Kua tāruatia ki te papatopenga
A=-\frac{2}{9}-\frac{7}{9}
Ka taea te hautanga \frac{-2}{9} te tuhi anō ko -\frac{2}{9} mā te tango i te tohu tōraro.
A=\frac{-2-7}{9}
Tā te mea he rite te tauraro o -\frac{2}{9} me \frac{7}{9}, me tango rāua mā te tango i ō raua taurunga.
A=\frac{-9}{9}
Tangohia te 7 i te -2, ka -9.
A=-1
Whakawehea te -9 ki te 9, kia riro ko -1.
