I am just a man who has an insatiable desire for knowledge.

"For the rest, brethren, whatever is true, whatever is worthy of reverence and is honorable and seemly, whatever is just, whatever is pure, whatever is lovely and lovable, whatever is kind and winsome and gracious, if there is any virtue and excellence, if there is anything worthy of praise, think on and weigh and take account of these things [fix your minds on them]."~ Philippians 4:8

Shouldn't it be that $x=ny$? Because $x|y$ is equivalent to $y=nx$, then taking the inverse of that would be $x=ny$, which is equivalent to$y|x$

Oh, so the relation only gives the type of condition we are looking at when we take the cross product of the powerset? We don't actually look at elements in the relation?

comment Finding Upper And Lower Bounds
Oh, so the upper bound has to be greater than all of the elements in a given set; and since, like you said, c and d are not even related to each other, there is no way to tell of one is greater than the other?

comment Finding Upper And Lower Bounds
How can $e,f,h$ and $j$ be upper bounds on the set $\{a,b,c\}$? They aren't even in the set. Why can't d be an upper bound? It's above those other elements. I am having difficulty understanding the topics maximal and minimal elements, upper and lower bounds, and least upper and greatest lower bound.

I'm sorry, I forgot to attach the diagram. How could I solve this without the graph?

Oh, I see: $x \ge y$ is the same thing as $y \le x$. Also, I made an edit to my post, could you perhaps check it out for me? Thank you
