1. What is Algebraic Expression Evaluation?

Algebraic expression evaluation is the process of calculating the numerical value of a mathematical expression following the standard order of operations (PEMDAS/BODMAS rules).

2. How Does the Calculator Work?

The calculator evaluates mathematical expressions using standard arithmetic rules:

Supported operations:

• Basic arithmetic: +, -, *, /
• Parentheses: () for grouping
• Decimal numbers

Explanation: The calculator follows the standard order of operations: parentheses, exponents, multiplication/division (left to right), addition/subtraction (left to right).

3. Importance of Expression Evaluation

Details: Accurate expression evaluation is fundamental to mathematics, engineering, finance, and many scientific fields. It forms the basis for more complex calculations and problem-solving.

4. Using the Calculator

Tips: Enter a valid mathematical expression using standard operators. Use parentheses to specify the order of operations when needed. Examples: "2+3*4", "(2+3)*4", "10.5/2".

5. Frequently Asked Questions (FAQ)

Q1: What operations are supported?
