Kua tāruatia ki te papatopenga
\frac{7}{4}-\frac{5}{2}+3
Me tahuri ki tau ā-ira 2.5 ki te hautau \frac{25}{10}. Whakahekea te hautanga \frac{25}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
\frac{7}{4}-\frac{10}{4}+3
Ko te maha noa iti rawa atu o 4 me 2 ko 4. Me tahuri \frac{7}{4} me \frac{5}{2} ki te hautau me te tautūnga 4.
\frac{7-10}{4}+3
Tā te mea he rite te tauraro o \frac{7}{4} me \frac{10}{4}, me tango rāua mā te tango i ō raua taurunga.
-\frac{3}{4}+3
Tangohia te 10 i te 7, ka -3.
-\frac{3}{4}+\frac{12}{4}
Me tahuri te 3 ki te hautau \frac{12}{4}.
\frac{-3+12}{4}
Tā te mea he rite te tauraro o -\frac{3}{4} me \frac{12}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{9}{4}
Tāpirihia te -3 ki te 12, ka 9.
