Use a straightforward calculator for everyday addition, subtraction, multiplication, division, and supported expressions.
Basic Arithmetic and Order of Operations
This calculator is designed for everyday addition, subtraction, multiplication, and division. Enter values with the on-screen keys or supported keyboard input, then evaluate the expression. The clear-entry control removes the current entry, while the full-clear control resets the calculation.
Review longer expressions
For expressions with several operations, check the order of operations and use parentheses where needed. Results are limited by standard browser number precision; use dedicated high-precision software for financial records or scientific work requiring exact decimal arithmetic.
Example and limitations
Use parentheses to make the intended order explicit in longer expressions. Multiplication and division are evaluated before addition and subtraction, while parentheses are resolved first.
