Thanks oombera, this is what I got so far, looks about right but I'm not sure. Math is clearly not my strong point. I added 3 + 3 + 3 and devided it by 3 and got 3. I know I'm supposed to get 7. I don't understand what I'm doing wrong. It's so fustrating!! 
ksh-2.04$ cat>Average
echo " Enter 1st Number "
read num1
echo " Enter 2nd Number "
read num2
echo " Enter 3rd Number "
read num3
((total=(num1+num2+num3)/3))
echo "The Average Of The 3 Numbers Is" $total
exit
ksh-2.04$ sh Average
Enter 1st Number
3
Enter 2nd Number
3
Enter 3rd Number
3
The Average Of The 3 Numbers Is 3
