Kua tāruatia ki te papatopenga
\frac{5}{7}-\frac{14}{7}+0
Me tahuri te 2 ki te hautau \frac{14}{7}.
\frac{5-14}{7}+0
Tā te mea he rite te tauraro o \frac{5}{7} me \frac{14}{7}, me tango rāua mā te tango i ō raua taurunga.
-\frac{9}{7}+0
Tangohia te 14 i te 5, ka -9.
-\frac{9}{7}
Tāpirihia te -\frac{9}{7} ki te 0, ka -\frac{9}{7}.
