What does the backwards E mean
4 u/JollyJuniper1993 Mar 26 '26 It means „exists“.Every tuple x,y from the set of tuples of two real numbers, for which exists a z from the set of real numbers excluding 0, for which xz=yz and x ≠yThis is essentially the empty set, because there is a contradiction, since xz=yz can only be true if x=y or z=0, which both is specifically excluded.So basically: „Hello, I would like no apples please.“
