Thank you for a question and answers at Divide two into four and Divide two by four
However, can anybody explain why "dividing a pizza into 4" is different from "dividing 1 into 4"? 1 pizza and number 1 would be same one piece of object. As soon as if we add "pizza" after a or "1", It would be completely backward or flipped over. So it really does not make any sense to me. I would like to know the logic behind it. So for instance, when a teacher is explaining "1/4 as dividing 4 into 1" in math class, as soon as he add a word "pizza" as an example, it would become "dividing a pizza into 4". It would be very confusing.
I wonder why such a confusing expression / grammar was created. Who started to use such a confusing mathematical notation, assuming " mathematical notation" was created after regular expression. I want to know the history behind it.
Or maybe I should ask you this way, which expression is wrong? Both cannot be correct when sequence and positions are the same. From point of view of "into", mathematical expression seems to be wrong.But for instance, one day a mathematician started to use the expression "divide A into B" which is B/A even though general world expression was A/B when he invented the expression. Why did he do it? "Dividing A into B" made more sense to him? Most of you are brainwashed so I am pretty sure what I am saying may not make any sense to you but there must be a reason to flip over somehow. So I want to know why he flipped it over. For an example again, in C language world "=" is not equal. Equal is "==". "=" is casting a value on the right to a value on the left. So "divide A into B" had to be B/A somehow. Simply"divide A by B" was A/B but when he wanted to say "divide A ??? B" for B/A but the ??? was "into" somehow.
I still need an answer. Nobody has not answered my question yet.
I am asking you about an issue of coexistence of conflicted definition.
