Ngā Upane Otinga

Whakareatia te 1 ki te 3, ka 3.

$$-2.7+\frac{3+1}{3}+1.6-\frac{4\times 6+5}{6}$$

Tāpirihia te 3 ki te 1, ka 4.

$$-2.7+\frac{4}{3}+1.6-\frac{4\times 6+5}{6}$$

Me tahuri ki tau ā-ira -2.7 ki te hautau -\frac{27}{10}.

Ko te maha noa iti rawa atu o 10 me 3 ko 30. Me tahuri -\frac{27}{10} me \frac{4}{3} ki te hautau me te tautūnga 30.

$$-\frac{81}{30}+\frac{40}{30}+1.6-\frac{4\times 6+5}{6}$$

Tā te mea he rite te tauraro o -\frac{81}{30} me \frac{40}{30}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-81+40}{30}+1.6-\frac{4\times 6+5}{6}$$

Tāpirihia te -81 ki te 40, ka -41.

$$-\frac{41}{30}+1.6-\frac{4\times 6+5}{6}$$

Me tahuri ki tau ā-ira 1.6 ki te hautau \frac{16}{10}. Whakahekea te hautanga \frac{16}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-\frac{41}{30}+\frac{8}{5}-\frac{4\times 6+5}{6}$$

Ko te maha noa iti rawa atu o 30 me 5 ko 30. Me tahuri -\frac{41}{30} me \frac{8}{5} ki te hautau me te tautūnga 30.

$$-\frac{41}{30}+\frac{48}{30}-\frac{4\times 6+5}{6}$$

Tā te mea he rite te tauraro o -\frac{41}{30} me \frac{48}{30}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-41+48}{30}-\frac{4\times 6+5}{6}$$

Tāpirihia te -41 ki te 48, ka 7.

$$\frac{7}{30}-\frac{4\times 6+5}{6}$$

Whakareatia te 4 ki te 6, ka 24.

$$\frac{7}{30}-\frac{24+5}{6}$$

Tāpirihia te 24 ki te 5, ka 29.

$$\frac{7}{30}-\frac{29}{6}$$

Ko te maha noa iti rawa atu o 30 me 6 ko 30. Me tahuri \frac{7}{30} me \frac{29}{6} ki te hautau me te tautūnga 30.

$$\frac{7}{30}-\frac{145}{30}$$

Tā te mea he rite te tauraro o \frac{7}{30} me \frac{145}{30}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{7-145}{30}$$

Tangohia te 145 i te 7, ka -138.

$$\frac{-138}{30}$$

Whakahekea te hautanga \frac{-138}{30} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.
