Math Calculators
Scientific Calculator
A full-featured scientific calculator in your browser.
Enter the values and review the result.
Enter a mathematical expression. Supports sin, cos, tan, sqrt, log10, etc. Use "deg" for degrees.
Calculation assumptions
- *Supports arithmetic operators, common functions such as sin(), cos(), tan(), sqrt(), log10(), ln(), and constants such as pi and e.
- *Use explicit syntax such as sin(45 deg) for degrees or sin(pi / 4) for radians.
- *This is not a symbolic algebra system and does not solve equations step by step.
Enter your values and press Calculate.
Results and breakdowns will appear here after a valid calculation.
Scientific Functions Supported
Enter expressions with standard operators such as +, -, *, /, and ^. You can also use functions such as sin(), cos(), tan(), sqrt(), log10(), and ln().
Example: sin(45 deg) * sqrt(16) evaluates the sine of 45 degrees and multiplies it by 4.
- Trigonometry: sin(x), cos(x), tan(x)
- Roots and logs: sqrt(x), log10(x), ln(x)
- Constants: pi, e
Unsupported syntax and common mistakes
- Use * for multiplication, such as 2 * pi, instead of writing unclear text.
- Use deg for degree input, such as sin(30 deg), or use radians directly.
- Do not expect symbolic solving, graphing, or step-by-step algebra.
- Check parentheses carefully when nesting functions.

Accuracy and limitations
Calzivo tools are built for practical estimates, conversions, and checks. Some tools use standard formulas or simplified assumptions, and results can be affected by input accuracy, rounding, units, local rules, or changing official requirements.
Results depend on the values you enter and any simplified assumptions used by the tool. Verify important results before making decisions or submitting official information.
How to Use This Tool
Use these steps to enter the right inputs and interpret the result correctly.
Type your mathematical expression in the box.

Frequently Asked Questions
Common questions about Scientific Calculator and how to read the result.
Are angles in degrees or radians?
You can use radians directly, or add deg for degrees, such as sin(45 deg).
Does this solve equations symbolically?
No. It evaluates the expression you enter. It is not a CAS or symbolic solver.
Can I use pi and e?
Yes. Constants such as pi and e are supported by the expression evaluator.
Why did my expression fail?
The most common causes are missing parentheses, unsupported syntax, or forgetting * for multiplication.
Can I use exponents?
Yes. Use ^ for powers, such as 2^3.
Is this for exact symbolic math?
No. Results are numerical evaluations and may be rounded or formatted for display.
