## Introduction to Matrix Multiplication Calculator:

Matrix Multiplication Calculator is a digital tool that helps you to **find the multiplication** of two matrices in a few seconds. Our calculator is used to find the matrix multiplication for different orders but they should be compatible enough to perform matrix multiplication.

The multiplying matrices calculator is a handy tool for students, professionals, or researchers because it provides you with multiplication matrix solutions quickly and easily without any manual error in results.

## What is Matrix Multiplication?

Matrix multiplication is an important operation in linear algebra, where **two matrices are multiplied** to produce a new matrix. It uses the dot product of rows and columns process within the matrices and sum to compile the result in the order of the matrix.

## Representation of Matrix Multiplication:

The Matrix multiplication calculator presents the result of the matrix in its **mathematical form**. The Matrix multiplication is expressed as:

$$ c_{ij} \;=\; \sum_{k=1}^{n} a_{ik} . b_{kj} $$

Where:

- cij is the resulting matrix where the element of the ith row and jth column are present
- aik is the element of both row and column of matrix A.
- bkj is the element i row and column of matrix B.
- K is the sum of the index whose range is 1 for column matrix A and the rows in matrix B

## How to Calculate Matrix Multiplication?

For the **calculation of matrix multiplication**, you must know about the bases of matrices. In the multiplication of matrices, the multiply matrix calculator uses specific rules to get accurate results without indulging in a complex or lengthy matrix calculation.

Let us discuss the rules that are used by multiply matrices calculator to solve matrix multiplication.

**Step 1**:

First, the matrices multiplication calculator identifies whether the given matrices are compatible with each other or not. Here compatibility means the **number of columns** of matrix A is equal to the number of rows of another matrix B in their order.

**Step 2**:

After checking the compatibility of the matrix, the matrix multiplication calculator multiplies the first row of matrix A with all the columns (starting from the first column to the last column) of matrix B and adds the elements after multiplying.

**Step 3**:

Then, the second row of matrix A is multiplied by all the columns (starting from the first column to the last column) of matrix B.

**Step 4**:

This process continues until all the **row elements in matrix A** multiply with all the column elements of matrix B without disturbing the order of the matrix.

**Step 5**:

Lastly, the matrix multiplier calculator sums up the elements to convert the matrix into its given order for its solution.

### Matrix Multiplication 2x2

Let's see how the multiplication of matrices calculator **multiplies a matrix** that has a 2 by 2 order.

**Example**: Find the Following

$$ \biggr(\begin{matrix}2 & 4 \\ 5 & 3 \\ \end{matrix} \biggr) \biggr(\begin{matrix} 3 & 6 \\ -1 & 9 \\ \end{matrix} \biggr) $$

**Solution**:

Both the matrix has the same size which is 2 by 2.

$$ \biggr(\begin{matrix} 2 & 4 \\ 5 & 3 \\ \end{matrix} \biggr) \biggr(\begin{matrix} 3 & 6 \\ -1 & 9 \\ \end{matrix} \biggr) $$

Multiply both the matrices with the help of the above procedure of matrix multiplication

$$ \biggr(\begin{matrix} 2 \times 3 + 4 \times (-1) & 2 \times 6 + 4 \times 9 \\ 5 \times 3 + 3 \times (-1) & 5 \times 6 + 3 \times 9 \\ \end{matrix} \biggr) $$

After addition, we get the solution of the given matrix for multiplication in 2 by 2 order.

$$ =\; \biggr(\begin{matrix} 2 & 48 \\ 12 & 57 \\ \end{matrix} \biggr) $$

### Matrix Multiplication 3x3

Let's see how the matrix multiplication calculator multiplies a matrix that has 3 by 3 order which is:

$$ AB \;=\; \biggr( \begin{matrix} 1 & -3 & 2 \\ 3 & 4 & 0 \\ 5 & -4 & -1 \\ \end{matrix} \biggr) \biggr( \begin{matrix} -2 & 6 & -3 \\ 7 & 1 & 2 \\ 3 & 5 & -1 \\ \end{matrix} \biggr) $$

**Solution**:

Since both the matrix A and B has the same size which is 3 by 3. Then multiply both the matrices with the help of the above procedure of matrix multiplication

$$ =\; \begin{matrix} 1 \times -2 + -3 \times 7 + 2 \times 3 & 1 \times 6 + -3 \times 1 + 2 \times 5 & 1 \times -3 + -3 \times 2 + 2 \times -1 \\ 3 \times -2 + 4 \times 7 + 0 \times 3 & 3 \times 6 + 4 \times 1 + 0 \times 5 & 3 \times -3 + 4 \times 2 + 0 \times -1 \\ 5 \times -2 + -4 \times 7 + -1 \times 3 & 5 \times 6 + -4 \times 1 + -1 \times 5 & 5 \times -3 + -4 \times 2 + -1 \times -1 \\ \end{matrix} $$

After summation, you get the solution of the given matrix for multiplication in 3 by 3 order,

$$ =\; \biggr(\begin{matrix}-17 & 13 & -11 \\ 22 & 22 & -1 \\ -41 & 21 & -22 \\ \end{matrix} \biggr) $$
