I get having it walk you through figuring out a problem with a tool: seems like a good idea and it clearly worked even better than expected. But deliberately coaxing an LLM into doing math correctly instead of a CAS because you’ve got one handy seems like moving apartments with dozens of bus trips rather than taking the bus to a truck rental place, just because you’ve already got a bus pass.
I feel like a better analogy is trying to rent a truck to move to a new apartment and after repeated failures of trucks not working they just hire a moving company for you to get you to leave
All of those tools are purpose-built for moving people. LLMs are not at all built for doing math.
