How to use Order of Operations Calculator
- Choose angle mode (if you use trig) first so the fields that apply to that job appear.
- Enter expression, significant digits. Leave a field blank only when the page says the value is missing.
- Read the result rows under the form. Errors appear in the status line. Nothing is uploaded.
- Rounding follows IEEE floating point in this browser unless the page says it uses integers or BigInt.

What Order of Operations Calculator is
2+3*4^2 is 2 + 3 × 16 = 50, not (2+3)×4². Unary minus binds tighter than power's right operand in this parser (standard scientific). % is remainder, not percent-of.
The formula runs in this tab. CZNull does not receive the numbers.
How this page computes
