Find the given elements of matrix D<br> Please help!!!

TEA [102]

Answer:

Element wise subtraction.

Step-by-step explanation:

Matrix Subtraction is done element wise.

Therefore, D = $\left[ {\begin{array}{ccc} 3 & 1 & 0 \\ -1 & 2 & 4 \\9 & 7 & -2 \end{array} } \right]$ - $\left[ {\begin{array}{ccc} 5 & 2 & -4\\ 1 & 12 & 3 \\ 11 & 3 & -2 \end{array} } \right]$

This becomes:

$D = \left[ {\begin{array}{ccc} -2 & -1 & 4 \\ -2 & -10 & 1 \\ -2 & 4 & 0 \end{array} } \right]$

Now, $d_{11} = -2$

$d_{12} = -1$

$d_{13} = 4$

$d_{21} = -2$

$d_{22} = -10$

$d_{31} = -2$
