Write a program that asks the user for a positive 3-digit number. Then print the number in reverse mathematically

number = int(input("Enter a positive 3-digit number: "))

firstDigit = number // 100

secondDigit = (number - (firstDigit * 100))//10

lastDigit = number - ((firstDigit * 100) + (secondDigit * 10))

newNum = (lastDigit*100) + (secondDigit*10) + firstDigit

print(newNum)

I think this is what you want

is this supposed to be a question ?
