# Logical AND symbol

The logical AND symbol is a Boolean operator that returns TRUE if both of the operands are TRUE, and FALSE if any of the operands are FALSE.

The logical AND operator is typically used with Boolean variables, and can be thought of as a way to "short-circuit" the evaluation of a Boolean expression. If the first operand is FALSE, the second operand is not even evaluated, since the entire expression must be FALSE no matter what the value of the second operand is. What does ≡ mean in logic? In logic, ≡ means "is equivalent to". What does ↔ mean in math? The symbol ↔ is used in mathematical logic to denote the equivalence relation. In other words, ↔ means "if and only if". What does → mean in logic? The arrow symbol → in logic denotes a logical implication. In other words, the statement "A → B" means that if A is true, then B must also be true. What does ∧ mean in logic? In logic, ∧ is the symbol for conjunction. Conjunction is a binary logical operator that produces a true value only if both of its operands are true. What does ⊕ mean? The ⊕ symbol is a mathematical operator known as exclusive or, or XOR. In programming, it is a boolean operation that returns true if and only if exactly one of its operands is true.
