How can nothing be a number

[–] [email protected] 7 points 11 months ago (1 children)

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 an additive identity, namely 0.

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