52z-118-36z<-22
Tangohia te 36z mai i ngā taha e rua.
16z-118<-22
Pahekotia te 52z me -36z, ka 16z.
16z<-22+118
Me tāpiri te 118 ki ngā taha e rua.
16z<96
Tāpirihia te -22 ki te 118, ka 96.
z<\frac{96}{16}
Whakawehea ngā taha e rua ki te 16. I te mea he tōrunga te 16, kāore e huri te ahunga koreōrite.
z<6
Whakawehea te 96 ki te 16, kia riro ko 6.
