Conditions for the subtraction of matrices:
1. Two matrices should be of the same order (number of rows=number of columns).
2. Subtract the corresponding element of other matrices.
Given, $P = [\begin{matrix} 4 & 3 & 2 \end{matrix}]$ and
$Q = [\begin{matrix} - 1 & 2 & 3 \end{matrix}]$
Therefore,
$P - Q = [432] - [- 123] = [51 - 1]$

If P=[432] and Q=[−123], then P−Q=[51−1][5−1−4][511][−4−16]

Conditions for the subtraction of matrices:1. Two matrices should be of the same order (number of rows=number of columns).2. Subtract the corresponding element of other matrices.Given, P=[432] andQ=[−123] Therefore,P−Q=[4 3 2]−[−1 2 3]=[5 1 −1]

If $P = [\begin{matrix} 4 & 3 & 2 \end{matrix}]$ and $Q = [\begin{matrix} - 1 & 2 & 3 \end{matrix}],$ then $P - Q =$
$[\begin{matrix} 5 & 1 & - 1 \end{matrix}]$
$[\begin{matrix} 5 & - 1 & - 4 \end{matrix}]$
$[\begin{matrix} 5 & 1 & 1 \end{matrix}]$
$[\begin{matrix} - 4 & - 1 & 6 \end{matrix}]$
