The comment can't be ignored because it's sitting there flagging your
problem. Strings (in single or double quote) are strings; a sequence of
characters as used to write words. Numbers are numbers. You can't add
them together.
This over here is my friend Bob. What's 31 + 18 + Bob? The question
makes no sense, because the operation of addition isn't defined in such
a way that allows you to add numbers to human beings. You can't add
them to strings either.
