Textbook Humor: When Numbers Get Too Big To Care

This textbook is basically saying "when your number is so massive it's stopped caring about small-time additions." Avogadro's number (10²³) is so ridiculously huge that adding 23 to it is like throwing a grain of sand into the Grand Canyon and expecting the tour guide to update the brochure.

And then there's the "very large numbers" that are so astronomically gigantic they don't even notice when you multiply them by mere billions upon billions. It's the numerical equivalent of a celebrity too famous to acknowledge your existence. These numbers have transcended mathematical anxiety - they're just out there living their best life, completely unbothered by our operations.

The footnote about "keeping track of leftover factors" is the textbook equivalent of a nervous laugh after making a dad joke at a faculty meeting.
