Ha! I had not looked at it that way before.
Insofar as addition is an abstract representation of merging two collections, we are abstracting away the information that links each element of the resulting collection to the one it came from.
- aserafini 7y agoIsn’t this exactly the same for subtraction, multiplication and division?
- mannykannot 7y agoConsidering integer operators specifically: in subtraction, you partition a collection and then discard one part. Multiplication is more abstract, as one of the operands denotes the number of applications of an operator (addition), and in division, the result is a count of the number of applications of a subtraction. I'm not sure if that can be called the same as addition in this regard, but they all lead back to that case.
