50-150p-250p=10
Tangohia te 250p mai i ngā taha e rua.
50-400p=10
Pahekotia te -150p me -250p, ka -400p.
-400p=10-50
Tangohia te 50 mai i ngā taha e rua.
-400p=-40
Tangohia te 50 i te 10, ka -40.
p=\frac{-40}{-400}
Whakawehea ngā taha e rua ki te -400.
p=\frac{1}{10}
Whakahekea te hautanga \frac{-40}{-400} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -40.
