    What is a Determinant Calculator?

    The Determinant Calculator is a tool used to calculate the determinant of a matrix. It can handle matrices of different sizes, including 2×2, 3×3, and larger matrices. The determinant of a matrix is a scalar value that can be computed from its elements and is widely used in solving systems of linear equations, matrix inversions, and other mathematical operations.

    Matrix Input

    Enter the values of the matrix to calculate the determinant. For example, for a 2×2 matrix, input four values.

    What is a Determinant?

    The determinant of a square matrix is a number that can be computed from its elements. It plays a key role in matrix operations, especially in determining whether a system of equations has a unique solution (if the determinant is non-zero).

    How to Use the Determinant Calculator?

    To use the Determinant Calculator, simply select the matrix size (2×2, 3×3, or 4×4), enter the matrix values, and click the “Calculate Determinant” button. The result will be displayed below.

    Formula for Determinant Calculation

    The determinant of a 2×2 matrix is calculated as:

    det(A) = ad – bc, where A = [a b]
    [c d]

    For a 3×3 matrix, the formula is:

    det(A) = a(ei − fh) − b(di − fg) + c(dh − eg), where A = [a b c]
    [d e f]
    [g h i]
