Tohaina
Kua tāruatia ki te papatopenga
2.77\times 5.43=z+12
Me whakarea ngā taha e rua ki te 5.43.
15.0411=z+12
Whakareatia te 2.77 ki te 5.43, ka 15.0411.
z+12=15.0411
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
z=15.0411-12
Tangohia te 12 mai i ngā taha e rua.
z=3.0411
Tangohia te 12 i te 15.0411, ka 3.0411.
