It's Time To Move!

Oh, my god! It's Math 2.0 Day! Looks like an infinite number of numerals and characters today! Hi there. I'm the manager of Hilbert’s Infinity Hotel, it's a hotel with an infinite number of rooms and guests.

Why so many on Math 2.0 Day? ‘Cause it actually means “advanced math”, so all numbers would like to take a vacation, and since here is the most famous vacation spot, so more will come here. This day was founded by Math 2.0 Interest Group, in 2009, and since then, every year, I would have to deal with lots of customers.

On normal days and nights, this hotel invented by David Hilbert would only have about one guest per night, when that happens, I just call the guest to move to the next room, which means everyone should move N+1. But when an infinite number of guests arrive, like on today, then all guests would have to move to 2N, with all the odd number rooms empty, new guests can move in. My worst fears, they are coming! Anyway, this is just the beginning of infinity, so beware, don't get stuck in rooms like one-half.
