Tātaihia te 2 mā te pū o 3, kia riro ko 8.

$$1\times 8+1\times 2^{2}+0\times 2^{1}+1\times 2^{0}$$

Whakareatia te 1 ki te 8, ka 8.

$$8+1\times 2^{2}+0\times 2^{1}+1\times 2^{0}$$

Tātaihia te 2 mā te pū o 2, kia riro ko 4.

$$8+1\times 4+0\times 2^{1}+1\times 2^{0}$$

Whakareatia te 1 ki te 4, ka 4.

$$8+4+0\times 2^{1}+1\times 2^{0}$$

Tāpirihia te 8 ki te 4, ka 12.
