Subnumerics
Another perspective/try
Functions are introduced in algebra, and used for many classes afterward, to calculus and onward.
According to this page, this is a proof of a function. There is no addition, subtraction, division, or multiplication in the proof of a function, so functions can be used in subnumerics.
Here is a new one.... You do not need numbers to prove functions work, so they can be used with subnumerics (I believe).
It is saying a function of a placeholder locater is equal to a placeholder.
...Like a function of (x) is equal to x.
I need to work on this, but it's a start, and I only had 5 minutes to think of this and write it down.
This works out in par perfectly as there can be only one x per y in a function, but many y per each x.
There can be only one ph per NV, but there can be multiple NV per ph. This fits the rules of subnumerics perfectly.
Functions can be used for subnumerics for this reason without breaking the rules of placeholders.
