Whakareatia te 40 ki te 30, ka 1200. Whakareatia te 35 ki te 19366, ka 677810.

$$1200\times \frac{1}{2}+677810\times \frac{1}{2}$$

Whakareatia te 1200 ki te \frac{1}{2}, ka \frac{1200}{2}.

$$\frac{1200}{2}+677810\times \frac{1}{2}$$

Whakawehea te 1200 ki te 2, kia riro ko 600.

$$600+677810\times \frac{1}{2}$$

Whakareatia te 677810 ki te \frac{1}{2}, ka \frac{677810}{2}.

$$600+\frac{677810}{2}$$

Whakawehea te 677810 ki te 2, kia riro ko 338905.

$$600+338905$$

Tāpirihia te 600 ki te 338905, ka 339505.

$$339505$$
