Aromātai

$$30$$

Ngā Upane Otinga

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

$$100-80+\frac{6^{2}\times 3}{6}-8$$

Tangohia te 80 i te 100, ka 20.

$$20+\frac{6^{2}\times 3}{6}-8$$

Tātaihia te 6 mā te pū o 2, kia riro ko 36.

$$20+\frac{36\times 3}{6}-8$$

Whakareatia te 36 ki te 3, ka 108.

$$20+\frac{108}{6}-8$$

Whakawehea te 108 ki te 6, kia riro ko 18.

$$20+18-8$$

Tāpirihia te 20 ki te 18, ka 38.

$$38-8$$

Tangohia te 8 i te 38, ka 30.
