Sophie squinted her eyes at her parchment, not because she couldn't see what she'd written, but because she was thinking hard about what the answers might be. Finally, she put her quill to her parchment and jotted down a few ideas.

ONE: generator of all numbers, not actually considered a number; characterized reason
TWO: first female number; characterized opinion and division
THREE: first male number, combination via addition of 1 (unity) and 2 (division); characterized harmony
FOUR: second female number, represented space and matter; characterized by justice and order
FIVE: Five is a combination of two plus three, and since two is a female number and three is a male number, I think five could represent love. It sort of makes sense to me, since we weren't told that we could also combine 1 and 4 to equal 5. It's like we purposely added just the female plus male numbers. <333
TEN: Ten is a combination of ALL the numbers listed above. We were told it comes from adding combinations of 1, 2, 3, and 4, and since we also got to 5 by adding 2 and 3, I think ten means EVERYTHING. So it would equal reason (1), opinion/division (2), harmony (3), justice/order (4), and love (5).

SIX (2x3): Represents creation, new life formed after marriage.

SEVEN: Maybe seven is a combination of two and five. Two means opinion and division, while five means marriage. Maybe seven means being able to keep your individuality (uniqueness) despite becoming one with someone else. Kind of like being true to yourself.
EIGHT: I don't think we'd get too much by adding four to itself, so I think eight is a combination of three and five. Three means harmony and five means marriage, so I think eight means learning to live with the person you married (living in harmony) and getting along with them. Maybe it means you work together to have a happy life.
NINE: Maybe nine is a combination of three and six. Three means harmony and six means new life, so maybe this is the decision to have a second child. Or maybe it means a new life together as a husband, wife, and child.

She turned around to her partner and showed her what she'd come up with. "What do you think about this?" she asked, pointing to the seven, eight, and nine. Also... "I'm Sophie, by the way."
