Algebra Calculators
Factors, quadratics, regression and limits.
Four tools covering the algebra that appears most often in secondary and early undergraduate work. Each shows its working rather than only the answer, because in almost every case the method is what is being assessed.
GCF and LCM calculatorGreatest common factor, LCM, prime factorisation
Quadratic formula calculatorRoots, discriminant, vertex and axis of symmetry
Quadratic regression calculatorLeast-squares parabola through your data, with R squared
Limit calculatorNumerical limits from the left, the right, or both
