I think you're completely wrong. This shows that the model learned a lot about at-a-glance math. Sure if you sit down with pen and paper you can get the answer, but few people could do these reliably in their head. But what you can do is figure the order of magnitude, and get a rough answer for the first few digits and last digits, each with their chance of being wrong. If anything, this shows that it learned math deeper than any normal computer calculator.
