This PR touches files which potentially affect the outcome of the tests of an exercise. This will cause all students' solutions to affected exercises to be re-tested.

If this PR does not affect the result of the test (or, for example, adds an edge case that is not worth rerunning all tests for), please add the following to the merge-commit message which will stops student's tests from re-running. Please copy-paste to avoid typos.

Hello @kahgoh,

This update adds a total of six tests. Four of these introduce conditions for operations involving more than two values (specifically three) for addition, multiplication, subtraction, and division. The remaining two tests cover combined operations.

Given these changes, I believe we should avoid marking this as [no important files changed] to ensure all implementations submitted by users to solve the exercise are properly retested. However, I’d appreciate your thoughts on this.
