Basic Calculator
A simple, free calculator for everyday arithmetic — just like a physical calculator, right in your browser.
When to use a basic calculator
For quick everyday math — adding up a grocery bill, splitting an expense, or checking simple arithmetic — a basic calculator is faster than doing it by hand. For more advanced math involving trigonometry, logarithms, or exponents, try the Scientific Calculator instead.
Frequently asked questions
Does this calculator save my history?
No — calculations happen entirely in your browser and nothing is stored or sent anywhere. Refreshing the page resets it.
What's the difference between this and the Scientific Calculator?
This one covers the four basic operations (add, subtract, multiply, divide) with a familiar button layout. The Scientific Calculator adds trigonometry, logarithms, powers, and roots via typed expressions.
