Adds Matrix in this form $\begin{vmatrix} a_{11} \ a_{12} \\ a_{21} \ a_{22} \end{vmatrix} \begin{vmatrix} b_{11} \ b_{12} \\ b_{21} \ b_{22} \end{vmatrix}$

Matrix addition calculator simplify with step by step solution an operation performed on two matrices of the same size, where each corresponding element of the matrices is added together to create a new matrix.

### matrix A Element

Enter all the element of A like so a11, a12, a21, a22

### Matrix B

Enter all the element of B like so b11, b12, b21, b22

Hit the check to calculate Matrix addition

Matrix addition is an operation performed on matrices, which are rectangular arrays of numbers or symbols arranged in rows and columns. It involves adding corresponding elements of two matrices to obtain a new matrix with the same dimensions.

To perform matrix addition, the two matrices being added must have the same number of rows and columns. The addition is done by adding the elements in the same position in each matrix. For example, if we have two matrices A and B, and we want to add them to obtain matrix C, the addition is done as follows:

• C[ i ][ j ] = A[ i ][ j ] + B[ i ][ j ]

where C[i][j] represents the element in the i-th row and j-th column of matrix C, A[i][j] represents the element in the i-th row and j-th column of matrix A, and B[i][j] represents the element in the i-th row and j-th column of matrix B.

Matrix addition is commutative, which means that the order of addition does not affect the result. It is also associative, meaning that the grouping of matrices being added does not affect the result. These properties make matrix addition a fundamental operation in linear algebra and various other fields of mathematics and science.

Matrix addition can be used in various applications, such as solving systems of linear equations, performing transformations in computer graphics, and analyzing data in statistics. It allows for the combination of different matrices to obtain new matrices that represent meaningful information or relationships between variables.
