I don't think that you would be able to do this using shell scripts. I think you would have to run a program to do it for you.

Code:

#! /bin/bash
declare -i sum

for (( i = 1 ; i < 11 ; i++ ))
 do
  echo "Please enter number $i"
  read input
  sum="$sum + $input"
 done
echo $sum

Just paste it in a text file, give it a name and you're done. The line

Code:

#!/bin/bash

indicates it's is a bash shell script. To run it, make the file executable and run it in a terminal.

If graphics are available, you might want to check out the "zenity" package -
included with Ubuntu desktop editions by default;
see

Code:

man zenity

My version of Your solution...
file: sum

Code:

#!/bin/bash

sum="0"

for x in 1st 2nd 3rd 4th 5th 6th 7th 8th 9th 10th
do
	num=`zenity --scale --title "Enter A Number" --min-value 1 --max-value 99 \
		--text "Please, select your ${x} number." --value 50`
	sum="$(( sum + num ))"
done

zenity --info --title "Grand Total" --text "The Sum is:\n  $sum"

#End of File

to make it executable:

Code:

chmod +x /path/to/file/sum

to run it:

Code:

/path/to/file/sum

if the script is in your Working Directory, you will still have to tell
the shell the "path" to find it: a single dot meaning "THIS Directory" -
because more than likely, your current directory
is no in your global "PATH" for executables ...

Code:

./sum

Notes: shells weren't really designed with arithmetic in mind;
So...

notice the quotation in the simple assignment statement sum="0" -
becase as far as the shell is concerned the 0 character is just text.

notice the use of the "$(( ... ))" construct to force the shell to do
C-style arithmetic - and that's not a mistake inside of it - you don't have a to
reference variables with the `$` character inside the "$(( ... ))" construct
