Ngā Upane Otinga

Tātaihia te 80 mā te pū o 1, kia riro ko 80.

$$\frac{4}{80}-\frac{5^{4}}{-25}\left(-3\right)-769^{0}$$

Whakahekea te hautanga \frac{4}{80} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{1}{20}-\frac{5^{4}}{-25}\left(-3\right)-769^{0}$$

Tātaihia te 5 mā te pū o 4, kia riro ko 625.

$$\frac{1}{20}-\frac{625}{-25}\left(-3\right)-769^{0}$$

Whakawehea te 625 ki te -25, kia riro ko -25.

$$\frac{1}{20}-\left(-25\left(-3\right)\right)-769^{0}$$

Whakareatia te -25 ki te -3, ka 75.

$$\frac{1}{20}-75-769^{0}$$

Tangohia te 75 i te \frac{1}{20}, ka -\frac{1499}{20}.

$$-\frac{1499}{20}-769^{0}$$

Tātaihia te 769 mā te pū o 0, kia riro ko 1.

$$-\frac{1499}{20}-1$$

Tangohia te 1 i te -\frac{1499}{20}, ka -\frac{1519}{20}.

$$-\frac{1519}{20}$$

Tauwehe

$$-\frac{1519}{20} = -75\frac{19}{20} = -75.95$$
