And one which the computer says can only be solved by brute force. I disagree.

Yesterday, I said "tomorrow" ... and the answer is a/b/c = 10/2/2025.

If I were being interviewed, I would feel much safer using the direct approach than the assume and solve approach.

Here is another example where the direct approach seems far safer…
Simplify
√(11+√120)

Mostly, in the videos I have seen, they do the simplification by assuming the form of the likely answer – eg that it will be r+s√n for some integers r,s and then solving for these integers.

There is a direct way, which seems neater to me…

That may be ok for a conversational partner, but it's a really bad thing for search and retrieval, let alone for conducting scientific analysis.
So yeah, you typed the same query I did and got a different result. That hardly a rousing endorsement of an information system.
