Tāpirihia te 0.0027 ki te 0.014, ka 0.0167.

$$0.0167+\frac{0.4\left(0.4-1\right)\times 0.0035}{2}$$

Tangohia te 1 i te 0.4, ka -0.6.

$$0.0167+\frac{0.4\left(-0.6\right)\times 0.0035}{2}$$

Whakareatia te 0.4 ki te -0.6, ka -0.24.

$$0.0167+\frac{-0.24\times 0.0035}{2}$$

Whakareatia te -0.24 ki te 0.0035, ka -0.00084.

$$0.0167+\frac{-0.00084}{2}$$

Whakarohaina te \frac{-0.00084}{2} mā te whakarea i te taurunga me te tauraro ki te 100000.

$$0.0167+\frac{-84}{200000}$$

Whakahekea te hautanga \frac{-84}{200000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$0.0167-\frac{21}{50000}$$

Me tahuri ki tau ā-ira 0.0167 ki te hautau \frac{167}{10000}.

$$\frac{167}{10000}-\frac{21}{50000}$$

Ko te maha noa iti rawa atu o 10000 me 50000 ko 50000. Me tahuri \frac{167}{10000} me \frac{21}{50000} ki te hautau me te tautūnga 50000.

$$\frac{835}{50000}-\frac{21}{50000}$$

Tā te mea he rite te tauraro o \frac{835}{50000} me \frac{21}{50000}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{835-21}{50000}$$

Tangohia te 21 i te 835, ka 814.

$$\frac{814}{50000}$$

Whakahekea te hautanga \frac{814}{50000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
