10h-30-7\left(h+7\right)>4h
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te 2h-6.
10h-30-7h-49>4h
Whakamahia te āhuatanga tohatoha hei whakarea te -7 ki te h+7.
3h-30-49>4h
Pahekotia te 10h me -7h, ka 3h.
3h-79>4h
Tangohia te 49 i te -30, ka -79.
3h-79-4h>0
Tangohia te 4h mai i ngā taha e rua.
-h-79>0
Pahekotia te 3h me -4h, ka -h.
-h>79
Me tāpiri te 79 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
h<-79
Whakawehea ngā taha e rua ki te -1. I te mea he tōraro a -1, ka huri te ahunga koreōrite.
