Tātaihia te \frac{1}{2} mā te pū o 3, kia riro ko \frac{1}{8}.

$$-2+\frac{\frac{1}{8}}{0.1^{-2}}$$

Tātaihia te 0.1 mā te pū o -2, kia riro ko 100.

$$-2+\frac{\frac{1}{8}}{100}$$

Tuhia te \frac{\frac{1}{8}}{100} hei hautanga kotahi.

$$-2+\frac{1}{8\times 100}$$

Whakareatia te 8 ki te 100, ka 800.

$$-2+\frac{1}{800}$$

Tāpirihia te -2 ki te \frac{1}{800}, ka -\frac{1599}{800}.

$$-\frac{1599}{800}$$
