Re: Knights move?
Japan is sure part of the (far) east. It is located in the east of Eurasia; the American continent was unknown in the mainstream history for a very long time.
The original question was, how the knight's move is called in the 'east', not in Japan.
Your answer 'It is called keima (in the east)' was ...

It's called a keima. I prefer knights move.

Re: Knights move?
Just curious, do they call it a knight's move in the east? I doubt it seeing as it refers to chess and so it seems like an American go term.
In Korea, it is called 날일자행마(Narilja-haengma) or just 날일자(Narilja). It means to move as the Chinese charactor 日 (see the squares as on the go board). In the ...

How about this. Let me make a suggestion.
1. Not every single file in your computer needs to be protected or be unseen by others.
2. Suppose there is an important text file 'haha.txt' which has your bank card PIN number and email password written down.

Re: unsolvable (math) problem for a whole year, help me!
Yes I am trying to clearly define a set of a five-dimensional space.
As RBerenguel pointed out, it is currently not well defined.
I will need to think more to do this.
Perhaps some clues of the properties of set X will occur after being clearly defined.

Re: unsolvable (math) problem for a whole year, help me!
And in his example the intervall A/3<A+B<-A/2 is empty (if A is positive). I'm pretty sure, the misunderstanding lies here.
The interval is not empty, and n({(A, B)|A/3 < A+B < -A/2}) = ∞
(n(X) means number of the elements of set X)
I never stated the numbers should be positive but rather {A, B ...

Re: unsolvable (math) problem for a whole year, help me!
You are confusing yourself because you did not word your problem correctly to yourself.
Is the following implication true FOR EVERY 5-tuple (a1,a2,b1,b2,x) of real numbers?
If (a1<x<a2 if-and-only-if b1<x<b2) then (a1=b1 AND a2=b2)
To disprove it, you need to find that FOR SOME 5-tuple (a1,a2 ...

Re: unsolvable (math) problem for a whole year, help me!
Let me make things clear...
First, I am still not much familiar with math in English. What I meant by 'given' is actually 'in a situation that', so 'when' I think is a better word there.
So here is (probably) the final version of this problem.
Prove that below is not true.

My question can be summarized as,
Code: Select all
What is the error of generalizing that,
given,
{a, b, c, d, X} ⊂ {x|x is a real number}
a<X<b <=> c<X<d
then,
a=c and b=d
?

Re: unsolvable (math) problem for a whole year, help me!
The thing is, inequalities don't work like this. Even though a+b (alpha+beta) satisfy these two inequalities, it doesn't mean the extremes have to coincide. You wouldn't say:
5<d<7
2<d<9
And conclude that 5=2 and 7=9.
