Kua tāruatia ki te papatopenga
2A+1=1.1
Pahekotia te A me A, ka 2A.
2A=1.1-1
Tangohia te 1 mai i ngā taha e rua.
2A=0.1
Tangohia te 1 i te 1.1, ka 0.1.
A=\frac{0.1}{2}
Whakawehea ngā taha e rua ki te 2.
A=\frac{1}{20}
Whakarohaina te \frac{0.1}{2} mā te whakarea i te taurunga me te tauraro ki te 10.
