Do numbers have a somewhat inherent gender to you? They do to me. It is somewhat tied to them being even/odd with a bit of variation.
0 – Neutral
1 - Neutral
2 - Male
3 - Female
4 - Very Male
5 - Female
6 - Female
7 - Neutral
8 - Male
9 - Neutral
10 - Male
From there, most of the rest of the numbers flow naturally. So 44 is definitely male, along with 48. 33 is very feminine, along with 35. All prime numbers are female (with exception of 2 which is male and 7 which can go either way). Once above 100, they start to lose the effect.
I think this may have developed when I was a small child and learning arithmetic. Numbers that were particularly “easy” to deal with were male (because boys are way better than girls, duh!). Girls were hard to deal with, difficult.
Also, rounded numbers also tend to be more feminine (6, 5, and 3).
There are always exceptions. Although 71 is prime, (and therefore mostly female) it is a very sharp anglely number, so it does have its masculine tendencies.
I know I am not the only one that is like this….
