Thanks! I'd like to say !Ding, I get it--but that wouldn't quite be accurate. Suffice to say, I understand how you can use a one-to-one correspondence method to proof two collection's equality--despite not really understanding how you are generating those values (as its clearly above my math level). Therefore, from now on, I will at least not use the argument infinity!=infinity-1 when attempting to reason some conclusion. Thanks again, for taking the time to address my questions.
