Generally, numbers and their various uses and properties are given to mathematics. By extension, numbers are directly linked to geometry. In fact, it can be easily and clearly illustrated that numbers originate in shapes or geometries, which in turn gave rise to the arduous endeavors of mathematics to measure them and, thereby, formulate systems of mathematical computation for practical purposes such as to emulate nature for the sake of design and engineering. In short, mathematics gave rise to technology and to the rise of civilization, yet it comes from the many shapes of the natural world.
Shifting back from the concrete to the abstract, numbers are used symbolically and therefore are representations or, more accurately, are recognized as signs, principals, and symbols. A symbol is much richer, multilayered, and more complex than a mere sign, and exploring them further reveals their deeper meaning and function such as the logic of sequential order. As sophisticated as signs alone may be, they are meant to be much more simply interpreted again for practical purposes, while symbols both offer and require much deeper investigation revealing many layers of possible interpretation. This is true of the 10 Primary Numbers when understood as the symbols or archetypal principles that they represent.
