2.9: String Operations

The + operator works with strings, but it is not addition in the mathematical sense. Instead it performs concatenation, which means joining the strings by linking them end to end. For example:

Code \(\PageIndex{1}\) (Python):

first = 10
second = 15

first = '100'
second = '150'
print(first + second)

The output of this program is 100150.
