How the Human Brain Contends With the Strangeness of Zero

Zero, which was invented late in history, is special among numbers. New studies are uncovering how the brain creates something out of nothing.

In some ways, zero is just like any other number on a number line. But a new study suggests that the mind may treat the symbol for absence differently.

Zero is a number, but zero is not a finite number. You cannot understand zero without understanding infinity because zero is infinitely small. Also, you can have positive zero, negative zero, and neutral zero. If a series of numbers approaches zero, it can do so from the positive side, shrinking towards nothing, it can do so from the negative side, and it can oscillate around zero, with one number being slightly below zero and the next slightly above.
You can't divide anything by zero, but you can divide n by x and then let x approach zero. If you have a positive zero, it will go towards positive infinity, with negative zero, it will approach negative infinity, and with a neutral zero that is neither positive or negative, you will get a kind of neutral infinity that is both positive and negative.
Zero is crazy.
