The simple solution:

@echo off
set /P "Parameter1=Please enter first parameter: "
set /P "Parameter2=Please enter second parameter: "
java.exe -jar MathCalculations.jar "%Parameter1%" "%Parameter2%"

Enter in a command prompt window either set /? or help set for more information.

Please note that the user of the batch file can just hit ENTER or RETURN without entering anything. You may define default values for this case like

@echo off
set "Parameter1=Default Option 1"
set /P "Parameter1=Please enter first parameter: "
set "Parameter2=Default Option 2"
set /P "Parameter2=Please enter second parameter: "
java.exe -jar MathCalculations.jar "%Parameter1%" "%Parameter2%"
