Find The Value Of The Determinant Calculator

Enter the elements of the matrix:


The “Find The Value Of The Determinant Calculator” is a powerful tool designed to calculate the determinant of a square matrix. Determinants play a crucial role in linear algebra and are used in various mathematical applications, including solving systems of linear equations and evaluating transformations.


The determinant of a square matrix is a scalar value that can be calculated using various methods, such as cofactor expansion or using specialized algorithms. In this calculator, the determinant is calculated using the math.js library, providing an efficient and reliable solution.

How to Use

  1. Enter the elements of the square matrix into the input field. Use commas to separate elements in a row and semicolons to separate rows (e.g., “1,2,3;4,5,6;7,8,9”).
  2. Click the “Calculate” button.
  3. View the result, which will display the calculated determinant of the entered matrix.


Suppose you want to find the determinant of the matrix:

| 1 2 3 |

| 4 5 6 |

| 7 8 9 |

Enter the matrix elements into the input field as “1,2,3;4,5,6;7,8,9,” click “Calculate,” and the result will display the determinant, which is 0 for this example.


  1. What is a determinant in linear algebra? In linear algebra, the determinant of a square matrix is a scalar value that provides important information about the matrix. It is used in various mathematical applications.
