Ngā Upane Otinga

Tangohia te 1 i te -8, ka -9.

$$-9\left(3-\frac{-7.2}{-2.5+3}\right)$$

Tāpirihia te -2.5 ki te 3, ka 0.5.

$$-9\left(3-\frac{-7.2}{0.5}\right)$$

Whakarohaina te \frac{-7.2}{0.5} mā te whakarea i te taurunga me te tauraro ki te 10.

$$-9\left(3-\frac{-72}{5}\right)$$

Ka taea te hautanga \frac{-72}{5} te tuhi anō ko -\frac{72}{5} mā te tango i te tohu tōraro.

$$-9\left(3-\left(-\frac{72}{5}\right)\right)$$

Ko te tauaro o -\frac{72}{5} ko \frac{72}{5}.

$$-9\left(3+\frac{72}{5}\right)$$

Me tahuri te 3 ki te hautau \frac{15}{5}.

$$-9\left(\frac{15}{5}+\frac{72}{5}\right)$$

Tā te mea he rite te tauraro o \frac{15}{5} me \frac{72}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$-9\times \frac{15+72}{5}$$

Tāpirihia te 15 ki te 72, ka 87.

$$-9\times \frac{87}{5}$$

Tuhia te -9\times \frac{87}{5} hei hautanga kotahi.

$$\frac{-9\times 87}{5}$$

Whakareatia te -9 ki te 87, ka -783.

$$\frac{-783}{5}$$

Ka taea te hautanga \frac{-783}{5} te tuhi anō ko -\frac{783}{5} mā te tango i te tohu tōraro.

$$-\frac{783}{5}$$
