How a calculator adds numbers

Référence de la vidéo 12544025
Animation showing how a combination of logic gates perform addition of numbers inside an electronic calculator. The blue digits show the base ten numbers represented by the binary numbers in the red digits. The white boxes each contain a combination of logic gates called a full adder, which has two controllable inputs (above) and one input from the adder to its right in the row. Each adder sums its inputs, and carries a significant figure to its left if the result is more than one. This adds the binary numbers of the two rows of inputs. Inside an electronic calculator, this array of adders is formed on an integrated circuit, which is itself embedded on a printed circuit board, which connects the integrated circuit to a battery, display screen and input keys. See clip K007/6877 for the internal logic gate structure of the full adder.
