Online Calculator

A fast, free calculator that runs entirely in your browser. It supports the four basic operations, percentages and parentheses, follows standard operator precedence (multiplication and division before addition and subtraction), and shows your recent operations below the display.

You can type directly with your keyboard: digits, + − × ÷ (or *, /), parentheses, Enter for equals, Backspace to delete and Esc to clear.

Frequently Asked Questions

Does it follow order of operations?

Yes. 2 + 3 × 4 gives 14, not 20 — multiplication and division are evaluated before addition and subtraction. Use parentheses to override: (2 + 3) × 4 = 20.

How does the percent key work?

It divides by 100: 150 × 20% equals 150 × 0.20 = 30. It also works inside larger expressions.

Can I use my keyboard?

Yes — digits, operators, parentheses, Enter (=), Backspace (delete) and Esc (clear all) are all supported.
