Wouldn't it had made more sense to count in Italian?
Not that it matters, because a lot in a lot in every language.
If, and only if, a+b=c v b-c=a, but if and only if a+b=c, then b-c=-a, and a≠0, then which of the following is true when all others are false?
1) b+c-|b-c|≠a
2) b-a>c
3) a=|a|
4) b≠0
It's a really hard logic question I made.
Pretend → are bi-conditionals, and not mono.
Being given ∧, meaning or, all answer are correct, but not all at the same time. There are 4 possible sets using logic to equate for. The logic statement is ((D v E); D=True ↦ F=True) → 1; 2; 3; or 4 = True. And the rest must be false. ((D v E); D=True ↦ F=True) = P comes in handy
D is a+b=c
E is b-c=a
F is b-c=-a
If you go threw it, the only successful parse with duplicates or contradictions is so
D =T
E =F
F =T
1 =F
2 =F
3 =T
4 =F
P =F
P →1=F
P →2=F
P →3=T
P →4=F
Therefor 3 is the only answer that works
So a better question. Who cares?
