AI explanation
Formula
Evaluates the expression using standard operator precedence (^ highest, then × ÷, then + −), right-associative powerWorked example
sqrt(144) + 5 × 2
| Field | Value |
|---|---|
| Expression | sqrt(144) + 5 * 2 |
| Angle unit (for trig functions) | degrees |
| Result | 22 |
Assumptions
- Expressions are evaluated with a dedicated safe parser — not with a general-purpose code evaluator — so only arithmetic, the listed functions, and the constants pi/e are supported.
- Trigonometric functions use the angle unit you select (degrees or radians).
Frequently asked questions
What functions does this calculator support?
Basic arithmetic (+, −, ×, ÷, ^ for power), parentheses, and the functions sqrt, sin, cos, tan, log (base 10), ln (natural log), and abs, plus the constants pi and e.
Does it matter whether I use degrees or radians?
Yes — for trigonometric functions (sin, cos, tan), the angle unit setting changes the result. Most everyday calculations use degrees; scientific and engineering contexts often use radians.
Why doesn't dividing by zero give a result?
Division by zero is mathematically undefined, so the calculator shows an error instead of a misleading numeric result.
