## What is Scientific Calculator?

Scientific Calculator is a free online calculator from Farvixo that lets you full scientific calculator in your browser. It recalculates as you type and shows the working, so you can check how the answer was reached rather than trusting a single number. Everything is computed in your browser — your figures are never sent anywhere.

## How to use Scientific Calculator

1. **Enter your numbers** — Fill in the fields in Scientific Calculator. Everything is calculated in your browser, so your figures are never sent anywhere.
2. **See the result instantly** — Scientific Calculator recalculates as you type, with the working shown so you can check how the answer was reached.
3. **Save or share** — Copy the result or export it as a report. Free, unlimited, no sign-up.

## Use cases

- Checking a figure quoted to you before you commit to it
- Students following the method as well as the answer
- Planning a budget, loan or timeline with several scenarios side by side
- Anyone who wants a quick answer without a spreadsheet

## Tips

- Keep units consistent throughout — mixing months and years is the most common source of a wrong answer.
- Try the calculation at a slightly worse input to see how sensitive the result is before relying on it.
- The working is shown for a reason: if a figure looks surprising, read the steps before assuming it is wrong.

## Common problems

- **The result differs from another calculator** — Check the compounding basis and rounding rule. Both tools can be right under different conventions.
- **The output is blank** — A required field is empty or holds a non-numeric character — a currency symbol or thousands separator pasted along with the number.
- **The number seems far too large** — Almost always a units mismatch, such as an annual rate entered where a monthly one was expected.

## FAQ

### Does it work in degrees or radians?

Both — switch between them, and check which mode you are in before any trigonometry. A sin() answer that looks wildly wrong is almost always the wrong angle mode rather than a wrong entry.

### What functions are included?

Trigonometric and inverse trigonometric functions, natural and base-10 logarithms, exponentials, powers and roots, factorials, constants and memory. Enough for school, university and everyday engineering work.

### Does it respect order of operations?

Yes. Multiplication and division are evaluated before addition and subtraction, and brackets override both. Where you want a specific order, brackets remove all doubt — that is what they are for.

### Does it work without internet?

Yes, once the page has loaded. Everything is computed locally, so nothing is fetched and nothing about your calculations is transmitted.

### Does it keep a history of calculations?

Recent calculations stay visible during the session so you can check a step or reuse a result. Nothing is stored once you close the tab.
