calculate

Deterministic math for AI agents.

Every AI model predicts mathematical answers by generating the most likely next token. Euclid's calculate tool evaluates expressions with a real math engine. Arithmetic, percentages, exponents, roots, trigonometry, logarithms, factorials. The answer is exact, every time.
