Given the matrices A=[032305]\displaystyle {A}={\left[\begin{array}{ccc} {0}&{3}&{2}\\{3}&{0}&{5}\end{array}\right]} and B=[521143503]\displaystyle {B}={\left[\begin{array}{ccc} {5}&{2}&-{1}\\{1}&-{4}&{3}\\-{5}&{0}&-{3}\end{array}\right]}

A. It is to subtract these two matrices.

B. If subtraction is possible what is AB\displaystyle {A}-{B}
