Example:

A=[2314],B=[5201]A = \begin{bmatrix} 2 & 3 \\ 1 & 4 \end{bmatrix}, B = \begin{bmatrix} 5 & 2 \\ 0 & 1 \end{bmatrix}A=[21​34​],B=[50​21​]

• Addition: A+B=[7515]A + B = \begin{bmatrix} 7 & 5 \\ 1 & 5 \end{bmatrix}A+B=[71​55​]

• Subtraction: A−B=[−3113]A – B = \begin{bmatrix} -3 & 1 \\ 1 & 3 \end{bmatrix}A−B=[−31​13​]

Tools like Add matrices calculator and Subtract matrices calculator perform this instantly.

Matrix Multiplication

A Matrix multiplication calculator can handle multiplication between square or rectangular matrices.

Rule: If $A$ is $m\times n$ and $B$ is $n\times p$, the resulting matrix is $m\times p$.

Example:

A=[1234],B=[2013]A = \begin{bmatrix} 1 & 2 \\ 3 & 4 \end{bmatrix}, B = \begin{bmatrix} 2 & 0 \\ 1 & 3 \end{bmatrix}A=[13​24​],B=[21​03​] A×B=[461012]A \times B = \begin{bmatrix} 4 & 6 \\ 10 & 12 \end{bmatrix}A×B=[410​612​]

Tools like Multiply matrices calculator and Matrix multiplication online simplify this process.

Determinant of a Matrix

The determinant provides insight into the matrix’s properties (invertibility, area scaling).

• 2×2 matrix determinant calculator: det[abcd]=ad−bcdet\begin{bmatrix}a & b \\ c & d\end{bmatrix} = ad – bcdet[ac​bd​]=ad−bc

• 3×3 matrix determinant calculator: Uses expansion by minors.

• Determinant calculator 4×4: Handles larger matrices effortlessly.

A Matrix determinant online tool gives instant results and often shows Matrix determinant step by step.

Matrix Inverse

The inverse is crucial for solving linear equations.

• 2×2 matrix inverse calculator formula:

A−1=1det(A)[d−b−ca]A^{-1} = \frac{1}{det(A)} \begin{bmatrix} d & -b \\ -c & a \end{bmatrix}A−1=det(A)1​[d−c​−ba​]

• 3×3 matrix inverse calculator: Uses cofactor and adjoint methods.

Online calculators like Matrix inverse calculator and Inverse matrix calculator online make this process fast and accurate.

Matrix Transpose

Transpose flips a matrix along its diagonal.

• Matrix transpose online or Transpose a matrix calculator swaps rows with columns.

Example:

A=[123456]  ⟹  AT=[142536]A = \begin{bmatrix} 1 & 2 & 3 \\ 4 & 5 & 6 \end{bmatrix} \implies A^T = \begin{bmatrix} 1 & 4 \\ 2 & 5 \\ 3 & 6 \end{bmatrix}A=[14​25​36​]⟹AT=​123​456​​
