AND gate

INPUT OUTPUT
A B A AND B
0 0 0
0 1 0
1 0 0
1 1 1

The AND gate is a logic gate that outputs 1 (true) only when both of its inputs are 1 (true). Since 0 is false, AND outputs the product (result of multiplication) of its inputs. That means that if either or both of its inputs are 0, the output will be 0 (zero multiplied by any real number is zero).
