Tohaina
Kua tāruatia ki te papatopenga
2\times 4=s+16
Me whakarea ngā taha e rua ki te 4, te tau utu o \frac{1}{4}.
8=s+16
Whakareatia te 2 ki te 4, ka 8.
s+16=8
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
s=8-16
Tangohia te 16 mai i ngā taha e rua.
s=-8
Tangohia te 16 i te 8, ka -8.
