Online Calculator

Free online calculator. Type any sum using + − × ÷, brackets, powers, percentages and square roots, and get the answer instantly.

Use + - * / ^ ( ) and %, plus sqrt(), sin(), cos(), tan(), log(), ln(), abs(), pi.

Enter your values and press Calculate.

How to use the Online calculator

Type a sum exactly as you would write it. Multiplication can be written as * or ×, division as / or ÷. You can put numbers next to brackets to multiply, e.g. 2(3 + 4) = 14.

Formula

Follows the standard order of operations: brackets, powers, multiplication and division, then addition and subtraction (BODMAS / PEMDAS). A % sign divides the number before it by 100, so 200 × 15% = 30. When you add or subtract a percentage it works like a shop calculator: 80 + 20% = 96 and 80 − 25% = 60.
