Linear Algebra turns any matrix problem into a teacher-style, step-by-step solution: what each step does, why it works, plus the final answer, a back-substitution check and exam tips. Free to download – every tool works and final answers are always free. Note: the app interface and step-by-step explanations are in Simplified Chinese. Matrices, formulas and answers are standard math notation. 39 SOLVER TOOLS • Exam essentials one tap away: determinant, inverse matrix, systems of linear equations, rank, eigenvalues & eigenvectors, diagonalization, quadratic form to canonical form, reduced row echelon form (RREF). • Organized by chapter: determinants & matrix operations, elementary row operations & rank, linear systems, vector sets, eigenvalues & quadratic forms, polynomials. • Advanced matrix theory: Jordan normal form, singular value decomposition (SVD), LU decomposition, Smith normal form, full-rank factorization, Moore–Penrose pseudoinverse, least squares, matrix norms and more. STEP-BY-STEP, LIKE A TEACHER • Every elementary row operation comes with an explanation, not just a wall of matrices. • Linear systems get the complete general solution (particular solution + basis of the null space); eigenvalue problems list all eigenvectors; diagonalization gives P and Λ. • The answer card sits on top, with automatic back-substitution checks and notes on common exam points and pitfalls. STUDY CARDS 39 topics organized as key formulas → solving method → worked example → typical exam questions → common mistakes, each tagged by how often it appears on exams. Jump from any card straight into the solver to try a problem. FREE AND FULL VERSION • Free: all tools, final answers always free, 3 full step-by-step solutions per day. • Full version (one-time purchase, not a subscription): unlimited access to every step and explanation, available on all your devices signed in with the same Apple ID, with Restore Purchases.
