What can you use it for?
Use it when solving an exercise, checking a result, or working with the particular quantities shown in this form. Calculate arithmetic expressions using the on-page keypad.
How to use it
- Type a mathematical expression or use the keypad.
- Choose degrees or radians for trigonometric functions.
- Select Calculate (or Generate for random tools).
- Read the answer and any additional results below the form. Check the units and the limits of the method.
Formula and method
The parser uses standard order of operations. Powers associate to the right. A percent sign divides its preceding value by 100; it is not modulo.
Worked example
Expression: 2 + 3 × 4, using degrees for trigonometry. The result is 14 (result).
Assumptions and limits
Inputs and outputs must stay within the supported finite number range. Displayed decimal answers may be rounded.
