import math

a = input("Give me a number:")
sign = input("Give me a sign:")
b = input("Give me another number:")

result = 0

if sign == "+":
  result = int(a) + int(b)
  print("You asked for the sum")
  print(a,"plus", b, "is", result)
elif sign == "-":
  result = int(a) - int(b)
  print("You asked for the difference")
  print(a,"minus", b, "is", result)
elif sign == "*":
  result = int(a) * int(b)
  print("You asked for the product")
  print(a,"multilpied by", b, "is", result)
elif sign == "/":
  result = int(a) / int(b)
  print("You asked for the quotient")
  print(a,"divided by", b, "is", result)
elif sign == "power":
  result = math.pow(int(a),int(b))
  print("You asked for the power")
  print(a,"on the power of", b, "is", result)
else:
  print("Sorry, I don't know that sign!")
