Try this

Code:
echo -n "Enter the data :"
while read data
do
     name=`echo $data|cut -d ' ' -f 1`
     phone=`echo $data|cut -d ' ' -f 2`
     sal1=`echo $data|cut -d ' ' -f 3`
     sal2=`echo $data|cut -d ' ' -f 4`
     echo -n "$name | $phone |"
     echo `expr $sal1 + $sal2`
echo  -n "Enter the data :"
done

Code:
declare -a array
echo "Enter the data";
read data;
count=1;
array[0]=`echo "$data"| cut -d ' ' -f 3 `;
array[1]=`echo "$data"| cut -d ' ' -f 4 `;
expr ${array[0]} + ${array[1]};

Or in a other way

Code:
echo "Enter the data :"
read data
# echo $data
x=`echo $data |awk -F " " '{print  $3 }'`
y=`echo $data |awk -F " " '{print  $4 }'`
echo "sum is `expr $x + $y`"

Code:
while printf "Enter data (ENTER to quit): " && read n p s1 s2 j; do
  [ "$n" ] || break
  echo "Sum: $((s1 + s2))"
done
