Ngā Upane Otinga

Whakareatia te 2 ki te 2, ka 4.

$$\left(-\frac{4+1}{2}\right)\left(-0.5\right)^{3}\left(-2\right)^{2}\left(-8\right)$$

Tāpirihia te 4 ki te 1, ka 5.

$$-\frac{5}{2}\left(-0.5\right)^{3}\left(-2\right)^{2}\left(-8\right)$$

Tātaihia te -0.5 mā te pū o 3, kia riro ko -0.125.

$$-\frac{5}{2}\left(-0.125\right)\left(-2\right)^{2}\left(-8\right)$$

Me tahuri ki tau ā-ira -0.125 ki te hautau -\frac{125}{1000}. Whakahekea te hautanga -\frac{125}{1000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 125.

$$-\frac{5}{2}\left(-\frac{1}{8}\right)\left(-2\right)^{2}\left(-8\right)$$

Me whakarea te -\frac{5}{2} ki te -\frac{1}{8} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{-5\left(-1\right)}{2\times 8}\left(-2\right)^{2}\left(-8\right)$$

Mahia ngā whakarea i roto i te hautanga \frac{-5\left(-1\right)}{2\times 8}.

$$\frac{5}{16}\left(-2\right)^{2}\left(-8\right)$$

Tātaihia te -2 mā te pū o 2, kia riro ko 4.

$$\frac{5}{16}\times 4\left(-8\right)$$

Tuhia te \frac{5}{16}\times 4 hei hautanga kotahi.

$$\frac{5\times 4}{16}\left(-8\right)$$

Whakareatia te 5 ki te 4, ka 20.

$$\frac{20}{16}\left(-8\right)$$

Whakahekea te hautanga \frac{20}{16} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{5}{4}\left(-8\right)$$

Tuhia te \frac{5}{4}\left(-8\right) hei hautanga kotahi.

$$\frac{5\left(-8\right)}{4}$$

Whakareatia te 5 ki te -8, ka -40.

$$\frac{-40}{4}$$

Whakawehea te -40 ki te 4, kia riro ko -10.
