Now we can assign a new ‘bonus points’ variable that rewards the player for completing the round quicker:
bonus_points = 10000 / time_taken_seconds# Set bonus points to 1000 divided by the number of seconds it took to win the level
The next mistake is on page 4. There is a sentence fragment that makes it hard to comprehend the meaning of the lesson. Here is the link

"Let’s say we want two variables to hold parts of an a"
line1 = "123 Main Street"
city = "New York City"
I would like to continue with learning, but I want to make sure that I understand everything that is being said.
line1 = "123 Main Street"
city = "New York City"
print(line1 + ", " + city)
# Outputs "123 Main Street, New York City"
A string has been assigned to the line1 variable.
Similarly, another string has been assigned to the city variable. ", " is also a string (consisting of a comma character followed by a space character).
Since we want to concatenate/join three separate strings into a single string, so we need two + operators.
If we wanted to concatenate two strings into a single string, one + operator would be sufficient.
If we wanted to concatenate eight strings into a single string, we would need seven + operators.
As an aside, many languages have features such as string interpolation or template literals which allow for much easier creation of strings (as opposed to string concatenation involving many operators).
