Tohaina
Kua tāruatia ki te papatopenga
s\times 0=0
Whakareatia ngā taha e rua o te whārite ki te z.
0=0
Ko te tau i whakarea ki te kore ka hua ko te kore.
\text{true}
Whakatauritea te 0 me te 0.
s\in \mathrm{R}
He pono tēnei mō tētahi s ahakoa.
s\times 0=0

0=0
Ko te tau i whakarea ki te kore ka hua ko te kore.
\text{true}
