Moderately complex might be inflating things. Last I read we're talking grade and middle school math.

And we're talking questions like "if all x are y, and all a are b, and some people are both a and x, ..., correct, incorrect, unable to determine based on information?"

And this is why it's not AGI. It's regurgitating synthesized examples it has seen before. It's not processing and calculating from first principles.
