\begin{bmatrix}{4-5} & {7-(-4)} & {} \\ {-3-3} & {8-6} & {} \\ {-5-(-1)} & {-2-8} & {}\end{bmatrix}

Step-by-step explanation:


\begin{gathered} \text{A = }\begin{bmatrix}{4} & {7} & {} \\ {-3} & {8} & {} \\ {-5} & {-2} & {}\end{bmatrix} \\ B\text{ = }\begin{bmatrix}{5} & {-4} & {} \\ {3} & {6} & {} \\ {-1} & {8} & {}\end{bmatrix} \end{gathered}

Subtracting the matrix:


\begin{gathered} To\text{ subtract matrix: } \\ \text{we take the numbers in the same position in each matrix and substract them together} \end{gathered}


A\text{ - B = }\begin{bmatrix}{4-5} & {7-(-4)} & {} \\ {-3-3} & {8-6} & {} \\ {-5-(-1)} & {-2-8} & {}\end{bmatrix}
