Ngā Upane Otinga

Whakareatia te 8 ki te 4, ka 32.

$$-0.6+\frac{32+1}{4}\left(-0.2\right)$$

Tāpirihia te 32 ki te 1, ka 33.

$$-0.6+\frac{33}{4}\left(-0.2\right)$$

Me tahuri ki tau ā-ira -0.2 ki te hautau -\frac{2}{10}. Whakahekea te hautanga -\frac{2}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-0.6+\frac{33}{4}\left(-\frac{1}{5}\right)$$

Me whakarea te \frac{33}{4} ki te -\frac{1}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$-0.6+\frac{33\left(-1\right)}{4\times 5}$$

Mahia ngā whakarea i roto i te hautanga \frac{33\left(-1\right)}{4\times 5}.

$$-0.6+\frac{-33}{20}$$

Ka taea te hautanga \frac{-33}{20} te tuhi anō ko -\frac{33}{20} mā te tango i te tohu tōraro.

$$-0.6-\frac{33}{20}$$

Me tahuri ki tau ā-ira -0.6 ki te hautau -\frac{6}{10}. Whakahekea te hautanga -\frac{6}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$-\frac{3}{5}-\frac{33}{20}$$

Ko te maha noa iti rawa atu o 5 me 20 ko 20. Me tahuri -\frac{3}{5} me \frac{33}{20} ki te hautau me te tautūnga 20.

$$-\frac{12}{20}-\frac{33}{20}$$

Tā te mea he rite te tauraro o -\frac{12}{20} me \frac{33}{20}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{-12-33}{20}$$

Tangohia te 33 i te -12, ka -45.

$$\frac{-45}{20}$$

Whakahekea te hautanga \frac{-45}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

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