Ngā Upane Otinga

Tāpirihia te 10 ki te 2, ka 12.

$$\frac{12\left(2\times 10-3\right)-2\times 10^{2}+6}{10-5}$$

Whakareatia te 2 ki te 10, ka 20.

$$\frac{12\left(20-3\right)-2\times 10^{2}+6}{10-5}$$

Tangohia te 3 i te 20, ka 17.

$$\frac{12\times 17-2\times 10^{2}+6}{10-5}$$

Whakareatia te 12 ki te 17, ka 204.

$$\frac{204-2\times 10^{2}+6}{10-5}$$

Tātaihia te 10 mā te pū o 2, kia riro ko 100.

$$\frac{204-2\times 100+6}{10-5}$$

Whakareatia te 2 ki te 100, ka 200.

$$\frac{204-200+6}{10-5}$$

Tangohia te 200 i te 204, ka 4.

$$\frac{4+6}{10-5}$$

Tāpirihia te 4 ki te 6, ka 10.

$$\frac{10}{10-5}$$

Tangohia te 5 i te 10, ka 5.

$$\frac{10}{5}$$

Whakawehea te 10 ki te 5, kia riro ko 2.
