Copilot knows to use the tool for multiplication. Granted you can get into discussions where Copilot shows its bravado. If you ask it if it can help you make a nuclear weapon it will say "I can't" because it's been told to say so, not because it has no freakin' idea how to find you some people in Kazakhstan who have 50kg of highly enriched uranium.

Ask it if it can put a list of US states in some order it hasn't seen before it will tell you that it can, ask it what the probability that it gets it right it will say "very high". Then it will spit them back at you in the wrong order, maybe even one of the states appears twice. If you point it out it will apologize and admit that it didn't do the task successfully.

On the other hand, sometimes I tell it something wrong and it will point out my mistakes. I was testing out its ability to solve problems around transitive closure, gave it a wrong example, and it said I was wrong and it was right.
