Quick everyday arithmetic.
A basic calculator performs the four core arithmetic operations — addition, subtraction, multiplication and division — plus percentage. It is designed for quick everyday sums where you do not need scientific functions.
You build a short expression and press equals; the answer is calculated using standard operator precedence so multiplication and division are handled before addition and subtraction.
Yes. 2 + 3 × 4 evaluates to 14, not 20, because multiplication is done first.
Multiply by the decimal form, for example 200 × 0.15 gives 15% of 200. For more advanced percentage work, use the dedicated percentage calculator.
Results are shown with everyday precision and long decimals are trimmed of tiny rounding noise so the display stays readable.
