List of top Higher Mathematics Questions on Matrices

What is column matrix?
If \( A = \begin{pmatrix} -2 & 3 \\ 1 & 2 \end{pmatrix} \) and \( B = \begin{pmatrix} -1 & 0 \\ 1 & 2 \end{pmatrix} \), then find \( (A + B) \).
If \( A = \begin{pmatrix} 1 & -4 \\ 3 & 3 \end{pmatrix} \) and \( B = \begin{pmatrix} -1 & 2 \\ 1 & 2 \end{pmatrix} \), then find \( AB \).
If \( A = [a_{ij}]_{m \times n} \) and \( B = [b_{ij}]_{j \times p} \), then order of \( AB \) will be \( m \times p \).
