What is a Matrix Calculator?
A Matrix Calculator is a digital tool that lets you perform operations on matrices—most commonly addition and subtraction. A matrix is a rectangular array of numbers arranged in rows and columns. It’s widely used in subjects like algebra, computer science, physics, and engineering.
With our online Matrix Calculator, you can:
Add two 3×3 matrices
Subtract one 3×3 matrix from another
Handle positive and negative numbers
Display results in an easy-to-read grid format
View multiple calculations without losing previous results
How to Use the Matrix Calculator
Using the Matrix Calculator is simple and user-friendly. Here’s how to get started:
Enter values into Matrix A (left side).
Enter values into Matrix B (right side).
Click either “Add Matrices” or “Subtract Matrices” depending on the operation you need.
Instantly see the result below, formatted as a clean and colorful widget.
Each result is saved on the page until you hit the “Clear” button, which resets the calculator. This means you can perform multiple calculations back-to-back and compare your results visually.
