Matrix Addition Calculator with steps

This adding matrices calculator is a great source of knowledge for everyone who wants to evaluate matrix addition problems just by sitting at home. It not only enhances your learning capability about matrix addition methods but also increases productivity to polish your mathematical skills.

What is Matrix Addition?

Matrix addition method is used to find the summation of two or more than two matrix problems. Matrix is represented in rectangle form in which numbers are written in rows and columns. For matrix addition, it must be remembered that only the same order of matrix can be added.

For example, if the first matrix order is 3х4 and the second matrix is 2х3 then you cannot add them. It is necessary if the first matrix is 2х4 then the second matrix should have order 2х4 for addition in the matrix.

How to Find the Sum of Matrix Addition

Matrix addition has a confusing and complex procedure sometimes when you find the sum of two matrices.

To avoid confusion in your calculation of matrix addition first, you need to understand the basic rules of the matrix. Let us understand the complete calculation procedure of the add matrices calculator in steps as per the principle of the matrix.

Step 1:

First, identify the given matrices and their dimension whether they are equal or not. It must be equal to the following:

$$ Order\; of\; the\; matrix\; A \;=\; Order\; of\; matrix\; B $$

Step 2:

Start the calculating process after conferring that both the mertices have the same dimension.

Step 3:

Then take the first row and add it to the first column of the second matrix as shown in the below example.

Step 4:

Repeat this process again, take the second row of the first matrix and add it to the column and second matrix.

Step 5:

Lastly, add the row and column matrix for the solution of a given number of elements.

Practical Example of Matrix Addition

Let us see an example of matrix addition with the solution to observe the how the matrix addition calculator solves such problems.

Example:

Calculate A + B if,

$$ A \;=\; \biggr[\begin{matrix} 1 & 4 \\ 2 & 3 \\ \end{matrix} \biggr] \;and\; B \;=\; \biggr[ \begin{matrix} -4 & -1 \\ -3 & -2 \\ \end{matrix} \biggr] $$

Solution:

$$ \biggr[\begin{matrix} 1 & 4 \\ 2 & 3 \\ \end{matrix} \biggr] + \biggr[\begin{matrix} -4 & -1 \\ -3 & -2 \\ \end{matrix} \biggr] $$

$$ =\; \biggr[ \begin{matrix} (1) \; + \; (-4) & (4) \; + \; (-1) \\ (2) \; + \; (-3) & (3) \; + \; (-2) \\ \end{matrix}\biggr] \;=\; \biggr[ \begin{matrix} -3 & 3 \\ -1 & 1 \\ \end{matrix} \biggr] $$

$$ \biggr[ \begin{matrix} 1 & 4 \\ 2 & 3 \\ \end{matrix} + \biggr[ \begin{matrix} -4 & -1 \\ -3 & -1 \\ \end{matrix} \biggr] \;=\; \biggr[ \begin{matrix} -3 & 3 \\ -1 & 1 \\ \end{matrix} \biggr] $$

Frequently Ask Questions

Is matrix addition commutative?

Yes, matrix addition also has the commutative property. That means if two matrices A and B, the order in which it exist first before adding them, the order does not change the result. It can be expressed as:

$$ A + B \;=\; B + A $$

In other words, when you add matrix A to matrix B, you get the same result in the same order as the order of matrix B to matrix A. This quality tells that all matrices A and B hold this property in addition to operation if they have the same dimensions.

What are the properties of matrix addition?

The properties of matrix addition are alike the addition of real numbers. The important properties are:

Commutative property:

The dimension of addition does not matter. In other words, for any two matrices, A and B should be equal.

$$ A + B \;=\; B + A $$

Associativity property:

The group of matrices in an addition operation does not affect the result. For matrices A, B, and C the associative property is.

$$ (A + B) + C \;=\; A + (B + C) $$

Identity Element of addition:

There exists a special type of matrix, called the zero matrix or null matrix, denoted by O or 0, such that adding it to any matrix leaves the matrix unchanged. For any matrix A,

$$ A + O \;=\; O + A \;=\; A $$

Inverse Element:

For every matrix A, each matrix has its inverse −A, such that adding A and −A results in the zero matrix. In other words,

$$ A + (-A) \;=\; (-A) + A \;=\; O $$

These properties ensure that the addition of matrices satisfies certain fundamental mathematical principles, to give a solution of addition operation.

Is matrix addition associative?

Yes, matrix addition is associative. This means that when adding three matrices together, the grouping of the addition does not affect the result. Associative property can be expressed as:

$$ (A + B) + C \;=\; A + (B + C) $$

In words, if you add matrix A to matrix B first, and then add matrix C to the result, it is equivalent to adding matrix B to matrix C first, and then adding matrix A.

Associativity is a fundamental property of matrix addition, and it ensures that the order in which matrices are added together does not affect the final result.

Can you add matrices with different dimension?

No, You cannot directly add matrices with different dimensions. Matrix addition is only defined for those matrices that have the same size. That means every matrix must have the same number of rows and the same number of columns.

If you attempt to add matrices with different dimensions, it would become lengthy or confusing, which is not valid for matrix operation.

For example, you can easily add a 2x2 matrix to another 2x2 matrix, or a 3x3 matrix to another 3x3 matrix, but you cannot add a 2x2 matrix into a 3x3 matrix directly.

What is an example of an additive identity matrix?

An additive identity matrix is also known as a zero matrix or null matrix. It is a special matrix that, when added to any other matrix, leaves the other matrix unchanged. An additive identity matrix is a null matrix filled with zeros. For example, let's consider a 2x2 zero matrix:

$$ O \;=\; [0\; 0\; 0\; 0] $$

Adding this zero matrix O to any 2x2 matrix A will result in A itself:

$$ A + O \;=\; O + A \;=\; A $$

So, in this case, the 2x2 zero matrix serves as the additive identity for 2x2 matrices. Similarly, for matrices of any other size, the zero matrix of that size would represent as the additive identity.
