In Boolean algebra, what does the '+' symbol typically represent?

In Boolean algebra, the '+' symbol typically represents the OR operation. This operation takes two binary inputs and returns a true (or '1') output if at least one of the inputs is true. The fundamental premise of the OR operation is that it yields true in cases where one or both of the operand states are true. For example, if you have two inputs, A and B, the expression A + B evaluates to true if either A is true, B is true, or both are true.

This aspect of the OR operation is crucial in various applications, including digital circuit design and logical expressions, where combining conditions is essential. Recognizing the significance of the '+' symbol as OR helps in constructing logical expressions and understanding their behavior in computational logic. In contrast, the other options represent different logical operations—AND, NAND, and XOR—each having distinct interpretations and functionality in Boolean expressions.
