Tātaihia te -0.7 mā te pū o 2, kia riro ko 0.49.

$$0.49\times 10^{2}+\left(-0.2\times 10\right)^{3}$$

Tātaihia te 10 mā te pū o 2, kia riro ko 100.

$$0.49\times 100+\left(-0.2\times 10\right)^{3}$$

Whakareatia te 0.49 ki te 100, ka 49.

$$49+\left(-0.2\times 10\right)^{3}$$

Whakareatia te -0.2 ki te 10, ka -2.

$$49+\left(-2\right)^{3}$$

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

$$49-8$$

Tangohia te 8 i te 49, ka 41.
