I am a teacher in one of the branch of science. So,I think I can observe something from the top of the portrait or a map and normally can make some distinction between the speakers.
But that thing whatever we say should NOT of course pass the treshold of the reality.
I clearly remember what I said, feel free please to speak more clearly.
I am again sure, this OP of topic is not unintelligent. What is more, he can understand and make distinction between what intented to be said and what sounded ftom the text.
but unfortunately this user does not have sufficient (as swansont says "fundamental") contexts of maths. Thus everything is problem for him in this regard.
anyway, perhaps some people do not want to accept the reality or cannot see it well.
a recommendation: as independent researcher and maths teacher ,here I could not really judge what the OP would like to learn or ask in the work of maths.
so, I recommend the topic to be closed.
