# 1 + 1 = 11 not 2

So i have my code and it doesnt add up numbers it just 1 + 1 = 11 not 2 or “3 +3 = 33” “5 + 1 = 51” and so on. How do i fix this

``````if input2 == "calculator":
print("1 = + , 2 = - , 3 = *, 4 = / ")
a = input("Type number  ")
b = input("Type another number  ")
if x == "1":
print(a + b)
elif x == "2":
print(a - b)
elif x == "3":
print(a * b)
elif x == "4":
print(a / b)
``````

other operations dont even work

``````Traceback (most recent call last):
File "C:\Users\USER\AppData\Local\atom\Computer.py", line 48, in <module>
print(a * b)
TypeError: can't multiply sequence by non-int of type 'str'

Process returned 1 (0x1)        execution time : 8.750 s
Press any key to continue . . .
``````

what you do there is string concatenation, example:

``````print("a" + "b")
``````

you do the same with `"1"` and `"2"`, to the proper maths, you need integers, not strings

Hmm i still dont quite understand…
i tried this but now it doesnt even print

``````a = int(input("Type number  "))
b = int(input("Type another number  "))
did you make changes at comparison operators as well? `1 == "1"` is false, given they are different data types
