# [Tutor] Why does my code show this?

```  Hey all,

Thought I'd try a mini-calc. Here's the code:

# This is a small calculator.
print "Mini Calculator"
print "By Nathan Pinno"
print
print "2) Subraction"
print "3) Multiplication"
print "4) Division w/o remainder"
print "5) Division with remaider"
print "6) Exponation"
print "7) Square roots"
print "8) Exit"
cal_opt = int(raw_input("What option would you like: "))
if cal_opt == "1":
X = input("First number:" )
Y = input("Second number:" )
print X, "+", Y, "= ",X + Y
cal_opt = int(raw_input("Option: "))
elif cal_opt == "2":
X = input("First number:" )
Y = input("Second number:" )
print X, "-", Y, "= ",X - Y
cal_opt = int(raw_input("Option: "))
elif cal_opt == "3":
X = input("First number:" )
Y = input("Second number:" )
print X, "*", Y, "= ",X * Y
cal_opt = int(raw_input("Option: "))
elif cal_opt == "4":
X = input("First number:" )
Y = input("Second number:" )
if Y == 0:
print "Division by zero ot allowed!"
Y = input("Second number:" )
else:
print X, "/", Y, "= ",X / Y
cal_opt = int(raw_input("Option: "))
elif cal_opt == "5":
X = input("First number:" )
Y = input("Second number:" )
if Y == 0:
print "Division by zero ot allowed!"
Y = input("Second number:" )
else:
print X, "/", Y, "= ",X / Y," R ", X % Y
cal_opt = int(raw_input("Option: "))
elif cal_opt == "6":
X = input("First number:" )
Y = input("Power:" )
print X, "**", Y, "= ",X**Y
cal_opt = int(raw_input("Option: "))
elif cal_opt == "7":
X = input("Number to find the square root of:" )
print "The square root of", X, " = ",X**0.5
cal_opt = int(raw_input("Option: "))
elif cal_opt == "8":
print "Goodbye!"
else:
print "That's not an option. Try again."
cal_opt = int(raw_input("Option: "))

Here is the screen output:

Mini Calculator
By Nathan Pinno

2) Subraction
3) Multiplication
4) Division w/o remainder
5) Division with remaider
6) Exponation
7) Square roots
8) Exit
What option would you like: 7
That's not an option. Try again.
Option: 3
3*4
12
>>>

Why does it run this way instead of going to the proper equation?

Appreciating the help so far,
Nathan Pinno
