A=B does not mean B=A
I agree that the person you're replying to didn't actually refute OOPs claim, but...uhh...I think A=B does mean that B=A
It should say A=>B and B=>A of course.
I guess I should have included an /s
I wasn't trying to refute anything as much as I was shitposting
I expect you meant that A => B doesn't imply B => A
The commutative property of equality is established. You might be thinking of conditionality.
Given:
If A then B, and
B is TRUE
we cannot say for certain A is true
