Is this bash or alike? Looks like ... post in other forum (shell scripting...) and read the man page, esp. for function definition etc., array creation and assignment, variable assingnment and expansion, arithmetic evaluation and expansion. I think this does what you had in mind:
Code:
function add_subtract ()
        {
         add=$(( $1 + $2 ))
         subtract=$(($1 - $2))
         result=( $add $subtract )
         echo ${result[@]}
        }

resultArray=( $(add_subtract 10 5) )
echo "Add: " ${resultArray[0]}
echo "Subtract: " ${resultArray[1]}

P.S.: use code tags for your scripts etc...
