Ngā Upane Otinga

Whakareatia te \frac{1}{2} ki te 30, ka \frac{30}{2}.

$$\frac{30}{2}\left(253^{2}-1^{2}\right)$$

Whakawehea te 30 ki te 2, kia riro ko 15.

$$15\left(253^{2}-1^{2}\right)$$

Tātaihia te 253 mā te pū o 2, kia riro ko 64009.

$$15\left(64009-1^{2}\right)$$

Tātaihia te 1 mā te pū o 2, kia riro ko 1.

$$15\left(64009-1\right)$$

Tangohia te 1 i te 64009, ka 64008.

$$15\times 64008$$

Whakareatia te 15 ki te 64008, ka 960120.

$$960120$$
