Question

Matrix method example
Explain with anyone sum..

Answer 1

Answer:

The sum of two matrices A and B will be a matrix which has the same number of rows and columns as do A and B. The sum of A and B, denoted A + B, is computed by adding corresponding elements of A and B: For example: We can also subtract one matrix from another, as long as they have the same dimensions.

Answer 2

Matrix : A matrix is an ordered rectangular array of numbers for functions. Each element in a matrix is called entries.

Order of a matrix : it is the number of rows and columns present in a matrix.

      For addition of a matrix it should satisfy two conditions, (i) it should have the same order (ii) Each element in a matrix is to be added with the corresponding element in the other matrix.

Take an example,

$A=\left[\begin{array}{ccc}a_{11}&a_{12}\\a_{21}&a_{22}\end{array}\right]_{2\times2}$

$B=\left[\begin{array}{cc}b_{11}&b_{12}\\b_{21}&b_{22}\end{array}\right]_{2\times2}$

$A+B=\left[\begin{array}{cc}a_{11}+b_{11}&a_{12}+b_{12}\\a_{21}+b_{21}&a_{22}+b_{22}\end{array}\right]$
