This matrix calculator handles six standard operations on small numeric square matrices: A+B, A-B, A×B, transpose Aᵀ, determinant det(A), and inverse A⁻¹. It supports 2x2 and 3x3 sizes, accepts rows as text, and recalculates the result as valid input changes.
It is designed for introductory linear algebra, classroom exercises, homework checks, and hand-calculation review. It is not a symbolic algebra system: it does not handle variables, fraction objects, complex numbers, higher dimensions, RREF, eigenvalues, rank, norms, or matrix equations.
For Ax=b or larger systems, see the equation solver and dedicated linear-algebra tools. For symbolic numeric expressions, use the mathematical expression calculator.
The page offers six operations:
A⁻¹ such that A×A⁻¹=I, using A only.It supports 2x2 and 3x3 numeric square matrices and six operations: addition, subtraction, multiplication, transpose, determinant, and inverse.
Addition, subtraction, and multiplication use A and B; transpose, determinant, and inverse use only A.
Put one row on each line, separate values with spaces or commas, and make the row and column counts match the selected size.
When the determinant is near zero, the page treats the matrix as singular and does not return an inverse.
No. The parser accepts ordinary integer and decimal text only, and the page is fixed to 2x2 and 3x3 numeric square matrices.
Enter ordinary numeric rows to add, subtract, multiply, transpose, find determinants, or invert 2x2 and 3x3 square matrices.
