Ngā Upane Otinga

Tāpirihia te 5.1 ki te 8.4, ka 13.5.

$$13.5-\left(-5.1\right)-10.2-8.4-9.8-\left(-15\right)$$

Ko te tauaro o -5.1 ko 5.1.

$$13.5+5.1-10.2-8.4-9.8-\left(-15\right)$$

Tāpirihia te 13.5 ki te 5.1, ka 18.6.

$$18.6-10.2-8.4-9.8-\left(-15\right)$$

$$8.4-8.4-9.8-\left(-15\right)$$

Tangohia te 8.4 i te 8.4, ka 0.

$$-9.8-\left(-15\right)$$

Ko te tauaro o -15 ko 15.

$$-9.8+15$$
