## Quick Answer

Multiply two matrices and see each step. Enter matrix A and matrix B; the calculator checks that A's columns equal B's rows, then returns the product matrix with the dot-product breakdown for each entry.

## Definition

A matrix multiplication calculator computes the product of two matrices. Two matrices can be multiplied only when the number of columns in the first equals the number of rows in the second; the resulting matrix has the row count of the first and the column count of the second. Each entry of the product is the dot product of a row from the first matrix and a column from the second. Students and engineers use it for linear algebra, transformations, and systems of equations.

## How to Use

1. **Set the dimensions** — Choose the size of matrix A and matrix B. A's column count must equal B's row count.
2. **Enter the values** — Type each number into matrix A and matrix B.
3. **Multiply** — Read the product matrix and the row-by-column breakdown for each entry.
