Matrix Calculator

How to Use

This tool performs mathematical operations on 3x3 matrices. Enter numbers into the grid cells to create matrices, then use operation buttons to calculate results. • Click in any cell of Matrix A or Matrix B and type numbers (decimals allowed) • Use "Clear A", "Clear B", or "Clear R" buttons to reset specific matrices • Click operation buttons to perform calculations: - A + B = R: adds matrices A and B - A * B = R: multiplies matrix A by matrix B - B * A = R: multiplies matrix B by matrix A (order matters) - adj(A) = R: finds adjugate of matrix A - inv(A) = R: calculates inverse of matrix A - inv(B) = R: calculates inverse of matrix B • Click "det(A)" or "det(B)" to calculate determinants • Use ReArrange buttons to copy values between matrices (R→A, A→B, etc.) • Results appear in the Resultant Matrix (R) section • Leave cells empty if your matrix is smaller than 3x3
