And then Reudh was silly.

Jolly Ranchers and Unreal World: RPG.








That is all.

Well that exam was quite easy. But also kinda disappointing. "Prove that the product of two odd numbers is also odd". Seriously. I did that kinda thing in kindergarden.

Killing Solifuge is so fun.

In King Authur's Gold

New DF release, which makes the clothing industry actually worthwhile.

...How is it?

It's not. I think the point was to state this, then prove it. Or maybe he meant to say even.

[Darvi]

Wait what. If you multiply two (or more) odd numbers you always get an odd number. An odd number is defined as a natural number that can be divided by 2, that is, has 2 as a prime factor. A product inherits the prime factors of its factors. Ipso facto, the product of two prime numbers doesn't have 2 as a prime factor since neither factor did. Q.E. motherfucking D.

It's different from the proof I used in the exam but works too.

[Urist Imiknorris]

From thinking about it for a couple seconds:

Odd numbers are numbers that take the form of 2n+1, with n being an integer. So the product of two odd numbers is

2n₁+1 * 2n₂+1 = 4n₁n₂ + 2n₁ + 2n₂ + 1,

 which can be simplified to 2n₃+1, with

n₃=2n₁n₂ + n₁ + n₂.

EDIT:

An odd number is defined as a natural number that can be divided by 2, that is, has 2 as a prime factor.

No, those are even numbers.

[Darvi]

Yeah, that's the one I used.

[Frumple]

... what? Product, not sum. Math vocabulary

E:Thoroughly ninja'd.

I meant to say "cannot" and "has not". Aderp. Speedtyping can be a bitch.

[Simmura McCrea]

Read it as sum. Shows how well I'm doing in maths. :/
