-\frac{6+1}{3}+\frac{1}{9}
Whakareatia te 2 ki te 3, ka 6.
-\frac{7}{3}+\frac{1}{9}
Tāpirihia te 6 ki te 1, ka 7.
-\frac{21}{9}+\frac{1}{9}
Ko te maha noa iti rawa atu o 3 me 9 ko 9. Me tahuri -\frac{7}{3} me \frac{1}{9} ki te hautau me te tautūnga 9.
\frac{-21+1}{9}
Tā te mea he rite te tauraro o -\frac{21}{9} me \frac{1}{9}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
-\frac{20}{9}
Tāpirihia te -21 ki te 1, ka -20.
