A familiar situation
Use the scientific calculator to check a homework expression such as a square root combined with powers and parentheses.
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 scientific is calculated
Enter a concise expression using +, -, *, /, ^, parentheses, sqrt(), sin(), cos(), tan(), log(), ln(), abs(), pi, or e. Trigonometric functions use radians; exponentiation binds before multiplication. For 2 * (3 + 4)^2, first add inside the parentheses to get 7, square it to get 49, then multiply by 2 to obtain 98.
Expression evaluation with operator precedence; trigonometric inputs are in radians.For 2 * (3 + 4)^2, first add inside the parentheses to get 7, square it to get 49, then multiply by 2 to obtain 98.
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
Which angle unit is used?
Radians are used for trigonometric functions.
Can it represent every decimal exactly?
No. Results use floating-point arithmetic, so very large, tiny, or repeating values may be rounded.
