AND, OR and XOR Logic Gates with Two Inputs
Two logic inputs, A and B, drive an AND, an OR and an XOR gate. Click an input to switch it between 0 and 1 and watch the three outputs follow the truth…

Click input A or input B to switch it between 0 and 1. Each input feeds all three gates, and each gate drives its own output: A AND B is 1 only when both inputs are 1, A OR B is 1 when either input is 1, and A XOR B is 1 when exactly one input is 1.
Try all four combinations of A and B and write down the three outputs each time. The table you get is the truth table of the three gates. The XOR and AND outputs together are a half adder: XOR gives the sum bit and AND gives the carry.
