Frage 27

What is the value of |0|?

  1. 0Richtige Antwort
  2. 1
  3. Undefined, because zero carries no sign.
  4. Either 0 or -0, depending on the context.

Erklärung

Zero stands at the point from which distance is measured, so it is no steps away from itself and the count of steps is zero. Calling the expression undefined confuses having no sign with having no value, yet the distance here is perfectly well defined.
