How a Computer Adds (and Multiplies) With Just a Few Switches | How Computers Do Math #2

Binary addition needs only four facts, and 1 + 1 = 10 is one of them. See how carries work in base 2, how AND, OR and XOR gates are built from switches, how five gates make a one-column adder, and how a chip multiplies by shifting and adding (13 × 5 = 13 × 4 + 13).
