Using the calculator is very simple just enter the formula in the command line using the keyboard or mouse then press "=" or ENTER key, the result will appear in the result window

Examples, enter below commands and press ENTER to see the results:

- 1.2 + 3.2 =
- sin(90) + 0.2 =
- 2.0E+2 + 30.0 =
- (2.0*2.0)^3.0 =
- 2! =
- 1.2^3.2 =
- sin(90) * 0.2 =
- 1.2 / 3.2 =
- cos(60) - sin(60) =
