Kua tāruatia ki te papatopenga
\frac{-5}{2}+5\times 3
Whakareatia te -5 ki te \frac{1}{2}, ka \frac{-5}{2}.
-\frac{5}{2}+5\times 3
Ka taea te hautanga \frac{-5}{2} te tuhi anō ko -\frac{5}{2} mā te tango i te tohu tōraro.
-\frac{5}{2}+15
Whakareatia te 5 ki te 3, ka 15.
-\frac{5}{2}+\frac{30}{2}
Me tahuri te 15 ki te hautau \frac{30}{2}.
\frac{-5+30}{2}
Tā te mea he rite te tauraro o -\frac{5}{2} me \frac{30}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{25}{2}
Tāpirihia te -5 ki te 30, ka 25.
