Ngā Upane Otinga

Whakareatia te 23 ki te 4, ka 92.

$$49.7-\left(-\frac{92+3}{4}+18.7-25.25\right)$$

Tāpirihia te 92 ki te 3, ka 95.

$$49.7-\left(-\frac{95}{4}+18.7-25.25\right)$$

Me tahuri ki tau ā-ira 18.7 ki te hautau \frac{187}{10}.

$$49.7-\left(-\frac{95}{4}+\frac{187}{10}-25.25\right)$$

Ko te maha noa iti rawa atu o 4 me 10 ko 20. Me tahuri -\frac{95}{4} me \frac{187}{10} ki te hautau me te tautūnga 20.

$$49.7-\left(-\frac{475}{20}+\frac{374}{20}-25.25\right)$$

Tā te mea he rite te tauraro o -\frac{475}{20} me \frac{374}{20}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$49.7-\left(\frac{-475+374}{20}-25.25\right)$$

Tāpirihia te -475 ki te 374, ka -101.

$$49.7-\left(-\frac{101}{20}-25.25\right)$$

Me tahuri ki tau ā-ira 25.25 ki te hautau \frac{2525}{100}. Whakahekea te hautanga \frac{2525}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 25.

$$49.7-\left(-\frac{101}{20}-\frac{101}{4}\right)$$

Ko te maha noa iti rawa atu o 20 me 4 ko 20. Me tahuri -\frac{101}{20} me \frac{101}{4} ki te hautau me te tautūnga 20.

$$49.7-\left(-\frac{101}{20}-\frac{505}{20}\right)$$

Tā te mea he rite te tauraro o -\frac{101}{20} me \frac{505}{20}, me tango rāua mā te tango i ō raua taurunga.

$$49.7-\frac{-101-505}{20}$$

Tangohia te 505 i te -101, ka -606.

$$49.7-\frac{-606}{20}$$

Whakahekea te hautanga \frac{-606}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$49.7-\left(-\frac{303}{10}\right)$$

Ko te tauaro o -\frac{303}{10} ko \frac{303}{10}.

$$49.7+\frac{303}{10}$$

Me tahuri ki tau ā-ira 49.7 ki te hautau \frac{497}{10}.

$$\frac{497}{10}+\frac{303}{10}$$

Tā te mea he rite te tauraro o \frac{497}{10} me \frac{303}{10}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{497+303}{10}$$

Tāpirihia te 497 ki te 303, ka 800.

$$\frac{800}{10}$$

Whakawehea te 800 ki te 10, kia riro ko 80.
