minus-squarexarvoslinkfedilinkarrow-up4·3 years agoThat’s French notation iirc. More intuitive imo, but its parentheses are also mismatching.
minus-squarecarbon_datedlinkfedilinkarrow-up4·3 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}
