Formula and calculation method
Evaluate parentheses, powers, unary signs, multiplication and division, then addition and subtraction.
Supported functions: sin, cos, tan, asin, acos, atan, sqrt, abs, ln, log and exp. Angles are in radians; constants pi and e are available. Powers are right-associative.
How to use scientific calculator
- Set Expression. The example below uses 2 + 3 * (4 - 1).
- Select Calculate to update the result. Reset restores the illustrated inputs. Copy, print or download your own result if you need a record.

Factors affecting your result
Supported functions: sin, cos, tan, asin, acos, atan, sqrt, abs, ln, log and exp. Angles are in radians; constants pi and e are available. Powers are right-associative.
Changing expression changes the scenario being evaluated. Adjust one input at a time when comparing results, keep a copy of the assumptions, and compare values using the same unit and period. A precise arithmetic result does not make an uncertain assumption precise.
Frequently asked questions
How does the scientific calculator work?
Evaluate parentheses, powers, unary signs, multiplication and division, then addition and subtraction.
What inputs does Scientific Calculator need?
Enter expression. Choose values that correspond to the same situation and measurement convention.
How should I interpret the scientific calculator result?
Supported functions: sin, cos, tan, asin, acos, atan, sqrt, abs, ln, log and exp. Angles are in radians; constants pi and e are available. Powers are right-associative.
Are my scientific calculator inputs uploaded?
No. The calculation runs in this browser. Favorites, recent tool names, theme and formatting preferences may be saved locally, but calculation inputs are not sent to a calculation server or stored by this website. Shared links do not include entered values.
