[CristianAmbrosini]

Summary

• Add multiply and divide functions to calculator module
• Testing telemetry event publishing

Summary

Adds two basic calculator functions to the module: multiply() and divide(). The divide function includes guard logic to raise a ValueError on division by zero. No other changes to existing code.

Note: The PR description mentions "testing telemetry event publishing," but the actual diff shows only the two new functions with no telemetry instrumentation. Reviewers may want to clarify whether telemetry logging is expected here or handled elsewhere.

What reviewers should know

Quick scan:

• All changes are in calculator.py (lines 41–50)
• Two straightforward functions with no complex logic or dependencies
• The divide function is the only one with error handling

Minor style note:
The new functions lack type hints, while the existing process_scores() function uses them (scores: list[int], return type). Consider whether to add hints for consistency.

For telemetry reviewers:
The description mentions "testing telemetry event publishing," but no telemetry calls are present in the diff. Verify whether this is intentional, tested separately, or if instrumentation is expected here.

Real issues here that need fixing before merge. The new functions shadow existing definitions — Python takes the last binding, so the original typed versions at lines 9 and 29 are now unreachable dead code.

Logic duplication: multiply is already defined at line 29 with type annotations (a: int, b: int) -> int). In Python the last definition wins, so the typed version is now dead code — callers silently get this untyped one. Remove this definition (the one at line 29 is the right one to keep).

Logic duplication: divide is already defined at line 9 with type annotations (a: float, b: float) -> float) and identical zero-division logic. This definition shadows it, making the typed version dead code. Remove this duplicate.

Missing test coverage: Whichever divide survives has no tests for either the happy path or the zero-division guard. A regression (e.g. the guard being dropped) would go undetected. Add at least: assert divide(6, 2) == 3 and a check that divide(1, 0) raises ValueError.
