Kua tāruatia ki te papatopenga
9-6b>21
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa. Ka huri tēnei i te aronga o te tohu.
-6b>21-9
Tangohia te 9 mai i ngā taha e rua.
-6b>12
Tangohia te 9 i te 21, ka 12.
b<\frac{12}{-6}
Whakawehea ngā taha e rua ki te -6. I te mea he tōraro a -6, ka huri te ahunga koreōrite.
b<-2
Whakawehea te 12 ki te -6, kia riro ko -2.
