Formally, given a partially ordered set (P, ≤), an element u of P is an upper bound of a subset S of P, if s ≤ u, for all elements s of S.
WHAT THE HELL DOES THIS MEAN?? It's part of my 'scavenger hunt over the weekend'. I just have to copy this and define it so I'm not asking you guys for help but If I want to become an engineer I want to damn well understand what this means and/or the reason for it.
this too:
For some natural number n, n·n = 25.
Similarly, if Q(n) is the predicate "n is even", then
http://upload.wikimedia.org/math/1/e/1/1e1c50a5f08a7232addf68eccf891634.png
is the (false) statement

It's been far too long since I worked with set theory to be much help; therefore.....
This...is a job for Super Tangie!
Except for the natural number question: n, where n·n = 25. The answer is 5.
Natural numbers, popularly called "whole numbers", have two main purposes: they can be used for counting (http://en.wikipedia.org/wiki/Counting) ("there are 3 apples on the table"), and they can be used for ordering (http://en.wikipedia.org/wiki/Partial_order) ("this is the 3rd largest city in the country")

Okay, so I'm guessing here that your < or = to symbols are in place of "proper subset" meaning that the superset cannot equal the subset in terms of how many elements exist (the subset and superset are not exactly the same). Since the subset and superset cannot be exactly the same, this means that the upper bound of the subset S (being called u) must be larger than any other element of S (called s).
Wow, I didn't think I had it in me... I haven't had Discrete in about 4 years now... almost 5.

Okay, the diagram that you have does not state that some "even" number n results in n^2 = 25. It states the first sentence. 5 is a natural # (counting #'s is another name) so you can use 5 as that answer. The diagram actually "reads"
"For every n that is an element of (the set of real #s), Q(n) -- which I am not sure of since Q is not bolded, but could mean that n is a rational # (since Q is the set of all rationals) AND (the carat is "and" for those who don't follow) P(n, n, 25) which does result, as was said, in 5 x 5 = 25.

We all have 'catching up to do' since we only have the class twice a week soooo he makes us learn these ten or more equations per week. For the weekend I have:
Define: universal quantifiers, Do 3 of truth statements and 3 false staements, Existensial Quantifiers, Same as that, 3 T and 3 F
Define Upper Bound, 3x, least Upper Bound 3x, Lower Bound 3x Greatest Lower Bound 3x, Mathematical induction 3x, Proof by Contradiction 3x, Continous and Discrete, 3 of each and I've never seen these words before!!! Which reminds me, I'm procrastinating. Due wednesday.

I think Universal Quantifier is a statement that is always true (that is the upside down and backwards E IIRC... but don't call me on it, I haven't seen this in 5 years). If I am right about Universal, than Existential I believe is the upside down A (which means there exists one - and if it has an exclamation point, it means there exists only one... again rusty, so don't trust this part).
Upper Bound is the highest point on a graph *usually parabolic in nature - not x^2 but higher order*. Least Upper Bound is the smallest "high" point on a graph *again, parabolic - often is part of a graph that looks like squiggles in the middle, and this is the lowest of the "up" points*. Induction is a method of proving something - usually directly. Contradiction is a method of proving something by proving the opposite cannot be true - indirectly. Continuous means a graph/function does not have any breaks... there is no value of x that does not yield an f(x). Discrete... I'm drawing a blank... that's 7 or 8 years ago.
I would recommend using your text or the net to verify that what I've given here is true, but that's what IIRC from years ago. I'm kinda mystified that I remember this stuff. It seemed so hard at the time, but it's coming back so easily!
