Inclusive Disjunction Operator (OR)

The inclusive disjunction operator, often denoted as “OR”, is a logical operator used in mathematics and logic to connect two statements or conditions

The inclusive disjunction operator, often denoted as “OR”, is a logical operator used in mathematics and logic to connect two statements or conditions. In mathematical terms, the OR operator returns true if at least one of the conditions is true, and false only when both conditions are false.

To illustrate this, let’s consider two statements, A and B. The OR operator is represented as A OR B. The truth table below summarizes the possible combinations:

A | B | A OR B
———————–
true | true | true
true | false | true
false| true | true
false| false | false

As seen in the truth table, the OR operator evaluates to true if either A or B (or both) is true. It is only false when both A and B are false.

In mathematics, the OR operator is used to combine conditions and statements in various contexts. It is commonly used in algebraic equations, inequalities, and logical propositions. For example, when solving an inequality like x > 5 OR x < 2, the OR operator indicates that x can either be greater than 5 or less than 2, or potentially both. When working with mathematical proofs or logic, the inclusive disjunction operator helps establish alternative possibilities and allows for more flexible reasoning.
