Quick guide

How to use this calculator

  1. Choose an operation.
  2. Set the dimensions of matrices A and B.
  3. Fill every entry and read the exact result matrix.

Calculation method

Use the rule selected for A and B

Addition, subtraction, and the Hadamard product combine matching entries. Matrix multiplication instead takes dot products of rows of A with columns of B, so order and dimensions matter.

Worked example

Add two 2 × 2 matrices

For A = [[1,2],[3,4]] and B = [[5,6],[7,8]], add corresponding entries.

A + B = [[6,8],[10,12]]

Supported inputs

Precision and limits

Matrix size

Each input matrix may contain 1–6 rows and 1–6 columns.

Entry precision

Each signed decimal may contain up to 30 digits and 15 decimal places.

Exactness

Finite decimals are converted to reduced fractions before calculation; matrix arithmetic is not rounded.
