How does it work? Have a look at the above screenshot and imagine you like to multiply some numbers
with the same multiplier, lets say 2. You start with 2*2=
Now DeskCalc remembers this multiplyer and uses it next time you need it. Any time you enter a number

see how it works.

The same works for divisions and percentage calculations. The last operation overrides the last constant and becomes the new constant. Here are some more examples:

Input   Output
2 * 2 =   4
8 =  16
3 =  6
-----------------------
8 / 2 =   4
16=   8
