What works / what does not
✓ Linear equations ax + b = c with steps✓ Quadratic equations (discriminant, roots)✓ Plot y = f(x): polynomials, sin, cos, sqrt✓ Pythagoras (legs → hypotenuse), circle S and C✗ Derivatives, integrals, limits✗ Systems of equations, 3+ unknowns✗ Inequalities, intervals✗ OGE/EGE exam format — use the OGE / EGE trainer
Format: 2x + 5 = 13 or 3x - 7 = 2x + 1
Educational steps — not a full CAS like Wolfram.
