-\frac{13}{4}-\frac{1\times 8+5}{8}
Tāpirihia te 8 ki te 5, ka 13.
-\frac{13}{4}-\frac{8+5}{8}
Whakareatia te 1 ki te 8, ka 8.
-\frac{13}{4}-\frac{13}{8}
Tāpirihia te 8 ki te 5, ka 13.
-\frac{26}{8}-\frac{13}{8}
Ko te maha noa iti rawa atu o 4 me 8 ko 8. Me tahuri -\frac{13}{4} me \frac{13}{8} ki te hautau me te tautūnga 8.
\frac{-26-13}{8}
Tā te mea he rite te tauraro o -\frac{26}{8} me \frac{13}{8}, me tango rāua mā te tango i ō raua taurunga.
-\frac{39}{8}
Tangohia te 13 i te -26, ka -39.
