Tohaina
Kua tāruatia ki te papatopenga
-\frac{1}{4}+8
Ko te tauaro o -8 ko 8.
-\frac{1}{4}+\frac{32}{4}
Me tahuri te 8 ki te hautau \frac{32}{4}.
\frac{-1+32}{4}
Tā te mea he rite te tauraro o -\frac{1}{4} me \frac{32}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{31}{4}
Tāpirihia te -1 ki te 32, ka 31.
