How it works
Each cell in the result matrix is computed from the dot product of a row in Matrix A and a column in Matrix B.
Examples
- 2×3 × 3×2 → result is 2×2
- Use this for linear algebra practice, coordinate transforms, and matrix workflows
FAQ
- When can two matrices be multiplied?
Matrix A can be multiplied by Matrix B only when the number of columns in A equals the number of rows in B.
- What size will the result matrix be?
If A is m×n and B is n×p, the result will be m×p.
- Can I use decimals and negative values?
Yes. This calculator accepts integers, decimals, and negative values.
- Are calculations stored?
No. Everything runs locally in your browser.
