Determinant Calculator
determinant calculator. Get instant, accurate results. Enter values for instant results with step-by-step formulas.
Formula
2x2: det = ad - bc | 3x3: det = a(ei-fh) - b(di-fg) + c(dh-eg)
The determinant is a scalar value computed from a square matrix. For 2x2: ad-bc. For 3x3: cofactor expansion along the first row. Determinant = 0 means the matrix is singular (no inverse, zero volume).
