I apologize for the long post ahead of time, however in this case it may be a necessary "evil".
We see "number" in the universe relative to the symbolic context in which we apply it, for the symbol acts as a medial point between the observer and what is being measured.
The problem occurs in the respect of the symbol itself and not just interpretation, but how it reflects "our" perception of reality and in these respects takes on a subjective context, that while objective in many circumstances, does not necessarily mirror the objective nature of reality we observe it through.
The question of "perceiving" a number, as an empirical entity (with empiricism being founded in directed movement), is a question of observing not just directed movement but universal symbols that reflect that directed movement.
Considering the linear nature of time necessitates a 1 dimensional nature, where this 1 dimensional nature effectively observes "1 as directed movement" through the line, it may be logically argued that the 1 dimensional line and "1" are both the same literally and symbolically.
We can observe this in the quantification of any temporal object is fundamentally an observation of time and numerical with number having a relativistic nature of part through part.
So if I see 1 orange, I see one direction in time.
If I see two oranges I see 2 times zones, or two directions in time, where these 2 directions in time still exist as 1 direction considering this is "one" 2 (if you understand what I am saying here).
So while time may be linear, but the line exists relative to other lines with these multiple lines observing multiple directions which may be off by just a quantum of a degree, time as linear results in time as multdirection effectively leading to a circle or sphere as "all directions" as 1. In these respects 1 takes on a dual role of constant and absolute truth through the "Monad" while observing a relativistic nature of "Monads"(atoms) that again exist through linear directions in themselves.
The nature of number alternates between a relativistic notion and one of absolute truth, where each finite reality is but an extension (or approximation) of an infinite one.
So if we quantify all of reality as "one" we are left with instead of a line, a 1d point existing as pure movement. The point exists through a point as a point and in turn can only be observed approximately as a boundless field in one respect while the connection of the points existing through eachother through lines without direction (negative dimensional).
Then you have the question of frequencies as literal numbers being alternating lines as a 1 dimensional line inverts to another.
So an angle observes 2 directions as 1 direction in the respect the angle is still directed and exists as a line in itself when viewed from far enough away. The concept of the "degree" which all angles are composed of becomes relativistic as a degree is strictly the number of geometric shapes which fit in a circle.
The foundation of the "degree" as a relation of geometric forms.
1) The circle is the universal form through which all forms exist.
x) The triangle, as three points, exists 120 times within a circle of 360 degrees with each point acting as a degree in itself. Hence as 120 times the angles which form the interior of the triangle (from the center point) form the interior of the triangle as 120 degrees.
2) The square, as four points, exists 90 times within a circle of 360 degrees with each point acting as a degree in itself. Hence as 90 times the angles which form the interior of the square exist as internal 90 degrees.
3) The pentagon, as five points, exists 72 times within a circle of 360 degrees with each point acting as a degree in itself. Hence as 72 times the angles which form the interior of the pentagon exist as internal 72 degrees.
4) The hexagon exists 60 times with an internal degree of 60.
5) The septagon exists 51.4287 times with an internal degree of the same.
6) The octagon exists 45 times with an internal degree of the same.
7) The nonagon exists 40 times with an internal degree of the same.
8) The Decagon exists 36 times with an internal degree of the same.
9) The 1 directional line exists 360 times as 1 degree with the 2 directional line existing 180 times as an observation of 180 degrees.
All degree, through angulature, exists as relation and is subject to the number of relations measured, hence the degree changes with the number of "x" shapes applied to the circle. Measurement itself is relativistic.
Yet the degree is still a line and is 1 dimensional, so what we understand of the number as a line is strictly 1 as relative units.
The frequency, in the respect it is composed of multiple alternating lines within a give framework is still projection in one direction as well, with the frequency appearing as a 1 dimensional line from a different framework. The 1 dimensional line can be observed as a quantum frequency necessitating all "1's" are composed of a finite set of numbers in themselves where "relatively speaking" a "1" may not be the same to another "1" as the first 1 may be composed of 1/1, 2/2, 3/3 to infinity and the second one may be equal to (1±x)/(1±x), (2±x)/(2±x), (3±x)/(3±x) to infinity.
Curvature equates strictly a series of approximate angles, which appear as angles relative to some limit of a different size.
So while reality observes number in a literal sense, because an localization results in a simultaneous clarity and ambiguity number takes on a possibilistic, potential and random (approximate) sense as well.
Number exists as
1) a causal (with cause being structure) and random duality.
2) actualized locality (part or atom) and potential locality.
3) limit (directed movement) and possible limit (no-limit as no directed movement).
This argument may seem a little ambiguous because of the large amount of information in one section, and may be elaborated on.
In simpler terms, "number" is perpetually moving and hence because it is perpetually moving it is constant, but relatively ambiguous at the same time when we localize any phenomenon. While we may be able to continual quantify number not all number is quantifiable relative to time.
