## Boolean Overview

Understanding a Boolean formula.

### Creating a Boolean Formula

Boolean operators are used to create conditions that require a logical relationship between two or more values. Conditions that use Boolean operators are called Boolean expressions.

• A and B means that both A and B must be true for the condition to be satisfied (to return a True value).

• A or B means that either A or B (or both) must be true for the condition to be satisfied (to return a True value).

### Examples of Boolean Operators

Several useful examples of Boolean operators include the following:

• And

• Or

• Not

### The AND Operator

The And operator joins the value of x and y. The And operator takes two expressions that evaluate to a Boolean. The expression evaluates True only if both x and y are true. All other combinations result in a value of False.

Value of xValue of yx and y
TrueTrueTrue
TrueFalseFalse
FalseTrueFalse
FalseFalseFalse ### The OR Operator

The Or operator takes two expressions that evaluate to a Boolean. If either expression evaluates True, the operator returns True. If both expressions evaluate False, the operator returns False.

Value of xValue of yx and y
TrueTrueTrue
TrueFalseTrue
FalseTrueTrue
FalseFalseFalse ### The NOT Operator

The NOT operator reverses the True or False value of x.

Value of xNot x
TrueFalse
FalseTrue
