Turing Calculator

-----------------------------------

What is it you are trying to achieve?
I am trying to add exponents into my calculator

What is the problem you are having?
i do not know how to do it.

Describe what you have tried to solve this problem
i tried creating a variable and running it through some loops but that did not work

Post any relevant code (You may choose to attach the file instead of posting the code if it is too long)
var num, num2 : real := 0
var symbol : string
var sum : int := 0

drawfillbox (100, 350, 520, 420, black)



locate (1, 17)
put "W A J I H' S  T U R I N G   C A L C U L A T O R" ..

locate (3, 30)
put "F-U-N-C-T-I-O-N-S :" ..

locate (5, 2)
put " MULTIPLICATION"

locate (5, 25)
put " DIVISION"

locate (5, 44)
put " ADDITION"

locate (5, 62)
put " SUBTRACTION" ..
put ""
put ""
put ""

loop
    put "Please enter your first number : " ..
    get num
    put ""

    put "Please enter your second number: " ..
    get num2
    put ""

    put "Please enter your symbol. The symbol can only be (*) , (/), (+), or (-) "
    get symbol
    put ""

    if symbol = "*" then
        put "You have selected to input the multiplication symbol"
        put ""
        put "Your two numbers will now be multiplied"
        put ""
        put "Your new answer is now : ", num * num2
        put ""
        sum := sum + 1
    end if

    if symbol = "/" then
        put "You have selected to input the division symbol"
        put ""
        put "Your two numbers will now be divided"
        put ""
        put "Your new answer is now : ", num / num2
        put ""
        sum := sum + 1
    end if

    if symbol = "+" then
        put "You have selected to input the addition symbol"
        put ""
        put "Your two numbers will now be added"
        put ""
        put "Your new answer is now : ", num + num2
        put ""
        sum := sum + 1
    end if

    if symbol = "-" then
        put "You have selected to input the subtraction symbol"
        put ""
        put "Your two numbers will now be subtracted"
        put ""
        put "Your new answer is now : ", num - num2
        put ""
        sum := sum + 1
    end if


    if sum = 1 then
        put "You have 4 answers remaining."
        put ""
    elsif sum = 2 then
        put "You have 3 answers remaining."
        put ""
    elsif sum = 3 then
        put "You have 2 answers remaining."
        put ""
    elsif sum = 4 then
        put "You have 1 answer remaining."
        put ""
    end if


    if sum = 5 then
        delay (1200)
        exit when sum = 5
    end if

    if (symbol not= "*") and (symbol not= "/") and (symbol not= "+") and (symbol not= "-") then
        cls
        put "I'm sorry, but you have entered an invalid symbol. Please try again."
        put ""
    end if



end loop



if sum = 5 then
    delay (100)
    cls
    put "You have no answers remaining." ..
    put "If you want to try this program again, please"
    put "close this window " ..
    put "and hit the run button."
    put "Otherwise, thank you for trying Wajih's Turing Calculator"
end if









Please specify what version of Turing you are using
i am using 4.1.1

Turing has a built in exponents operator (**)

ie:

2**3 = 8

-----------------------------------

no that is not what i meant. i want the user to enter a number say 24. then the user has to enter another number say 3. i want calculator to do 24 * 24 * 24. that is what i need help with.
