Me whakarea te -\frac{2}{3} ki te \frac{3}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{-2\times 3}{3\times 5}+\frac{5}{2}-\frac{3}{5}\times \frac{1}{6}$$

Me whakakore tahi te 3 i te taurunga me te tauraro.

$$\frac{-2}{5}+\frac{5}{2}-\frac{3}{5}\times \frac{1}{6}$$

Ka taea te hautanga \frac{-2}{5} te tuhi anō ko -\frac{2}{5} mā te tango i te tohu tōraro.

$$-\frac{2}{5}+\frac{5}{2}-\frac{3}{5}\times \frac{1}{6}$$

Ko te maha noa iti rawa atu o 5 me 2 ko 10. Me tahuri -\frac{2}{5} me \frac{5}{2} ki te hautau me te tautūnga 10.

$$-\frac{4}{10}+\frac{25}{10}-\frac{3}{5}\times \frac{1}{6}$$

Tā te mea he rite te tauraro o -\frac{4}{10} me \frac{25}{10}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{-4+25}{10}-\frac{3}{5}\times \frac{1}{6}$$

Tāpirihia te -4 ki te 25, ka 21.

$$\frac{21}{10}-\frac{3}{5}\times \frac{1}{6}$$

Me whakarea te \frac{3}{5} ki te \frac{1}{6} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{21}{10}-\frac{3\times 1}{5\times 6}$$

Mahia ngā whakarea i roto i te hautanga \frac{3\times 1}{5\times 6}.

$$\frac{21}{10}-\frac{3}{30}$$

Whakahekea te hautanga \frac{3}{30} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\frac{21}{10}-\frac{1}{10}$$

Tā te mea he rite te tauraro o \frac{21}{10} me \frac{1}{10}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{21-1}{10}$$

Tangohia te 1 i te 21, ka 20.

$$\frac{20}{10}$$

Whakawehea te 20 ki te 10, kia riro ko 2.
