..with how to use basic arithmetic options in a case state statement and then loop them with say, a "while" loop? Please be gentle as I am definitely a newbie.

Example: I need a very simple option "case statement" for these all together.

Code:

sum=$((num1 + num2))
diff=$((num1 - num2))
prod=$((num1 *\ num2))
quot=$((num1 / num2))

and then "while" looped.

thanks a bunch,

joe.
