About

In the fields of engineering, physics, and advanced academics, accuracy in calculation is not just a preference; it is a necessity. A misplaced bracket or a misunderstood order of operations can lead to structural failures or incorrect experimental data. This Advanced Math Expression Evaluator is designed for students and professionals who need to verify complex arithmetic strings that go beyond simple addition and subtraction.

Unlike standard calculators that execute operations immediately, this tool parses the entire expression, respecting the hierarchy of mathematical logic (PEMDAS/BODMAS). It handles nested parentheses, square roots, and exponentiation simultaneously, ensuring that the syntax of your equation is interpreted exactly as intended in formal mathematics.

Formulas

The evaluator follows the standard Order of Operations:

Result = Evaluate( Expression )

It processes components in this strict sequence:

Step 1. Parentheses ( ) and Functions.
Step 2. Exponents xⁿ and Roots √x.
Step 3. Multiplication × and Division ÷ (Left to Right).
Step 4. Addition + and Subtraction − (Left to Right).

Reference Data

Operator	Symbol/Syntax	Precedence	Example
Parentheses	`( ... )`	1 (Highest)	`2 * (3 + 5)`
Functions	`sqrt(x)`, `sin(x)`	2	`sqrt(16) + sin(90)`
Exponents	`^`	3	`2^3` → 8
Multiplication	`*`	4	`5 * 4`
Division	`/`	4	`20 / 2`
Addition	`+`	5	`10 + 2`
Subtraction	`-`	5	`10 - 2`
Constants	`pi`, `e`	N/A	`2 * pi`

Frequently Asked Questions

Syntax errors usually occur due to mismatched parentheses or missing operators. For example, writing '2(3+4)' is implied multiplication in handwriting, but many parsers require an explicit asterisk: '2*(3+4)'. Check that every opening bracket has a closing one.

Yes. You can input negative exponents using the caret symbol and parentheses for clarity. For instance, '2^(-3)' will correctly evaluate to 0.125.

This specific version focuses on algebraic structures (roots, powers, basic arithmetic). While it supports constants like pi, trigonometric functions should be pre-calculated or used in our dedicated scientific calculator.

Division by zero is mathematically undefined. The tool detects this condition and will return 'Infinity' or an error message, preventing invalid results in your calculations.
