But it doesn't matter. That's why I said 2 and 6 and not 2 and 5. If 2 and 5, the friend I owe the extra token to matters. If 2 and 6, even after I have honored my debt there are still enough tokens left to buy the toy.
This conversation is good evidence that ChatGPT does have a more or less average ability to reason. We’ve got humans making similar mistakes with 1 digit numbers.
Sometimes you can indeed trick some people with an obfuscated reasoning that has a cleverly hidden division by zero, but when they arrive at the conclusion that x < x, or x != x, they stop and accept that they got it wrong somewhere somehow. They don't insist that they're right and that the statement is perfectly reasonable and logical.
