"一個實數係一個有理數序列嘅極限點"

What is a real number? It depends on how you define it. For example: if you employ Cantor's method, then real numbers are equivalence classes defined on the set of all convergent sequences of rational numbers.

"實數集合係有理數集嘅封閉集(closure)"

It should be "實數集合係有理數集嘅閉包(under the usual euclidean metric space)"

"實數集嘅基數(Cardinality) 係$\aleph _{1}$ "

"連續統假說(Continuum Hypothesis)話: 實數集一一對應於數線."

The correct statement is "連續統假說(Continuum Hypothesis)話: 實數集嘅基數(Cardinality) 係$\aleph _{1}$".

"實數域有一個「亞基米得性質」(複數域就無) ......"

亞基米得性質 states that the set of natural numbers is unbounded as a subset of the set of real numbers.

Very well, would you please point the mistakes out?--Hillgentleman 2006年8月16日 (三) 02:32 (UTC)

It means the statement is wrong in mathematics completely!!! --129.67.10.1 2006年8月16日 (三) 02:17 (UTC)

What do you mean by "全錯"? Hillgentleman 2006年8月16日 (三) 01:55 (UTC)
