Free Online Calculator by CalcSolver
CalcSolver's basic calculator handles arithmetic operations — addition, subtraction, multiplication, division, percentages, and decimals — with full keyboard support. Enter numbers and operators using your keyboard, view calculation history, and copy results to clipboard instantly.
The calculator follows standard order of operations (PEMDAS/BODMAS): parentheses first, then exponents, multiplication and division left-to-right, then addition and subtraction left-to-right. 2 + 3 × 4 = 14 (not 20), because multiplication happens before addition. Use parentheses to override: (2 + 3) × 4 = 20.
Keyboard shortcuts: 0-9 for numbers, +−*/ for operators, Enter for equals, Backspace to delete last digit, Esc to clear. The history panel tracks all calculations so you can reference previous results. For scientific functions (sin, cos, log, sqrt), use CalcSolver's scientific calculator.
