How the Matrix Calculator Works

The calculator works by accepting matrix entries as inputs and applying standard mathematical formulas for the chosen operation:

Addition/Subtraction: Adds or subtracts corresponding elements
Multiplication: Uses row-by-column multiplication
Determinant: Uses recursive expansion or row reduction
Inverse: Uses Gauss-Jordan elimination or adjoint method
Transpose: Flips rows into columns

The result is instantly displayed in a readable format, often with intermediate steps shown in advanced calculators.

How to Use the Matrix Calculator (Step-by-Step)

Step 1: Enter Matrix Dimensions

Specify the number of rows and columns for your matrices.

Step 2: Input Matrix Elements

Enter the numbers for each cell in the matrix.

Step 3: Select Operation

Choose the operation you want to perform: addition, subtraction, multiplication, determinant, inverse, etc.

Step 4: Calculate

Click “Calculate” to see the result instantly.

Step 5: Optional – Reset

Clear the matrices to perform another calculation.

Matrix Calculator Examples

Example 1 – Matrix Addition

Matrix A:
$\begin{bmatrix} 1 & 2 \\ 3 & 4 \end{bmatrix}$ [1324]

Matrix B:
$\begin{bmatrix} 5 & 6 \\ 7 & 8 \end{bmatrix}$ [5768]

Result:
$\begin{bmatrix} 6 & 8 \\ 10 & 12 \end{bmatrix}$ [610812]

Example 2 – Matrix Multiplication

Matrix A:
$\begin{bmatrix} 1 & 2 \\ 3 & 4 \end{bmatrix}$ [1324]

Matrix B:
$\begin{bmatrix} 2 & 0 \\ 1 & 2 \end{bmatrix}$ [2102]

Result:
$\begin{bmatrix} 4 & 4 \\ 10 & 8 \end{bmatrix}$ [41048]

Example 3 – Determinant

Matrix A:
$\begin{bmatrix} 3 & 2 \\ 1 & 4 \end{bmatrix}$ [3124]

Determinant: $(3×4) - (2×1) = 10$ (3×4)−(2×1)=10
