You just do the same comparison that I did in the case of two and three elements. Jul15 comment Proving the Well-Ordering Property But I am proving that $S$ is well-ordered, and eventually, after having added enough elements to $S$, won't I get that $S = \mathbb{Z}^+$? So, because the two sets are equivalent, any property that one thing possess, the other thing must possess, right? In particular, $S$ possess the property that it has a minimal element; so, by the equality, $\mathbb{Z}^+$ has a minimal element. Jul15 comment Proving the Well-Ordering Property Why isn't it clear what $S$ is supposed to be? Didn't I specify that it was some subset of $\mathbb{Z}^+$, and only contained the two elements $a,m \in \mathbb{Z}^+$? Isn't that clear enough? All I am doing in my proof is continually adding more elements from the set $\mathbb{Z}^+$ into $S$. How is that any less clear than what you said about $A$ in your post?

Jul13 asked Proof About Division of Integers Jul11 comment Inductive proof of inequality $a\le ab$ for nonnegative integers I have another question, then. How does one prove that the sum of two positive integers yields a number greater than the individual numbers. Jul11 comment Inductive proof of inequality $a\le ab$ for nonnegative integers Yes, we are dealing with $\mathbb{N}$. So, my reasoning is correct? Jul11 asked Inductive proof of inequality $a\le ab$ for nonnegative integers Jul2 awarded Curious Jul2 awarded Inquisitive Jun25 comment Considering Vectors Geometrically You seem to be saying that the geometric picture follows from the way in which vector addition is defined, and the fact that $\mathbb{R}^n$ itself has a geometric interpretation?
