# Determinant Calculator 4×4 + Online Solver With Free Steps

A **Determinant Calculator** is used to calculate a square matrix’s determinant, where **Determinant** represents a value with a lot of important information regarding the matrix.

This calculator can solve the determinant for a 4×4 square matrix, and it only makes it special.

## What Is a Determinant Calculator 4×4?

**A Determinant Calculator 4×4 is an online tool that can solve 4×4 order matrices to find out their determinants. **

It is a very powerful tool, as solving determinants for the **3×3 Matrix** is already so difficult. Having to solve the determinant for a **4×4 Order Matrix **almost seems impossible by hand. The calculator is very easy and intuitive to use.

## How To Use a Determinant Calculator 4×4?

To use a **Determinant Calculator 4×4**, you simply enter all the entries of your 4×4 square matrix inside the 16 input boxes available. Once done, you can simply press the “Submit” button and get results.

Use the following step-by-step guide to get the best results from this calculator:

### Step 1

First, set up a problem that you want to solve the determinant for. It may be noted that this problem must have 4×4 order.

### Step 2

### Step 4

Finally, if you would like to solve more questions of this sort, you can do so in the new interactable window.

## Solved Examples

### Example 1

Consider the given 4×4 matrix:

\[\begin{bmatrix}2 & 0 & 6 & 9 \\ 0 & 0 & 4 & 0 \\ 3 & 0 & 0 & 5 \\ 0 & 0 & -1 & 0\end{bmatrix}\]

Solve the Determinant for it.

### Solution

The Determinant result for the 4×4 square matrix is given as:

\[\begin{vmatrix}2 & 0 & 6 & 9 \\ 0 & 0 & 4 & 0 \\ 3 & 0 & 0 & 5 \\ 0 & 0 & -1 & 0\end{vmatrix} = 0\]

### Example 2

Consider the given 4×4 matrix:

\[\begin{bmatrix}-1 & 5 & 6 & 9 \\ 0 & 4 & 7 & 0 \\ 3 & -2 & 0 & 5 \\ 0 & 1 & -1 & -7\end{bmatrix}\]

Solve the Determinant for it.

### Solution

The Determinant result is given as:

\[\begin{vmatrix}-1 & 5 & 6 & 9 \\ 0 & 4 & 7 & 0 \\ 3 & -2 & 0 & 5 \\ 0 & 1 & -1 & -7\end{vmatrix} = -485\]

Therefore, this calculator can be used to compute the determinant of a 4×4 matrix in a matter of seconds.
