Math meme: when x ∈ [1,7), duck number 7 doesn't get in
miniapeur · x · 2026-11-13
A classic programmer-style math meme: six dark ducklings numbered 1-6 stand in a row while a yellow duckling numbered 7 gazes at them, captioned "When x ∈ [1,7)" — 7 is excluded from the half-open interval. Simple, shareable geek humor.
