2. Objectives  Describe mathematical, logical, and comparison operators.  Use arithmetic, logical, and comparison operators to create formulas and evaluate conditions.

3. 3 Using Conditional Expressions  What Are Conditional Expressions?  How to Use Arithmetic Operators  How to Use Comparison Operators  How to Use Logical Operators  How to Combine Comparison and Logical Operators

4. Using Conditional Expressions  When you write applications in Microsoft Visual Basic.NET, you need to write expressions that the computer can evaluate. Expressions that evaluate to True or False are called conditional expressions. This lesson explains how to build conditional expressions by using basic arithmetic, comparison, and logical operators. 4
