10. Prove that the set of matrices of the form \[ \left(\begin{array}{lll}1 & x & y \\ 0 & 1 & z \\ 0 & 0 & 1\end{array}\right) \] is a group under matrix multiplication. This group, known as the Heisenberg group, is important in quantum physics. Matrix multiplication in the Heisenberg group is defined by \[ \left(\begin{array}{lll}1 & x & y \\ 0 & 1 & z \\ 0 & 0 & 1\end{array}\right)\left(\begin{array}{ccc}1 & x^{\prime} & y \\ 0 & 1 & z^{\prime} \\ 0 & 0 & 1\end{array}\right)=\left(\begin{array}{cc}1 & x+x^{\prime} \\ 0 & 1 \\ 0 & 0\end{array}\right) \]
