The main point is, that I see zero as a neutral number. What does that mean?

  • Zero isn’t even or uneven
  • Zero isn’t negative or positive
  • Zero doesn’t have numerical opposite

The meaning of the video clip: “..achievements: Zero.”
Probably zero is my greatest achievement too… 🙂

Semantically zero is none, not nothing.

In multiplication zero overrides the neutral element property of one: 1 * a, but if = 0, zero “zeroes” one. The number one doesn’t keep the identity of zero, but zero “zeroes” number 1’s neutral element property and keeps the identity of its own.

Let us examine the even and uneven property of zero from point of view of distances.

The distance of number 2 from zero is |0 – 2|= 2. 2 mod 2 = 0; 2 is even.

The distance of number 3 from zero is |0 – 3|= 3. 3 mod 2 = 1; 3 is uneven.

The distance of number 4 from zero is |0 – 4|= 4. 4 mod 2 = 0; 4 is even.

But what about our friend zero?

The distance of number zero from itself is |0 – 0| = 0. 0 mod 2 = 0, but now the meaning of zero is, that the distance doesn’t exist. There isn’t distance from zero to zero. The distance that doesn’t exist isn’t even or uneven. Therefore now zero can’t be considered even or uneven.
