BODMAS Calculator

Purpose-built to solve arithmetic expressions by applying BODMAS precedence rules. The engine tokenizes input, handles parentheses, and computes results with precise order of operations. It supports decimal numbers and exponentiation, and it returns a single numeric result. Conceptually, the system parses infix notation, converts to a precedence-ordered representation, and evaluates step by step to ensure correctness. Users include students, engineers, analysts, and educators who need fast validation of expressions or problem checks without pencil-and-paper work. The tool emphasizes correctness, explicit error signaling for invalid syntax, and deterministic floating-point handling, making it suitable for learning environments and professional workflows. Unique value comes from a strict adherence to BODMAS, clear error reporting, and predictable formatting of results. Core features cover input parsing, robust tokenization, a shunting-yard-based conversion, and a safe evaluator with overflow protection and division-by-zero checks. Use cases range from quick classroom checks like 3+4*(2-1) to complex nested expressions such as (2^3+5)*(4-1). Optional enhancements include unary minus handling and future extension to constants like pi. The approach remains narrowly scoped to basic arithmetic, ensuring performance and reliability across browsers and devices.
