Frequently Asked Questions
How do I multiply two 2x2 matrices?
Enter your values in Matrix A and Matrix B, then press A × B. The calculator multiplies rows by columns: each entry of the result is the dot product of a row of A with a column of B.
What does it mean if a matrix has no inverse?
A matrix has no inverse when its determinant is zero — it is called singular. The calculator will show an error for singular matrices instead of a wrong answer.
