Oh god, not this shit again.

[QUOTE=DarkWolf2;35292182]Oh god, not this shit again.[/QUOTE] This one guy in my calc class is hellbent on proving this. I swear, I'm going to beat his ass soon.

[QUOTE=Bradyns;35292132] 0.333... x 3 = 1/3 x 3 [/QUOTE] no

[QUOTE=Prez;35292249]This one guy in my calc class is hellbent on proving this. I swear, I'm going to beat his ass soon.[/QUOTE] He's right though.

What thi- oh, it's math.

[QUOTE=Craig Willmore;35292260]no[/QUOTE] 0.333..... is the decimal representation of the fraction (1/3). It's the same thing.

what

[QUOTE=ThisGuy0;35292284]He's right though.[/QUOTE] It's more the fact of how he goes about doing it - loudly and making a big fuss which pisses everyone off.

I'm on Spring Break. Math is not real right now.

lol. -0.

How about this .99 repeating is .99 repeating if you want it to be, and if you want to round up, its 1, simple enough?

You're forcing me to post a photo off of 4chan. [t]http://filesmelt.com/dl/0.999_1_.jpg[/t] I don't like you, Bradyns. I don't like you one bit.

Hell for all I care, .99 repeating can equal potato if you want it to.

On a side note, I like math, its too bad my teachers are trash and they only ruin my desire to do math, its so terrible. I wish I was better at math...but...I'm too bad of a student...oh well.

Math outside of school, in the weekend, no. I know some of you are math heads and actually do this for fun, but jesus christ, it only makes massive shitstorms.

[QUOTE=Prez;35292249]This one guy in my calc class is hellbent on proving this. I swear, I'm going to beat his ass soon.[/QUOTE] hellbent on [b]proving[/b] this? It's already proven.

Mathematically 0.999... is equal to 1. You could always argue that it's a case of it being infinitely close to 1 to the point were the difference is completely negligible, but unless you somehow manage to prove it, you're wrong. There is also the fact that it is equal to 1 according to mathematics at the moment and who the fuck knows how they might evolve in the future, but again you'll be the one needing to provide proof.

Isn't this common knowledge though? I thought everybody knew this. If you don't understand for some reason, here is a simple version of it: .3... = 1/3 .6... = 2/3 .9... = 3/3 and 3/3 is the same as 1.

I always thought it was obvious if the nines went on forever it might as well be the next number

[QUOTE=Prez;35292249]This one guy in my calc class is hellbent on proving this. I swear, I'm going to beat his ass soon.[/QUOTE] The good thing about maths is that when you see a proof, it's a fact.

[QUOTE=Prez;35292249]This one guy in my calc class is hellbent on proving this. I swear, I'm going to beat his ass soon.[/QUOTE] But it is true.

[QUOTE=salty peanut v2;35292581]I always thought it was obvious if the nines went on forever it might as well be the next number[/QUOTE] Might as well be the next number is different to equaling to each number. i.e. 0.999... = 1 where as 0.9999999999999999999999999 ≈ 1

So. Can anyone explain to me the articles on surreal, superreal, hyperreal, and transfinite numbers?

this is some seriously stupid shit

OH GOD THAT LISP!!!!

I'm confused why people are rating the OP dumb. Do they not like ViHart? Or do they not understand the concept and think its wrong? Or do they just think the concept is overdone and they realize that its true? I thought it was pretty cool even though I am familiar with twin representations. Explain please.

I don't like you one bit.[/QUOTE] I fucking hate this equation bullshit: [i]x = 0.999... 10x = 9.999... 10x - x = 9.999... - 0.999... (or 10x - 0.999... = 9.999 - 0.999) 9x = 9 x = 1[/i] You have to be retarded to believe that. Seriously? Do you see the flaw? One of the biggest flaws: [i]x[/i] = 0.999... ! SO WHY ARE YOU SOLVING FOR [i]x[/i]?! Ok, lets forget that big flaw.. If [i]x[/i] = 0.999 step 3 would look like (9.999... = 9.999...) ; when we subtract [i]x[/i] (0.999) it will be 9 = 9! GENIUS! The other two are true.. Specially the blue one.
