Ngā Upane Otinga

Tangohia te 6 i te 3, ka -3.

$$5\left(-4\left(-3\right)-2\left(7-5\right)+2\right)-4$$

Whakareatia te -4 ki te -3, ka 12.

$$5\left(12-2\left(7-5\right)+2\right)-4$$

Tangohia te 5 i te 7, ka 2.

$$5\left(12-2\times 2+2\right)-4$$

Whakareatia te 2 ki te 2, ka 4.

$$5\left(12-4+2\right)-4$$

Tangohia te 4 i te 12, ka 8.

$$5\left(8+2\right)-4$$

Tāpirihia te 8 ki te 2, ka 10.

$$5\times 10-4$$

Whakareatia te 5 ki te 10, ka 50.

$$50-4$$

Tangohia te 4 i te 50, ka 46.
