Ngā Upane Otinga

Tātaihia te 84 mā te pū o 3, kia riro ko 592704.

$$\frac{\frac{592704+66^{3}}{150}-84\times 66}{12^{2}-6^{2}}$$

Tātaihia te 66 mā te pū o 3, kia riro ko 287496.

$$\frac{\frac{592704+287496}{150}-84\times 66}{12^{2}-6^{2}}$$

Tāpirihia te 592704 ki te 287496, ka 880200.

$$\frac{\frac{880200}{150}-84\times 66}{12^{2}-6^{2}}$$

Whakawehea te 880200 ki te 150, kia riro ko 5868.

$$\frac{5868-84\times 66}{12^{2}-6^{2}}$$

Whakareatia te 84 ki te 66, ka 5544.

$$\frac{5868-5544}{12^{2}-6^{2}}$$

Tangohia te 5544 i te 5868, ka 324.

$$\frac{324}{12^{2}-6^{2}}$$

Tātaihia te 12 mā te pū o 2, kia riro ko 144.

$$\frac{324}{144-6^{2}}$$

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

$$\frac{324}{144-36}$$

Tangohia te 36 i te 144, ka 108.

$$\frac{324}{108}$$

Whakawehea te 324 ki te 108, kia riro ko 3.
