Ngā Upane Otinga

Whakareatia te 5 ki te 2, ka 10.

$$4-10+3\left(8-\left(6-9\right)\times 2\right)$$

Tangohia te 10 i te 4, ka -6.

$$-6+3\left(8-\left(6-9\right)\times 2\right)$$

Tangohia te 9 i te 6, ka -3.

$$-6+3\left(8-\left(-3\times 2\right)\right)$$

Whakareatia te -3 ki te 2, ka -6.

$$-6+3\left(8-\left(-6\right)\right)$$

Ko te tauaro o -6 ko 6.

$$-6+3\left(8+6\right)$$

Tāpirihia te 8 ki te 6, ka 14.

$$-6+3\times 14$$

Whakareatia te 3 ki te 14, ka 42.

$$-6+42$$

Tāpirihia te -6 ki te 42, ka 36.

$$36$$
