  Because a number isn’t just a representation of a size or amount - that’s called a scalar. A number can also represent a point in a space, the label of a vertex on a graph and probably some other things too.

    BTW, 0 is typically considered a scalar. As in mathematics scalar is typically defined as a field, which would require a additive identity, namely 0.

  Wouldnt it be best to think of it more as the representation of the absence of something?
