So you'd think the first number ever invented would be the number 1, but it was actually 2. Because people didn't really need a number system until they had more than one thing to keep track of. Point being that not all numbers were invented at the same time. The first set of numbers came together as 1-9. Notice they had no 10, because they hadn't invented 0.

You never realize till you stop and think about it, but 0 is a really important number. It creates almost every prefix. And the concept of nothing is fairly interesting. How peculiar it really is. For nothing fits into everything. It carries entire equations in higher math.

In simple operations like + or - zero seems powerless. Yet in higher operations it holds all the power. All this meaning, I really like 0. Because zero is humble, it quite literally is nothing but shapes the world by being nothing. So it almost looks like to be compatible with everything you need to be nothing.
