1. What is Expression Evaluation?

Expression evaluation is the process of computing the value of a mathematical expression. This calculator can evaluate basic arithmetic expressions and simple algebraic expressions involving 'x'.

2. How Does the Calculator Work?

The calculator evaluates mathematical expressions by:

Where:

• Expression — Mathematical expression to evaluate (e.g., 2x + 3)
• x — Variable value (if applicable)

Explanation: The calculator substitutes any 'x' values with the provided number and evaluates the resulting arithmetic expression.

3. Importance of Expression Evaluation

Details: Evaluating mathematical expressions is fundamental in mathematics, physics, engineering, and many scientific computations.

4. Using the Calculator

Tips: Enter a valid mathematical expression. You can include basic operations (+, -, *, /) and parentheses. If your expression contains 'x', provide a value for x.

5. Frequently Asked Questions (FAQ)

Q1: What operations are supported?
A: Basic arithmetic (+, -, *, /), parentheses, and simple algebraic expressions with 'x'.

Q2: Can I use other variables besides x?
A: Currently only 'x' is supported as a variable in expressions.

Q3: What about more complex functions?
A: This calculator handles basic expressions. For advanced functions (sin, cos, log, etc.), consider specialized math software.

Q4: Is there a size limit for expressions?
A: Very long expressions may not evaluate correctly. Keep expressions reasonably simple.

Q5: How precise are the results?
A: Results are rounded to 4 decimal places for readability.
