Tohaina
Kua tāruatia ki te papatopenga
A\times 3+4=2
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
A\times 3=2-4
Tangohia te 4 mai i ngā taha e rua.
A\times 3=-2
Tangohia te 4 i te 2, ka -2.
A=\frac{-2}{3}
Whakawehea ngā taha e rua ki te 3.
A=-\frac{2}{3}
Ka taea te hautanga \frac{-2}{3} te tuhi anō ko -\frac{2}{3} mā te tango i te tohu tōraro.
