The User Interface

Let us describe the easy to use and intuitive user interface!

There are three number-fields. To use the tool, first pinpoint the the field that contains the unknown number, and then type in the known numbers in the remaining two number-fields!

In the figure, we have selected the first number to be unknown, and then we have typed in the numbers 1200 and 250. As a result, the tool determine that the unknown number must be 20.83 (since 20.83% of 1200 is 250).
