Whakaoti mō c
\left\{\begin{matrix}c=\frac{s}{h}\text{, }&h\neq 0\\c\in \mathrm{R}\text{, }&s=0\text{ and }h=0\end{matrix}\right.
Whakaoti mō h

ch=s
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
hc=s
He hanga arowhānui tō te whārite.
\frac{hc}{h}=\frac{s}{h}
Whakawehea ngā taha e rua ki te h.
c=\frac{s}{h}
Mā te whakawehe ki te h ka wetekia te whakareanga ki te h.
ch=s
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{ch}{c}=\frac{s}{c}
Whakawehea ngā taha e rua ki te c.
h=\frac{s}{c}
Mā te whakawehe ki te c ka wetekia te whakareanga ki te c.
