What This Calculator Does

This page is best for one clear job: quickly checking standard operations on small square matrices. For class exercises, introductory linear algebra, homework verification, and interview review, 2x2 and 3x3 cases already cover many of the matrices people handle by hand. You do not need a large symbolic system just to confirm a result.

The page is not trying to be a general-purpose computer algebra tool. It is a text-input calculator for small matrices, which is why it focuses on fast entry, clear operation choices, and immediate result checking instead of higher-dimensional or advanced matrix workflows.

When to Use It

  • You need quick arithmetic on 2x2 or 3x3 square matrices.
  • You want to check a determinant, inverse, or transpose.
  • You would rather paste matrix text than fill cells one by one.
  • You want an instant homework or revision cross-check.

Inputs Explained

Operation

The current page supports six operations.

  • Addition
  • Subtraction
  • Multiplication
  • Determinant
  • Inverse
  • Transpose

The first three require both matrix A and matrix B. The last three require only matrix A.

Frequently Asked Questions

Which matrix sizes does the current page support?

The current page supports 2x2 and 3x3 square matrices only.

Which operations need two matrices?

Addition, subtraction, and multiplication need both matrix A and matrix B, while determinant, inverse, and transpose use only matrix A.

How should I enter the matrix text?

Put each row on its own line and separate values with spaces or commas, making sure the row and column count matches the selected size.

Why does inverse sometimes fail?

If the matrix is singular, meaning its determinant is 0, the current page cannot produce an inverse result.
