compute the indicated matrices (if possible). B - C
Let
$A=\left[\begin{array}{cc}3& 0\\ -1& 5\end{array}\right],B=\left[\begin{array}{ccc}4& -2& 1\\ 0& 2& 3\end{array}\right],C=\left[\begin{array}{cc}1& 2\\ 3& 4\\ 5& 6\end{array}\right],D=\left[\begin{array}{cc}0& -3\\ -2& 1\end{array}\right],E=\left[\begin{array}{cc}4& 2\end{array}\right],F=\left[\begin{array}{c}-1\\ 2\end{array}\right]$

Given
$B=\left[\begin{array}{ccc}4& -2& 1\\ 0& 2& 3\end{array}\right],C=\left[\begin{array}{cc}1& 2\\ 3& 4\\ 5& 6\end{array}\right]$
procedure
Let A and B be any matrices , if A-B exits then order of A and B must be same.
Let A be a matrix,order of A is number of rows $×$ number of columns
Solution

here,
order of B is $2×3$
order of C is $3×2$
now, order of B is not equal to order of C
Hence B-C does not exit.
