A ripple-carry adder chains full-adders: each bit adds A, B, and the carry from the bit below, passing its own carry upward. That carry ripple is why simple adders slow down as they get wider. Educational tool.

▶ Run in Python

Data Inspector

A + B (decimal)83 + 58 = 141

Carry out0

Governing equation

S C_{o u t} = A \oplus B \oplus C_{in} = A B + C_{in} (A \oplus B) = 0

Reading this result: A carry is generated in 4 of the 8 columns, and each one must wait for the column below it — that wait is why wide ripple adders slow down.
