Good job. Series are very convenient when we want to perform an operation on all elements in a certain way. Consider this example:

magic_numbers = pd.Series([100, 200, 300, 400, 500, 600])

The code above will divide every element of magic_numbers by 10. This means we will get

[10.0, 20.0, 30.0, 40.0, 50.0, 60.0]
Note that because of division, the elements were converted to floats (i.e. fractions - numbers with decimal points).


Add five to all elements of the respondents_age Series.

Stuck? Here's a hint!

Simply write:

respondents_age + 5
on a new line.
