*Matrix Addition Calculator*is an online tool programmed to perform matrix addition between the two 3x3 matrices A and B. A general formula shown below notice that the indices match for the elements that combine, and that matrix addition is commutative; e.g (A + B = B + A). Matrix addition can undergo operations according to specific rules, just as numbers and symbols do in simple algebra

### What is 3x3 Matrix?

A 3x3 matrix is a rectangular often square array of numbers having 3 columns and 3 rows, or expressions which can be evaluated to numbers. The dimensions m x n refer to the number of rows (m) and columns (n) respectively. The individual values constituting a matrix are called its elements, usually referred to by their row and column numbers, called indices. Matrices have a variety of uses in chemistry, from curve fitting and quantum mechanics to group theory and molecular graphics. There are specific restrictions on the dimensions of matrices that can be added. In the matrix addition A and B, the number of columns in matrix A must be equal to the number of rows in matrix B. The resulting matrix addition will have the same number of rows as matrix A and the same number of columns as B

### 3x3 Matrix Addition Formula

Matrices are widely used in geometry, physics and computer graphics applications. The array of quantities or expressions set out by rows and columns; treated as a single element and manipulated according to rules. Matrix calculations can be understood as a set of tools that involves the study of methods and procedures used for collecting, classifying, and analyzing data. In many applications it is necessary to calculate the matrix addition where this online matrix addition calculator can help you to effortlessly make your calculations easy for the respective inputs
