Define the term Matrix addition/subtraction?

Expert Solution

Step 1

Matrix Addition:

Tow matrix can be added only if both matrix will be of same dimensions. It means if a matrix is of 2 by 2 then another matrix should be of 2 by 2.

In addition, simply elements are added at respective places. It can be easily understand by an example. The example of matrix addition is given as,

$\begin{array}{rcl} If two matrices are \\ A & = & [\begin{matrix} a & b \\ c & d \end{matrix}] \\ B & = & [\begin{matrix} e & f \\ g & h \end{matrix}] \\ then, addition matrix (A + B) \\ [\begin{matrix} a & b \\ c & d \end{matrix}] + [\begin{matrix} e & f \\ g & h \end{matrix}] & = & [\begin{matrix} a + e & b + f \\ c + g & d + h \end{matrix}] \end{array}$
