Challenge 3: Why the Argument-Separator Concern Doesn't Transfer to Sheets — Solution Walkthrough

Why this concern doesn't apply here:

LibreOffice Chapter 5 established that Calc's argument separator
(comma or semicolon) depends on the installation's own regional/
locale settings, which can genuinely differ between users and
machines. Sheets doesn't have this locale-dependent behaviour at
all — it uses a fixed convention regardless of the user's own
regional settings.

The separator Sheets always uses:

A comma. Every function call in Sheets — =SUM(A1,A2,A3),
=IF(B2>=50,"Pass","Fail") — separates its arguments with a comma,
matching Excel's own default directly, with no locale-based variation
to check or worry about the way Calc requires.

WHY THIS WORKS AS AN ANSWER
------------------------------
This directly tests whether the colleague's LibreOffice-specific
concern was correctly recognised as NOT transferring to Sheets — the
underlying worry (formulas failing due to an unexpected separator
character) is a genuine, real issue in Calc specifically, but Sheets
sidesteps it entirely by never varying its separator in the first
place, exactly as this chapter's own opening section stated.
