sort(-\frac{5}{20}+\frac{12}{20},9)
Ko te maha noa iti rawa atu o 4 me 5 ko 20. Me tahuri -\frac{1}{4} me \frac{3}{5} ki te hautau me te tautūnga 20.
sort(\frac{-5+12}{20},9)
Tā te mea he rite te tauraro o -\frac{5}{20} me \frac{12}{20}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
sort(\frac{7}{20},9)
Tāpirihia te -5 ki te 12, ka 7.
