Ngā Upane Otinga

Ko te maha noa iti rawa atu o 3 me 4 ko 12. Me tahuri -\frac{2}{3} me \frac{1}{4} ki te hautau me te tautūnga 12.

$$-\frac{8}{12}+\frac{3}{12}-\left(-\frac{3}{4}\right)$$

Tā te mea he rite te tauraro o -\frac{8}{12} me \frac{3}{12}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-8+3}{12}-\left(-\frac{3}{4}\right)$$

Tāpirihia te -8 ki te 3, ka -5.

$$-\frac{5}{12}-\left(-\frac{3}{4}\right)$$

Ko te tauaro o -\frac{3}{4} ko \frac{3}{4}.

$$-\frac{5}{12}+\frac{3}{4}$$

Ko te maha noa iti rawa atu o 12 me 4 ko 12. Me tahuri -\frac{5}{12} me \frac{3}{4} ki te hautau me te tautūnga 12.

$$-\frac{5}{12}+\frac{9}{12}$$

Tā te mea he rite te tauraro o -\frac{5}{12} me \frac{9}{12}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-5+9}{12}$$

Tāpirihia te -5 ki te 9, ka 4.

$$\frac{4}{12}$$

Whakahekea te hautanga \frac{4}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
