In Boolean algebra, the notation XY means which operation?

Explanation:
XY denotes the AND operation: both X and Y must be true for the result to be true. In Boolean terms, it’s like multiplication—1 AND 1 gives 1, but any other combination (X or Y being 0) yields 0. This is why XY is read as “X and Y.” It isn’t a negation (NOT X), it isn’t OR (X OR Y, which is true if either input is true), and it isn’t XOR (which is true when exactly one input is true).
