High School Calculator

This tool evaluates arithmetic and basic algebra expressions entered as a single field. It supports operators +, -, *, /, ^, parentheses, and decimal numbers. Example expressions include 2*(3+4)/5 and (1+2.5)^2. It returns a numeric result with configurable precision and no units.
Conceptually, the engine tokenizes the input, applies operator precedence, converts the tokens to a computational form, and evaluates the result using a stable double-precision backend. It detects malformed syntax, misbalanced parentheses, and attempts to divide by zero, signaling errors without producing a numeric output.
Who benefits: students performing homework checks, teachers delivering quick drills, and tutors guiding problem solving. Unique value includes fast, reliable evaluation in a lightweight environment, consistent rounding, and strict input validation that reduces the need for external calculators.
Core features and use cases: one-input evaluation for practice sessions, precision control for classroom demonstrations, and immediate checks of given solutions. Optional features include step-by-step explanations, a short result history, and a basic problem generator to support ongoing instruction.
This tool adheres to standard US numeric conventions by default and does not perform unit conversions or symbolic algebra. It is designed to complement math curricula and remote learning, helping learners verify work quickly and teachers assess students\' work with minimal setup.
