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...

NAME
echo - echo arguments to standard output SYNOPSIS
/usr/ucb/echo [-n] [argument] DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output. echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi- ronment variables. For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows: o echo your current-working-directory's full pathname o pipe the output through tr to translate the path's embedded slash-characters into space-characters o pipe that output through wc -w for a count of the names in your path. example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w" See tr(1) and wc(1) for their functionality. The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's echo() also understands a as the audible bell character; however, these commands do not have an -n option. OPTIONS
-n Do not add the NEWLINE to the output. ATTRIBUTES
