How to use this calculator
- Enter arithmetic expression.
- Select Calculate to see the answer and its breakdown.
- Keep a scenario, change an input and compare the results.
Use consistent units and check the assumptions below before applying the result.
How basic is calculated
Multiplication and division are evaluated before addition and subtraction; parentheses override precedence. Unary signs and decimal literals are supported. For (18 + 6) / 3 − 2, parentheses give 24, division gives 8, and the result is 6.
Evaluate parenthesized arithmetic with multiplication/division before addition/subtraction.For (18 + 6) / 3 − 2, parentheses give 24, division gives 8, and the result is 6.
Assumptions & useful context
The result depends on the values you enter and the method described above. Displayed numbers may be rounded; calculations use the unrounded values. Check that this model matches your situation before relying on it.
Frequently asked questions
Can I use powers or functions?
This basic mode supports only arithmetic operators and parentheses.
Is my expression executed as code?
No; a restricted arithmetic parser reads only numeric tokens and operators.
