Ngā Upane Otinga

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te -8 me te -4 kia riro ai te -12.

$$9\times 20\times 10^{-12}\times 0\times 2$$

Whakareatia te 9 ki te 20, ka 180.

$$180\times 10^{-12}\times 0\times 2$$

Tātaihia te 10 mā te pū o -12, kia riro ko \frac{1}{1000000000000}.

$$180\times \frac{1}{1000000000000}\times 0\times 2$$

Whakareatia te 180 ki te \frac{1}{1000000000000}, ka \frac{9}{50000000000}.

$$\frac{9}{50000000000}\times 0\times 2$$

Whakareatia te \frac{9}{50000000000} ki te 0, ka 0.

$$0\times 2$$

Whakareatia te 0 ki te 2, ka 0.

$$0$$
