What you're showing here in your question is an example of string interpolation. Let's take a look:

number = 5500
print("Your number is: \(number)")

This will tell Swift to put the value of the variable number in that place when it prints out. So it would print out Your number is: 5500 . If we wrote it like this:

number = 5500
print("Your number is: number")

Swift would print out Your number is: number. In the second scenario, it doesn't know that you're trying to print out the value of a variable. Hope this helps! :sparkles:
