Basic Calculator
A quick calculator for +, −, ×, ÷, brackets and decimals. Multiplication and division are done before addition and subtraction, and brackets first of all. Results are exact where the decimal ends; otherwise they are rounded and marked ≈.
This calculator gives answers only — it does not show teaching steps. For worked, step-by-step solutions, use a specific tool such as Arithmetic or Fractions.
