Ko te maha noa iti rawa atu o 3 me 6 ko 6. Me tahuri \frac{2}{3} me \frac{19}{6} ki te hautau me te tautūnga 6.

$$\frac{4}{6}-\frac{19}{6}+0.5$$

Tā te mea he rite te tauraro o \frac{4}{6} me \frac{19}{6}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{4-19}{6}+0.5$$

Tangohia te 19 i te 4, ka -15.

$$\frac{-15}{6}+0.5$$

Whakahekea te hautanga \frac{-15}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$-\frac{5}{2}+0.5$$

Me tahuri ki tau ā-ira 0.5 ki te hautau \frac{5}{10}. Whakahekea te hautanga \frac{5}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$-\frac{5}{2}+\frac{1}{2}$$

Tā te mea he rite te tauraro o -\frac{5}{2} me \frac{1}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-5+1}{2}$$

Tāpirihia te -5 ki te 1, ka -4.

$$\frac{-4}{2}$$

Whakawehea te -4 ki te 2, kia riro ko -2.
