SUBTRACTION OF MATRICES

\[\color {purple} {Example\ 1:}\ \color {red}{If}\ A =\begin{bmatrix} 1 & 3 & 5 \\ 2 & 0 & 7 \\ 1 & 5 & 2 \\ \end{bmatrix}\ ,\ B =\begin{bmatrix} 7 & 3 & 4 \\ 1 & -1 & 5 \\ 0 & 2 & 4 \\ \end{bmatrix}\ \hspace{5cm}\]

\[\color {red}{Find\ A – B}\ \hspace{10cm}\]

\[\color {blue}{Solution:}\ A – B=\begin{bmatrix} 1 – 7 & 3 – 3 & 5 – 4 \\ 2 – 1 & 0 + 1 & 7 – 5 \\ 1 – 0 & 5 – 2 & 2 – 4 \\ \end{bmatrix}\ \hspace{6cm}\]

\[A – B=\begin{bmatrix} -6 & 0 & 1 \\ 1 & 1& 2 \\ 1 & 3 & -2 \\ \end{bmatrix}\ \hspace{7cm}\]
