It's different because nobody is actually going to ask this silly question in good faith. It does not matter in the slightest bit to anyone whether Google can produce a correct answer to nonsense questions that nobody is ever going to actually ask with the intention of getting a correct answer. Google also can't produce correct answers to queries written in ancient undeciphered languages. Oh well.
It also seems rather unlikely that someone would search for "2+22", but not obviously any more or less unlikely than "2+2", and building a calculator into your search engine is trivially easy compared to handling natural language queries, so it's not a useful comparison.
> Whether the user meant to ask a different question is irrelevant.
Of course it's relevant. If Google can correctly determine what question the user meant to ask, then obviously Google should provide an answer that provides value to the user instead of trolling the user with nitpicking about spelling or what have you. If you ask Google for the "capitol of India" you'll get New Delhi, even though that is the "capital" of India, and arguably the "capitol" of India is actually the Chandigarh Capitol Complex, so the result is "objectively wrong".
