Transpose of a square matrix is a square matrix.

A column matrix has many columns and only one row.

Solve for $\mathrm{a}, \mathrm{b}$ and$\mathrm{c}$; if :

$\left[\begin{array}{cc}-4& \mathrm{a}+5\\ 3& 2\end{array}\right]=\left[\begin{array}{cc}\mathrm{h}+4& 2\\ 3& \mathrm{c}-1\end{array}\right]$

Solve for $\mathrm{a}, \mathrm{b}$ and$\mathrm{c}$; if :

$\left[\begin{array}{cc}\mathrm{a}& \mathrm{a}-\mathrm{b}\\ \mathrm{b}+\mathrm{c}& 0\end{array}\right]=\left[\begin{array}{cc}3& -1\\ 2& 0\end{array}\right]$

If $\mathrm{A}=[8-3]$and $\mathrm{B}=[4-5];$ find:

$\mathrm{A}+\mathrm{B}$

If $\mathrm{A}=[8-3]$and $\mathrm{B}=[4-5];$ find:

$\mathrm{B}-\mathrm{A}$

If $\mathrm{A}=\left[\begin{array}{c}2\\ 5\end{array}\right], \mathrm{B}=\left[\begin{array}{c}1\\ 4\end{array}\right]$ and $\mathrm{C}=\left[\begin{array}{c}6\\ -2\end{array}\right]$, find:

$\mathrm{B}+\mathrm{C}$

If $\mathrm{A}=\left[\begin{array}{c}2\\ 5\end{array}\right], \mathrm{B}=\left[\begin{array}{c}1\\ 4\end{array}\right]$ and $\mathrm{C}=\left[\begin{array}{c}6\\ -2\end{array}\right]$, find:

$\mathrm{A}-\mathrm{C}$
