    “Adds a and b”?

    Sure, not useful. Thats a what, not a why.

    “Combined value needed for these outputs”

    The “why”. Useful. Shows the purpose, and explains the context it may be used in.

    Assuming the “why” is known is the mistake - and one I see from junior and mid level, I dont care what language it is, its the same. Using refactoring code as an example, without context - the why - can cause problems. What may be more efficient for one resulting value being presented can cause issues for others (let’s say precision as an example of why it could be a problem). Failing to include why something is being done is usually what introduces these problems, someone misses a different context than what they are looking at, and that belongs in a comment.

    A comment on “why” isn’t just important - for any block of code - it is, IMO, a requirement. I have and will continue to respond with “add comments as to why and resubmit”.
