Prime Calculator

The tool provides a robust expression evaluation engine suitable for algebra, calculus, and linear algebra. It accepts infix expressions, supports variables, user-defined constants, functions, and matrices, and returns numeric, matrix, or complex results as appropriate.
Core engine uses a parser that converts infix input to evaluation-ready form (RPN) with correct operator precedence. It supports real and complex numbers, standard mathematical functions, and a mode switch for degrees or radians. Matrix operations include creation, addition, multiplication, determinant, inverse, and row-reduction.
Audience includes students preparing for exams, educators validating results, and engineers performing quick checks in a browser. The unique value lies in a focused computation core that mirrors desktop graphing calculators, delivering fast, deterministic results and clear error information without requiring installation.
Common use cases include evaluating polynomials, solving linear systems, computing eigenvalues, performing matrix factorizations, or verifying numerical methods. Outputs adapt to the input context, returning a numeric value, a matrix, or a function value when a variable is defined.
