Ngā Upane Otinga

Whakareatia te 1 ki te 4, ka 4.

$$\frac{4+3}{4}-6.25-\left(-\frac{27}{8}\right)-1.75$$

Tāpirihia te 4 ki te 3, ka 7.

$$\frac{7}{4}-6.25-\left(-\frac{27}{8}\right)-1.75$$

Me tahuri ki tau ā-ira 6.25 ki te hautau \frac{625}{100}. Whakahekea te hautanga \frac{625}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$\frac{7}{4}-\frac{25}{4}-\left(-\frac{27}{8}\right)-1.75$$

Tā te mea he rite te tauraro o \frac{7}{4} me \frac{25}{4}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{7-25}{4}-\left(-\frac{27}{8}\right)-1.75$$

Tangohia te 25 i te 7, ka -18.

$$\frac{-18}{4}-\left(-\frac{27}{8}\right)-1.75$$

Whakahekea te hautanga \frac{-18}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-\frac{9}{2}-\left(-\frac{27}{8}\right)-1.75$$

Ko te tauaro o -\frac{27}{8} ko \frac{27}{8}.

$$-\frac{9}{2}+\frac{27}{8}-1.75$$

Ko te maha noa iti rawa atu o 2 me 8 ko 8. Me tahuri -\frac{9}{2} me \frac{27}{8} ki te hautau me te tautūnga 8.

$$-\frac{36}{8}+\frac{27}{8}-1.75$$

Tā te mea he rite te tauraro o -\frac{36}{8} me \frac{27}{8}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-36+27}{8}-1.75$$

Tāpirihia te -36 ki te 27, ka -9.

$$-\frac{9}{8}-1.75$$

Me tahuri ki tau ā-ira 1.75 ki te hautau \frac{175}{100}. Whakahekea te hautanga \frac{175}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$-\frac{9}{8}-\frac{7}{4}$$

Ko te maha noa iti rawa atu o 8 me 4 ko 8. Me tahuri -\frac{9}{8} me \frac{7}{4} ki te hautau me te tautūnga 8.

$$-\frac{9}{8}-\frac{14}{8}$$

Tā te mea he rite te tauraro o -\frac{9}{8} me \frac{14}{8}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-9-14}{8}$$

Tangohia te 14 i te -9, ka -23.

$$-\frac{23}{8}$$
