What Is an Expression Calculator?
An Expression Calculator is a digital tool that evaluates mathematical expressions written in standard arithmetic format.
It can solve:
- Addition (+)
- Subtraction (−)
- Multiplication (×)
- Division (÷)
- Parentheses ( ) for order of operations
It follows mathematical rules (BODMAS/PEMDAS) to ensure accurate results.
For example:
Expression:(10 + 5) * 2 - 8 / 2
Step-by-step logic:
- Solve brackets first → (10 + 5) = 15
- Multiply → 15 × 2 = 30
- Division → 8 ÷ 2 = 4
- Final result → 30 − 4 = 26
Final Answer: 26
