Tohaina
Kua tāruatia ki te papatopenga
10n\geq -29-1
Tangohia te 1 mai i ngā taha e rua.
10n\geq -30
Tangohia te 1 i te -29, ka -30.
n\geq \frac{-30}{10}
Whakawehea ngā taha e rua ki te 10. I te mea he tōrunga te 10, kāore e huri te ahunga koreōrite.
n\geq -3
Whakawehea te -30 ki te 10, kia riro ko -3.
