\left(-m\right)m-\left(-m\right)n-nm+n^{2}
Me hoatu te āhuatanga tohatoha mā te whakarea ia tau o -m-n ki ia tau o m-n.
\left(-m\right)m+mn-nm+n^{2}
Whakareatia te -1 ki te -1, ka 1.
\left(-m\right)m+n^{2}
Pahekotia te mn me -nm, ka 0.
-m^{2}+n^{2}
Whakareatia te m ki te m, ka m^{2}.
\left(-m\right)m-\left(-m\right)n-nm+n^{2}
Me hoatu te āhuatanga tohatoha mā te whakarea ia tau o -m-n ki ia tau o m-n.
\left(-m\right)m+mn-nm+n^{2}
Whakareatia te -1 ki te -1, ka 1.
\left(-m\right)m+n^{2}
Pahekotia te mn me -nm, ka 0.
-m^{2}+n^{2}
Whakareatia te m ki te m, ka m^{2}.
