## Introduction to matrix determinant calculator

A matrix determinant calculator is an online tool to calculate the determinant of the matrix to find the scalar value. It uses the expansion method to find a single value of a square matrix. It also uses the reduction method and finds the scalar value.

We usually apply addition, subtraction, and multiplications in matrix algebra on the matrices. The determinant is necessary to calculate the unique solution of the system of nonlinear equations. That’s why we introduce matrix determinant calculator 3x3 with steps that can easily calculate determinants using both methods of expansion and reduction.

## Formula used by matrix determinant formula calculator

This matrix determinant calculator with steps uses two formulas to calculate the determinant of a matrix of order 2, 3 or 4. These are:

1. The determinant plays an important role to solve the system of linear equations and to find the inverse of matrix, then the determinant of 2×2 matrix is:

$$A \;=\; \begin{bmatrix} a & b \\ c & d \end{bmatrix}$$ $$|A| \;=\; \begin{vmatrix} a & b \\ c & d \end{vmatrix} \;=\; (a \times c) \;-\; (b \times d)$$
2. If A is the determinant of the matrix A than the determinant for 3×3 matrix.

$$\begin{bmatrix} a & b & c \\ d & e & f \\ g & h & i \\ \end{bmatrix}$$ $$\begin{vmatrix} a & b & c \\ d & e & f \\ g & h & i \\ \end{vmatrix}$$ $$|A| \;=\; a \begin{vmatrix} e & f \\ h & i \end{vmatrix} \;-\; b \begin{vmatrix} d & f \\ g & i \end{vmatrix} \;-\; c \begin{vmatrix} d & e \\ g & h \end{vmatrix}$$
3. The determinant for 4-by-by matrix can be solved by reducing its row of a column or reducing the matrix to triangular form.

## How to use the matrix 4x4 determinant calculator?

This determinant matrix calculator can be used by following below steps:

1. In the first step, you need to enter the number of rows and columns for the matrix.
2. Now put the values of all elements of the matrix.
3. Or you can use the random button to select the random matrix.
4. Now click on the calculate button.

You will get the solution within a few seconds of clicking on the calculate button. Determinant of a matrix calculator will give you a step-by-step solution so that you can use to learn and practice.

## Why use determinant matrix calculator?

In mathematics, the matrix is important to solve the system of linear equations. Some operations are applied to solve a system of linear equations. So, the determinant is an important operation. You can use the matrix determinant solver to solve many problems.

While you are computing the determinant of the higher-order matrix, you cannot solve it with expansion only. You have to reduce the order of the matrix by using a reduced echelon form, which is a tricky procedure.

So there is a need for a determinant of 4x4 matrix calculator with steps that can easily reduce the demand for the matrix. That’s why you need to use a matrix determinant finder that is helpful for you to find the determinant of the 2x2 matrix.

## Benefits of using determinant calculator with steps
