-\frac{1}{2}-4\left(-2\right)
Whakahekea te hautanga \frac{-2}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
-\frac{1}{2}-\left(-8\right)
Whakareatia te 4 ki te -2, ka -8.
-\frac{1}{2}+8
Ko te tauaro o -8 ko 8.
-\frac{1}{2}+\frac{16}{2}
Me tahuri te 8 ki te hautau \frac{16}{2}.
\frac{-1+16}{2}
Tā te mea he rite te tauraro o -\frac{1}{2} me \frac{16}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{15}{2}
Tāpirihia te -1 ki te 16, ka 15.
