Tohaina
Kua tāruatia ki te papatopenga
P=2S+S+S
Pahekotia te S me S, ka 2S.
P=3S+S
Pahekotia te 2S me S, ka 3S.
P=4S
Pahekotia te 3S me S, ka 4S.
P=2S+S+S
Pahekotia te S me S, ka 2S.
P=3S+S
Pahekotia te 2S me S, ka 3S.
P=4S
Pahekotia te 3S me S, ka 4S.
4S=P
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{4S}{4}=\frac{P}{4}
Whakawehea ngā taha e rua ki te 4.
S=\frac{P}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
