1. What is Order of Operations?

The order of operations is a collection of rules that reflect conventions about which procedures to perform first when evaluating a given mathematical expression.

2. How Does the Calculator Work?

The calculator follows standard mathematical precedence rules:

Example: In the expression (2+3)*4, the parentheses are evaluated first (2+3=5), then multiplication (5*4=20).

3. Parentheses Evaluation

Details: Parentheses can be nested, and the calculator will evaluate the innermost parentheses first, working outward.

4. Using the Calculator

Tips: Enter any valid mathematical expression using numbers, +, -, *, /, ^ (exponent), and parentheses. Example: (3+5)*2^3/4

5. Frequently Asked Questions (FAQ)

Q1: What operators are supported?
A: Basic arithmetic (+, -, *, /), exponents (^), and parentheses for grouping.

Q2: Can I use nested parentheses?
A: Yes, the calculator handles nested parentheses correctly.

Q3: What's the precedence between * and /?
A: Multiplication and division have equal precedence and are evaluated left to right.

Q4: Can I use decimals in my numbers?
A: Yes, decimal numbers are fully supported.

Q5: What happens if I enter an invalid expression?
A: The calculator will display an error message explaining the issue.
