Hi, I'm having trouble understanding how to evaluate the last digits of a given extremely large number. I know it has something to do with modular math, but I'm struggling with that still. If anyone could explain how to :

Find the last let's say 2 digits of 1402^1402. It would be very appreciated, because I'm really interested in modular methods, I just keep struggling on them.

If you have any other helpful tips, I'll gladly listen, thanks :)
