Is 1 more that one number?

[caz105]

I just started A level further maths (college) and we were looking at special numbers Pi, Phi route 2 and we started to do number one and I found out that 1 can equal 0.99999...
Proof: 1/3= 0.333... 3*1/3= 0.99999 which is also equal to 3 divided by 3 = 1.
So what do you think?

OMG i did this in like the 7th grade >_>

check your math again
3*1/3 = 1
.333 does not equal 1/3

 

[Legion]

It's things like this which make me hate science and maths.

 

[caz105]

check your math again
3*1/3 = 1
.333 does not equal 1/3

I'm sorry that my PC doesn't have a recurring symbol. The ... implies it keeps going for infinity.

Ugh, I thought I was doing high math. I think 0.333... does not equal 1/3. 0.333... should
equal 33333.../10000... Therefore 1/3 cant equal 0.333... because 1/3 does not equal 333333.../100000....
1/3 cannot be put in decimal form.
Im probably wrong, but why does 1/3 equal 0.33333.... when 0.33333.... equals 33333.../1000...
and 1/3 does not equal 333333...../100000....

This, except I'm starting A-Levels, am nearly 17. We've even had this on the Escapist before, so this is a repeat thread.

Problem is that by that logic every number is more than one number. Integers themselves are artificial because no units are exactly alike.

You wait until you get onto simultaneous differential equations to state the parabola of an infinite function. Fun.

You know, I think I remember seeing a thread about this waaaaaaaay back last year when I first joined... do a search, see if you can dig it up. I remember the discussions getting a bit rediculously heated XD

[Starnerf]

Not this topic again. Didn't the last one get several hundred posts of people arguing back forth?

 

[silasbufu]

college? wow..your teachers must be bored. anyway..the answer is blue

Sorry, my brains blank out at the sight of maths...

Aren't those still part of the rational numbers? Irrational numbers being things like 5i
i² = -1

1/3=/=.33333333333333333333333333.....
only approximately.
repeating decials are approximate.

oh, this.

my friends refuse to accept that this is true, despite me proving it to them. their denial is rather childish.
