Let's put it this way.
You have a cake.
Someone asks for 0.999... of the cake.
No matter how much you cut off, regardless of how small it is, you would have cut off too much.
The only way to cut off exactly the right amount would be to cut off nothing at all.
Also, if someone asks for 0.000... 1 of a cake, then no matter how much you give him you would have given him too much.
The only way to give 0.000... 1 of a cake is to give nothing at all.
Therefore 0.999... = 1 and 0.000... 1 = 0, so those of you who are saying that you have to add 0.000... 1 to 0.999... to make 1, you are really just adding 0 to 1 which does nothing.


What if I cut off 0.99999... of the cake and leave 0.0000000......1?

You're right about 0.999... = 1, but 0.000...1 is not a real number.  It is not equal to zero.

This thread will fucking THRIVE as long as retards keep posting...because angry math nerds like myself will continue to tell them they are retarded.


LOL!
You are like one of those people who considers themself a nerd but is actually stupid.
0.000... 1 is a real number. Moreso, it is a rational number.
It equals 0 because the 1 never shows up after an infinite number of 0's before it.
Also, you need to calm down and stop calling everyone who outsmarts you a retard.
It is such a commonly used word on the internet which has lost it's true meaning.
Retard means slow, and I doubt anyone in this entire thread has mental problems, or else they wouldn't know how to use jsp.

You cannot do that because to cut off 0.999... of a cake is to cut off nothing at all and to cut off 0.000... 1 of a cake is to leave nothing at all.
Either way you are not actually doing any cutting.

It is NOT a real number. When I say "not a real number", this means 0.000...1 does not belong to the set of real numbers.
The set of real numbers has a property called the least upper-bound property. This property can be used to prove that the set of positive infinitesimals is EMPTY - which means THERE AREN'T ANY. (note that this proof is trivial and easy to find; hell it's probably on wikipedia)
Now, since positive infinitesimals do not exist, we cannot have a number such as 0.000...1 (because 0.000...1 implies an infinitesimal). Q E motherFUCKING D.
But wait. I'll call you out. You said it's a rational number. Then by the definition of rational numbers, 0.000...1 would be able to be written as p/q, for some integers p and q (and q is nonzero). So what are these integers? I'll help you: they don't exist. Because this number isn't rational (nor is it real).

I won't call you retarded. I'll call you fucking stupid and uneducated. Yes I'm a nerd, and I sure as fuck know a fuckton more math than you do.

Refer to this post for my response. All you did was change the item of choice to a cake. The principal remains the same.

writing 0.000...1 doesn't mean anything
its simpliy a failure at using notation
