Script#2 Create a script to input 2 numbers from the user. The script will then ask the user to perform a numerical calculation of addition, subtraction, multiplication, or division. Once the calculation is performed, the script will end. Note: Use the "case" or the "if/then/elseif" control structure to resolve this problem. Allow the user to input either the name of the calculation or the symbol. Also make sure you perform a check if the user types in the incorrect value. Do not use printf statement or any other statement we have not used so far in class. Add comments where necessary
