Dalam contoh ini, dua angka sedang ditambah: 011012 (1310) dan 101112 (2310). The top row shows the carry bits used. Starting in the rightmost column, 1 + 1 = 102. The 1 is carried to the left, dan the 0 is written at the bottom of the rightmost column. The second column from the right is added: 1 + 0 + 1 = 102 again; the 1 is carried, dan 0 is written at the bottom. The third column: 1 + 1 + 1 = 112. This time, a 1 is carried, dan a 1 is written in the bottom row. Proceeding like this gives the final answer 1001002 (36 decimal).
