Ngā Upane Otinga

Tāpirihia te 6 ki te 2, ka 8.

$$\frac{8\left(7-4\right)}{14-2}+\frac{\left(12-8\right)\left(7+3\right)}{10-2}$$

Tangohia te 4 i te 7, ka 3.

$$\frac{8\times 3}{14-2}+\frac{\left(12-8\right)\left(7+3\right)}{10-2}$$

Whakareatia te 8 ki te 3, ka 24.

$$\frac{24}{14-2}+\frac{\left(12-8\right)\left(7+3\right)}{10-2}$$

Tangohia te 2 i te 14, ka 12.

$$\frac{24}{12}+\frac{\left(12-8\right)\left(7+3\right)}{10-2}$$

Whakawehea te 24 ki te 12, kia riro ko 2.

$$2+\frac{\left(12-8\right)\left(7+3\right)}{10-2}$$

Tangohia te 8 i te 12, ka 4.

$$2+\frac{4\left(7+3\right)}{10-2}$$

Tāpirihia te 7 ki te 3, ka 10.

$$2+\frac{4\times 10}{10-2}$$

Whakareatia te 4 ki te 10, ka 40.

$$2+\frac{40}{10-2}$$

Tangohia te 2 i te 10, ka 8.

$$2+\frac{40}{8}$$

Whakawehea te 40 ki te 8, kia riro ko 5.

$$2+5$$

Tāpirihia te 2 ki te 5, ka 7.
