Algebra & Functions calculators
Algebra is a sequence of small, legal moves. The hard part is knowing which move comes next — and being able to prove that the answer is right.
These tools make the sequence visible. The scientific calculator reduces your expression one operation at a time in the order brackets, exponents, multiplication/division, then addition/subtraction. The equation solvers finish with a substitution check so you can trust the result.

Questions about this category
Does the scientific calculator work in degrees and radians?
Yes. Switch the DEG/RAD toggle above the keypad. Trig steps always state which unit was used.
Can the solvers handle complex roots?
The quadratic solver reports complex roots when the discriminant is negative, written in the form a ± bi.
