2.5-7.4+\frac{9\times 5+3}{5}
Whakareatia te -3.7 ki te 2, ka -7.4.
-4.9+\frac{9\times 5+3}{5}
Tangohia te 7.4 i te 2.5, ka -4.9.
-4.9+\frac{45+3}{5}
Whakareatia te 9 ki te 5, ka 45.
-4.9+\frac{48}{5}
Tāpirihia te 45 ki te 3, ka 48.
-\frac{49}{10}+\frac{48}{5}
Me tahuri ki tau ā-ira -4.9 ki te hautau -\frac{49}{10}.
-\frac{49}{10}+\frac{96}{10}
Ko te maha noa iti rawa atu o 10 me 5 ko 10. Me tahuri -\frac{49}{10} me \frac{48}{5} ki te hautau me te tautūnga 10.
\frac{-49+96}{10}
Tā te mea he rite te tauraro o -\frac{49}{10} me \frac{96}{10}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{47}{10}
Tāpirihia te -49 ki te 96, ka 47.
