Ngā Upane Otinga

Ko te maha noa iti rawa atu o 3 me 6 ko 6. Me tahuri -\frac{2}{3} me \frac{1}{6} ki te hautau me te tautūnga 6.

$$-\frac{4}{6}-\frac{1}{6}-\left(-\frac{1}{4}\right)-\frac{1}{2}$$

Tā te mea he rite te tauraro o -\frac{4}{6} me \frac{1}{6}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-4-1}{6}-\left(-\frac{1}{4}\right)-\frac{1}{2}$$

Tangohia te 1 i te -4, ka -5.

$$-\frac{5}{6}-\left(-\frac{1}{4}\right)-\frac{1}{2}$$

Ko te tauaro o -\frac{1}{4} ko \frac{1}{4}.

$$-\frac{5}{6}+\frac{1}{4}-\frac{1}{2}$$

Ko te maha noa iti rawa atu o 6 me 4 ko 12. Me tahuri -\frac{5}{6} me \frac{1}{4} ki te hautau me te tautūnga 12.

$$-\frac{10}{12}+\frac{3}{12}-\frac{1}{2}$$

Tā te mea he rite te tauraro o -\frac{10}{12} me \frac{3}{12}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-10+3}{12}-\frac{1}{2}$$

Tāpirihia te -10 ki te 3, ka -7.

$$-\frac{7}{12}-\frac{1}{2}$$

Ko te maha noa iti rawa atu o 12 me 2 ko 12. Me tahuri -\frac{7}{12} me \frac{1}{2} ki te hautau me te tautūnga 12.

$$-\frac{7}{12}-\frac{6}{12}$$

Tā te mea he rite te tauraro o -\frac{7}{12} me \frac{6}{12}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-7-6}{12}$$

Tangohia te 6 i te -7, ka -13.

$$-\frac{13}{12}$$

Tauwehe

$$-\frac{13}{12} = -1\frac{1}{12} = -1.0833333333333333$$
