minus-square@carbon_datedlink3•3 years agoI never saw that notation. I learned to write ]a, b] instead.
minus-square@xarvoslink4•3 years agoThat’s French notation iirc. More intuitive imo, but its parentheses are also mismatching.
minus-square@carbon_datedlink4•3 years agoYeah, they do mismatch. I just mentioned it because I was unfamiliar with the notation in the image. You could also write {x ∊ ℝ : x > a ⋀ x ≤ b} or [a, b]\{a}
