Non-complaining thread

The group Z contains all positive integers
Z={x ∣ x ∈ Z ∧ x > 0}.
The partial order relation R is defined as follows:
R: Z <-> Z, xRy, when x - 3y is an even number that is not negative
Explain why the relation R does not have a minimal element?

Just because (x-3y) is positive doesn't mean that x and y have to be, too.

[veris leta facies]

Nope. For a relation to have a minimal element, there must be y that has no predecessor. Is there always some x in <x,y> ∈ R? Yes. May it be: x = 3y + 2. Thus: x - 3y = 3y + 2 - 3y = 2
x - 3y is positive and even.

(why the fuck am I even explaining this here??)

No idea. I have no clue what you are even talking about. For all I know you might just make all this shit up.

Statistics is the Young Sheldon of mathmetics.

[Kugelfisch]

Sounds about right.

[VoiceOfReasonPast]

It's mathemagic.

Donald Duck already knew it.

The math doesn't add up. I mean, 6 million? Seriously?

Bought a E25 Sole elliptical machine, pretty excited because fuck the gyms I'll just make my own.
