ONE: generator of all numbers, not actually considered a number; characterized reason
Book definition: Beginning, independence, innovation, leadership

So basically, our idea that the number 1 was kind of the creator of all the numbers was sort of correct, since the book states that 1 is the beginning. However, the book also counts 0 as a number, so if 0 is a number, 1 has to be a number as well and therefore considered a number. Aside from that, I believe both our interpretations and the book definition could apply to 1, since it is a single entity and therefore independent, but can also stand alone as a leader and show reason.

TWO: first female number; characterized opinion and division
Book definition: Harmony, unity, relationships, collaboration, duality, humans/human magic

I'd rather go with the book definition on this one. Division would be separating a pair of things, but if you have two entities, they would be a pair and stick together in my opinion. Two is more powerful than one in almost every instance. If you have two things and they are divided, they certainly will not be harmonious, able to work together, or accomplish anything. It just makes sense that two creates a pair rather than division and therefore is a strong number compared to our class interpretation.

THREE: first male number, combination via addition of 1 (unity) and 2 (division); characterized harmony
Book definition: Imagination, positivism, playfulness, creative expression, house elves/house elf magic, complex thought

In this instance, it kind of makes sense that our class said unity and division came together. Because the number 3 means imagination, playfulness, etc, you are combining order and chaos into creativity, in my opinion. That's how I view creativity, at least. It is also complex and not everyone has the same creativity outlook as you do.

FOUR: second female number, represented space and matter; characterized by justice and order
Book defintion: Building, formation, hard work, endurance, sober-mindedness, practicality, organization

I definitely agree with this, not because of our class definition, though. Based off the book definition of the number 2, which means unity and harmony, I'd think if you doubled that, you'd have strength and foundation as described in both interpretations. Two pairs are stronger than one and show that teamwork leads to great things, which is also characterized by hard work and perseverance.

FIVE: union of first male and female numbers; characterized by love and marriage
Book definition: Change, transition, progressive thinking, resourceful, freedom, versatility, physical world, physical touch

This one stumps me, because I think either interpretation could be accurate depending on the setting. Love and marriage between the two female and male numbers could definitely lead to a new outlook on life (positive thinking) but breaking off a marriage could also lead to freedom and new experiences in the world, so for this one, either could work depending on the context that it is being applied and what is going on in your own life.

SIX: female; characterized by creation, originality, or beginnings
Book definition: Balance, nurturing, service-oriented, responsibility/duty, family focus, domestic and work issues, stability

For this one, I think the book definition is broader and therefore probably applies better than originality or beginnings. Beginnings can mean new responsibilities and new issues to focus on, but it probably doesn't bring along stability with it. Creation however could bring on new families, friends, and work which could lead to positive new beginnings.

SEVEN: male; characterized by conflict or individuality
Book definition: Analysis, research, solitude, wisdom, spiritual focus, investigative, mysticism, magic

This one is obviously a male number since men are wiser than females. Conflict could also apply, since magic and mysticism could lead to conflicts between wizards or between forces (muggles vs. wizards).

EIGHT: female; characterized by compromise, cooperation, or balance
Book definition: Authority, finances, business, success, material wealth, self-mastery, complex thought/reasoning, fluidity, movement

Totally a female number since females are bossy authoritative figures. They are also full of complex thoughts, although I'm doubtful of the reasoning bit. Cooperation between males and females however does lead to riches, success, and good business.

NINE: male; characterized by peace, stability, or enlightenment
Book definition: Endings, tolerance, metamorphasis, cosmic, teaching, global awareness, perfection, power/strength, short-lived, immediacy

Peace and stability often means that something, usually a conflict, has ended, so I can see why these two definitions fit the number. However enlightenment also leads to tolerance and teaching, and that can be an "ending" because they bring in a new era of understanding and tolerance of one another. So perhaps it does bring peace, but it is eventually short lived just like peace is short lived in the real world.

TEN: unites 1, 2, 3, and 4, represents the idea of everything; characterized by the cosmos
Book definition: Renewal rebirth, karmic completion, mastery, beginning again with consciousness

This is sort of the same thing. I think of the Big Bang Theory when I read these two definitions, because it's kind of like a big ending/new beginning that is full of light and wisdom which brings in an age of new ideas and thoughts.
