arithmatic

Hi Guys,

I am relatively new to scripting at the moment and am struggling to get the following function to work. For some reason it does not recognise the arithmatic symbol when i select option1. Any help would be greatly appreciated.

Code:

 
menu ()
{
echo "=============="
echo "Calculator"
echo "=============="
echo "1. Divide"
echo "2. Multiply and Subtract"
echo "3. Quit"
read choice
case $choice in
1) option1 ;;
2) option2 ;;
3) exit 0 ;;
*) echo "invalid option" ;;
esac
}

option1 ()
{
a=$1
b=$2
c=$(($a/$b))
echo "**********"
echo "****"$c"****"
echo "**********"
}
menu
