators." Therefore, to write a program you must understand operands and operators. We begin our journey into the innards of C# by learning about operands and operators.

In Chapter 3 you wrote a program that used two variables to store the information that was entered by the user. The program was designed to divide the first number by the second number. Suppose the user typed in 10 for the first number and 6 for the second. You've been doing this kind of math since you were in grade school. We can write the process of dividing 10 by 6 as:
10 / 6
