What are matrices?

A matrix is a rectangular array or table of numbers, symbols, or expressions arranged in rows and columns in mathematics.

The calculation of the given matrix is as follows:-

$\rm D-C= \left[\begin{array}{ccc}13&2&-5\\6&-4&0\\\end{array}\right] - \left[\begin{array}{ccc}1&4&-8\\3&-5&2\\\end{array}\right]$

$\rm D-C= \left[\begin{array}{ccc}(13-1)&(2-4)&(-5+8)\\(6-3)&(-4+5)&(0-2)\\\end{array}\right]$

$\rm D-C=\left[\begin{array}{ccc}12&-2&3\\3&1&-2\\\end{array}\right]$

Hence the final matrix will be as follows   $\rm D-C=\left[\begin{array}{ccc}12&-2&3\\3&1&-2\\\end{array}\right]$
