• To add in binary use the same technique (algorithm), but restrict yourself to 0 and 1 … everything else works the same way

1 1 0 0 1 12 51

1 1 1 0 1 02 58
1 1 0 1 1 0 12 109

• Binary is pretty tedious for humans because there are so many digits … circuitry benefits however because it uses the two states (on/off) efficiently
