887-7d\geq 873
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa. Ka huri tēnei i te aronga o te tohu.
-7d\geq 873-887
Tangohia te 887 mai i ngā taha e rua.
-7d\geq -14
Tangohia te 887 i te 873, ka -14.
d\leq \frac{-14}{-7}
Whakawehea ngā taha e rua ki te -7. I te mea he tōraro a -7, ka huri te ahunga koreōrite.
d\leq 2
Whakawehea te -14 ki te -7, kia riro ko 2.
