a simple calculation of the task variant according to the specified parameters is implemented.

the result of the calculation can be copied to the clipboard, if you need to send the calculation or save it in notes, etc.

an example of calculating a task option from a training manual:
Each student receives a separate task to complete the CI according to
variant of Z, which is calculated from the dependence:
Z= mod25 (NZK + PR - 2000) + 1,
where NZK is the number of the student's record book (student card);
PR is the current year the assignment was received.
For example, NZK=398, PR=2001, then
Z =mod 25 (398+2001 - 2000)+1 =mod 25 (399) + 1 =24+1=25.
So here Z=25.
