I love to show that kind of shit to AI boosters. (In case you're wondering, the numbers were chosen randomly and the answer is incorrect).
They go waaa waaa its not a calculator, and then I can point out that it got the leading 6 digits and the last digit correct, which is a lot better than it did on the "softer" parts of the test.
The funny thing is, even though I wouldn't expect it to be, it is still a lot more arithmetically sound than what ever is it that is going on with it claiming to use a code interpreter and a calculator to double check the result.
It is OK (7 out of 12 correct digits) at being a calculator and it is awesome at being a lying sack of shit.
