The AND operator returns true only when both inputs are true. Written as && in most languages, or and in Python. Mathematically:
is if and only if both and are .
If either input is false, the result is false. Think of AND as a gate: both conditions must pass for the gate to open. One failure blocks everything.
Example: if (age >= 18 && hasLicense) checks two things. If age is 20 but hasLicense is false, the whole expression is false.
