Dr. Guo (or anyone who might have an answer),

Calculator applications on mac os do not handle operations like 11⁶³ mod 192.

It doesn't even handle 11³³ mod 192.

I do not own any windows computer.

I have already spent many hours trying to look for one that handles such computations on mac without any luck.

Could you please advise on what we can do if we cannot find a way to borrow a windows computer from someone on the exam day?

Any advice would be greatly appreciated.

Thank you,

[UPDATE]

This calculator app called SpeedCrunch handles the calculation noted above: speedcrunch.org

Would it be alright to use it on the exam date?

Please kindly let me know.
