Ngā Upane Otinga

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

$$2-6\left(\frac{3}{6}-\frac{4}{6}+\frac{5}{6}\right)$$

Tā te mea he rite te tauraro o \frac{3}{6} me \frac{4}{6}, me tango rāua mā te tango i ō raua taurunga.

$$2-6\left(\frac{3-4}{6}+\frac{5}{6}\right)$$

Tangohia te 4 i te 3, ka -1.

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

Tā te mea he rite te tauraro o -\frac{1}{6} me \frac{5}{6}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

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

Tāpirihia te -1 ki te 5, ka 4.

$$2-6\times \frac{4}{6}$$

Whakahekea te hautanga \frac{4}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$2-6\times \frac{2}{3}$$

Tuhia te 6\times \frac{2}{3} hei hautanga kotahi.

$$2-\frac{6\times 2}{3}$$

Whakareatia te 6 ki te 2, ka 12.

$$2-\frac{12}{3}$$

Whakawehea te 12 ki te 3, kia riro ko 4.

$$2-4$$

Tangohia te 4 i te 2, ka -2.
