Ngā Upane Otinga

Whakarohaina te \frac{6}{-1.8} mā te whakarea i te taurunga me te tauraro ki te 10.

$$\frac{60}{-18}-\frac{3}{2\left(-1.8\right)}$$

Whakahekea te hautanga \frac{60}{-18} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.

$$-\frac{10}{3}-\frac{3}{2\left(-1.8\right)}$$

Whakareatia te 2 ki te -1.8, ka -3.6.

$$-\frac{10}{3}-\frac{3}{-3.6}$$

Whakarohaina te \frac{3}{-3.6} mā te whakarea i te taurunga me te tauraro ki te 10.

$$-\frac{10}{3}-\frac{30}{-36}$$

Whakahekea te hautanga \frac{30}{-36} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.

$$-\frac{10}{3}-\left(-\frac{5}{6}\right)$$

Ko te tauaro o -\frac{5}{6} ko \frac{5}{6}.

$$-\frac{10}{3}+\frac{5}{6}$$

Ko te maha noa iti rawa atu o 3 me 6 ko 6. Me tahuri -\frac{10}{3} me \frac{5}{6} ki te hautau me te tautūnga 6.

$$-\frac{20}{6}+\frac{5}{6}$$

Tā te mea he rite te tauraro o -\frac{20}{6} me \frac{5}{6}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-20+5}{6}$$

Tāpirihia te -20 ki te 5, ka -15.

$$\frac{-15}{6}$$

Whakahekea te hautanga \frac{-15}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
