How the Evaluating Calculator Works

The calculator applies the order of operations, also known as PEMDAS:

1. Parentheses
2. Exponents
3. Multiplication
4. Division
5. Addition
6. Subtraction

This rule ensures that mathematical expressions are solved correctly and consistently.

For example:

Expression:

8 + 4 × 3

According to order of operations:

4 × 3 = 12
8 + 12 = 20

Final Answer: 20

Our Evaluating Calculator automatically applies these rules to produce the correct result.
