Free online calculator with basic and scientific functions. Add, subtract, multiply, divide, and more.

Students, shoppers, accountants, parents helping with homework, and professionals doing quick numerical work all use it. Anyone who needs reliable math without opening a separate app or reaching for a physical calculator will find it useful.
It solves routine math problems such as splitting bills, computing discounts, adjusting recipes, balancing budgets, and verifying paper math. Memory functions also let you store and recall intermediate results across multi-step calculations.
It answers questions like "What is 18% of $74.50?", "How much do four items at $12.95 each cost with tax?", and "What is 1240 divided by 8?" — any straightforward numeric question you can frame as an arithmetic expression.
