Disjunction is a logical operation that connects two statements, typically represented by the word "or." In formal logic, it is denoted by the symbol ∨. A disjunction is true if at least one of the statements it connects is true. For example, in the statement "It is raining or it is sunny," the disjunction is true if either condition is met. In mathematics and computer science, disjunction is often used in Boolean algebra and programming. It helps in decision-making processes, where multiple conditions can lead to a true outcome. Understanding disjunction is essential for constructing logical arguments and algorithms in various fields, including mathematics and computer science.
