Ngā Upane Otinga

Tangohia te 7 i te -20, ka -27.

$$sort(5\left(-27\right),109\left(-7\right)-9\left(-7\right))$$

Whakareatia te 5 ki te -27, ka -135.

$$sort(-135,109\left(-7\right)-9\left(-7\right))$$

Whakareatia te 109 ki te -7, ka -763.

$$sort(-135,-763-9\left(-7\right))$$

Whakareatia te 9 ki te -7, ka -63.

$$sort(-135,-763-\left(-63\right))$$

Ko te tauaro o -63 ko 63.

$$sort(-135,-763+63)$$

Tāpirihia te -763 ki te 63, ka -700.

$$sort(-135,-700)$$
