Tātaihia te 3.3 mā te pū o 3, kia riro ko 35.937.

$$\frac{1}{2}\times 35.937-\frac{5}{2}\times 3.3^{2}$$

Me tahuri ki tau ā-ira 35.937 ki te hautau \frac{35937}{1000}.

$$\frac{1}{2}\times \frac{35937}{1000}-\frac{5}{2}\times 3.3^{2}$$

Me whakarea te \frac{1}{2} ki te \frac{35937}{1000} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{1\times 35937}{2\times 1000}-\frac{5}{2}\times 3.3^{2}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 35937}{2\times 1000}.

$$\frac{35937}{2000}-\frac{5}{2}\times 3.3^{2}$$

Tātaihia te 3.3 mā te pū o 2, kia riro ko 10.89.

$$\frac{35937}{2000}-\frac{5}{2}\times 10.89$$

Me tahuri ki tau ā-ira 10.89 ki te hautau \frac{1089}{100}.

$$\frac{35937}{2000}-\frac{5}{2}\times \frac{1089}{100}$$

Me whakarea te \frac{5}{2} ki te \frac{1089}{100} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{35937}{2000}-\frac{5\times 1089}{2\times 100}$$

Mahia ngā whakarea i roto i te hautanga \frac{5\times 1089}{2\times 100}.

$$\frac{35937}{2000}-\frac{5445}{200}$$

Whakahekea te hautanga \frac{5445}{200} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{35937}{2000}-\frac{1089}{40}$$

Ko te maha noa iti rawa atu o 2000 me 40 ko 2000. Me tahuri \frac{35937}{2000} me \frac{1089}{40} ki te hautau me te tautūnga 2000.

$$\frac{35937}{2000}-\frac{54450}{2000}$$

Tā te mea he rite te tauraro o \frac{35937}{2000} me \frac{54450}{2000}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{35937-54450}{2000}$$

Tangohia te 54450 i te 35937, ka -18513.
