Kua tāruatia ki te papatopenga
28+2p\leq 168
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa. Ka huri tēnei i te aronga o te tohu.
2p\leq 168-28
Tangohia te 28 mai i ngā taha e rua.
2p\leq 140
Tangohia te 28 i te 168, ka 140.
p\leq \frac{140}{2}
Whakawehea ngā taha e rua ki te 2. I te mea he tōrunga te 2, kāore e huri te ahunga koreōrite.
p\leq 70
Whakawehea te 140 ki te 2, kia riro ko 70.
