More than just the ability to add, subtract, multiply, and divide, the skill of Arithmetic is the culmination of all these things combined with the ability to think freely in numerical terms. Those who are skilled in Arithmetic understand that numbers are not truly reality, but that reality cannot exist without the support of numbers. Arithmetic is considered one of the fundamental requirements for a full education; those who cannot audit their own books or determine the size of their flocks or harvest are considered less than educated by those who can. Without arithmetic, certain branches of Geometry and Natural Philosophy are impossible to learn, and those without a heavy base in Arithmetic should not bother learning Cryptology or Astronomy.

## Applications of Arithmetic

One can know all there is to know about numbers and still appear to know nothing if they can't apply their knowledge properly. Conversely, those who know little about numbers and their interactions can make a killing if they simply know how to apply their learnings. This is where the Applications of Arithmetic Skill comes into play; on its own, this is a powerful and interesting Skill, but when combined with great understanding of the identities and properties of arithmetic, it becomes much more than a mere Skill...it becomes a doorway to greater understanding of Arithmetic as a whole.

## Identities of Arithmetic

Is there such a thing as a number that never ends? Recent writings by those well versed in Identities of Arithmetic seem to point to that possibility. The mere possibility of discovering just such a number has sent shock waves through the mathematical community that were only equaled by the "discovery" of negative numbers, or numbers that cannot ever exist! Though one who studies Identities of Arithmetic will likely not earn a substantial living in terms of money, they can rest assured a long and fulfilling life of thought and discovery in this age of numerical advancements.

## Properties of Arithmetic

What makes addition addition and subtraction subtraction? Why is it that 2+2=4 and not 6? Those who are well versed in Properties of Arithmetic understand the answers better than anyone else. While knowing the answers to these questions may not seem important to most people, those who wish to develop their mathematical abilities to their fullest extent will focus on this difficult Skill; those who ignore it may revel in their ignorance for a while, but only so long as they are satisfied with a less than complete understanding of numbers.

## Theory of Arithmetic

The Theory of Arithmetic Skill is dull and fairly uninteresting, yet it is something every student of numbers must master if they wish to achieve greatness in the field of Arithmetic. How can one state that they know numbers if they do not understand the theory of addition and subtraction, of multiplication and division? More than that, however, the Theory of Arithmetic Skill gives one a sound foundation even as the thought of numbers themselves become more and more abstract. As with every Skill, a proper footing gives a person better ground to stand upon while reaching for the heights...
