Pythagoras believed odd numbers were inherently masculine and even numbers were feminine

A closer look

Assigning genders to abstract mathematical concepts is peak ancient mystic behavior. The Pythagorean cult didn't just invent numerology; they attached bizarre emotional baggage to digits. They decided that odd numbers were masculine, strong, and divine, while even numbers were feminine, weak, and earthly. This meant that simply doing addition was essentially a deeply misogynistic mystical exercise. Good luck trying to split a restaurant bill when the number four is culturally offensive.
