whats happens when you add the numbers 1 and 1 together (1+1)
11
32
2
9
Answer:
2
Explanation:
The mathematical answer would be 2. To get 11, one would simply put the 1's next to each other but there is an addition symbol. 32 is an irrational number to think of for an answer because there are no other numbers to add or multiply with the 1's to achieve 32. 9 is also irrational for the same reason.
If the following code is executed, what is the output? a = 1 b = 2. c = '3' d = (1, 2., '3') e = [4, 5., '6'] print type(b+c)
Answer:
TypeError
Explanation:
b = 2
c = '3'
- b is of type integer because it is storing an Integer.
- c is of type string, since '3' is a string.
Since they are of different types, you can't add/ concatenate them. To add them you would need to change the string ('3') to an integer to get 5. Or you would need to convert 3 into a string to get '32' or '23'.
