Ngā Upane Otinga

Whakareatia te 0 ki te 3, ka 0.

$$0+\frac{4}{5}\left(-\frac{2\times 2+1}{2}\right)$$

Whakareatia te 2 ki te 2, ka 4.

$$0+\frac{4}{5}\left(-\frac{4+1}{2}\right)$$

Tāpirihia te 4 ki te 1, ka 5.

$$0+\frac{4}{5}\left(-\frac{5}{2}\right)$$

Me whakarea te \frac{4}{5} ki te -\frac{5}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$0+\frac{4\left(-5\right)}{5\times 2}$$

Mahia ngā whakarea i roto i te hautanga \frac{4\left(-5\right)}{5\times 2}.

$$0+\frac{-20}{10}$$

Whakawehea te -20 ki te 10, kia riro ko -2.

$$0-2$$

Tangohia te 2 i te 0, ka -2.
