Boolean Expressions in Visual Basic

A Boolean expression is one that can be evaluated as true or false. A Boolean expression can use relational operators such as < for less than, > for greater than, = for equal, and the logical operators AND and OR. In this lesson we will use the If and optional Else statements to decide which statements to execute.
