<Nova> I have two beans in this pile. <Nova> I have one bean in this pile. <Nova> If I move this bean over to the pile with these beans, I now have no beans! <CTrombley> Now you have three beans. You can take all the beans out! <Puffin> one bean isn't a pile :V <CTrombley> Why? Because you can take beans out in groups of threes. <Nova> Sure I do. It's a pile, with one bean in it. <Nova> It's also got other stuff, which is why it's a pile. <Nova> Mainly sugar cubes, I believe. <Nova> But we were counting beans, not sugar cubes. <CTrombley> Thus if you have 7 beans, you have to leave 1. That is, 7=1 (mod 3). <Nova> No, I have seven beans. <CTrombley> You can take beans out in groups of threes, and you do. So there is one bean left,. <Nova> Why would I do that? Then I barely have any beans. <CTrombley> You do it because we are simulating modular arithmatic with beans and you want the simulation to work out. <Nova> I thought I just wanted beans.
