 Okay, now try to understand the boundary between natural numbers and whole numbers. Now, the reason that there is a distinct separation between natural numbers and whole numbers is when we finally began to understand the cost of zero. Okay, we'll try to define what zero was. Now consider this. One divided by ten is point one. One divided by a hundred is point zero one. Okay, take it further. One divided by thousand is point zero zero one. You get the gist, right? Let's go a little further. One divided by ten thousand is point zero zero zero one. So you've got four zeros, you've got four decimal places with the one. Okay? Now, think of a really larger number. Let's go way beyond ten thousand. One divided by point zero zero zero zero zero zero zero zero zero zero one. Continue it on. As much as you want, you're going to get point zero zero zero zero zero zero one. Now, if you take it much further than that and say one divided by infinity, the eight, this loop that you've seen many people use all over places with symbols wherever you want. Now one divided by infinity, what you're going to get is approximately equal to zero. And that's the sign for approximately, okay? So one divided by the biggest number you can think of is zero. And if you do a cross multiplication, the zero comes down, infinity goes up. One divided by zero, you're going to get anything. Now, when they actually began to comprehend what zero was, all of a sudden you had one simple equation here which was talking about infinity and nothing. So mathematics, all these philosophers coming up and talking about, you know, God and existence and, you know, nothingness and all this jazz, it all began with mathematics. Hundreds of years ago, thousands of years ago, there was no such thing as philosophers. There were all mathematicians. And this was one of the first places that us as human beings began to think about what God might mean. One divided by zero, infinity. One divided by infinity is zero. They're the polar opposites of each other, okay? So you have zero in the middle as a pivot. You've got negative infinity on one side and you've got infinity on the other side. And zero balances both out, okay? So that is the major, that is the boundary, that is the defining boundary between natural numbers, whole numbers in the real number set that we talked about earlier, okay? So super important, zero, infinity, okay? Now we talked about this, we'll go on and move on to other things. Hope that made sense.
