Matrix addition is the basic operation of adding two matrices with the corresponding entries.
Two matrices must have an equal number of rows and columns.
The sum of matrices A and B is denoted by Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle A+B= \begin{bmatrix} a_{11} & a_{12}&\cdots & a_{1n} \\ a_{21}& a_{22}& \cdots & a_{2n} \\ \vdots & \ddots & \vdots \\ a_{m1} & a_{m2}& \cdots & a_{mn} \end{bmatrix} +\begin{bmatrix} b_{11} & b_{12}&\cdots & b_{1n} \\ b_{21}& b_{22}& \cdots & b_{2n} \\ \vdots & \ddots & \vdots \\ b_{m1} & b_{m2}& \cdots & b_{mn} \end{bmatrix} = \begin{bmatrix} a_{11}+b_{11} & a_{12}+b_{12}&\cdots & a_{1n}+b_{1n} \\ a_{21}+b_{21}& a_{22}+b_{22}& \cdots & a_{2n}+b_{2n} \\ \vdots & \ddots & \vdots \\ a_{m1}+b_{m1} & a_{m2}+b_{m2}& \cdots & a_{mn}+b_{mn} \end{bmatrix} *Here <matrix>afactor} constant value is multiplied with each values in matrix A and Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle bfactor} constant value is multiplied with each values in matrix B.
Then it is doing the matrix addition with all the corresponding entries.
If the factor values are not given then it is doing usual matrix addition with the factor values as 1.
