## Is there a free online scientific calculator?

A scientific calculator evaluates an expression with powers, roots, logarithms and trigonometry using the standard order of operations.

## Formula

Supports +, −, ×, ÷, powers (^), parentheses, sqrt, log, log10, sin, cos, tan, inverse trig, pi, e, and factorial (!).

- Supports +, −, ×, ÷, powers (^), parentheses, sqrt, log, log10, sin, cos, tan, inverse trig, pi, e, and factorial (!).
- Inputs used: Expression, Angle mode.
- Edge handling: Expression is required..

## Inputs

- Expression
- Angle mode

## Worked example: Evaluate a scientific expression

sin(30°) + √16 + log₁₀(100) = 6.5.
1. Start with Expression: sin(30) + sqrt(16) + log10(100), Angle mode: deg.
2. Apply the method: Supports +, −, ×, ÷, powers (^), parentheses, sqrt, log, log10, sin, cos, tan, inverse trig, pi, e, and factorial (!).
3. sin(30°) + √16 + log₁₀(100) = 6.5.

## Common questions

### Is there a free online scientific calculator?

A scientific calculator evaluates an expression with powers, roots, logarithms and trigonometry using the standard order of operations. Check the formula, example, and limitations on this page before using the result for a real math decision.

### Are trig inputs degrees or radians?

Choose the angle mode before evaluating. Check the formula, example, and limitations on this page before using the result for a real math decision.

### Can expressions return complex values?

No. This calculator reports finite real-number results only.

### Is this a free online calculator?

Yes. It runs in your browser with no app to install and no sign-up, and handles everyday arithmetic as well as powers, roots, logs and trigonometry.

### Is this the same as the Desmos scientific calculator?

No. This is an independent free alternative and is not affiliated with Desmos. It evaluates typed expressions but does not draw graphs.

### How do I use the Scientific Calculator?

Enter the required values for Expression, Angle mode. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.

## Limitations and assumptions

- Inputs outside the supported range are rejected rather than forced into a result.
- The result depends on the values you enter for this scientific calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
