問下先 我見本real analysis書有construct fields of real number from rational numbers
咁construct fields of rational numbers from integers唔係都應該係同一個idea ?

Dedekind cut?
Real number係靠整個partition符合well ordering principle,archimedean property.

btw CS construct integer個方法都幾得意,{},{{}},{{{}}}...


完全唔同，construct rational number簡單好多


可唔可以講埋點解

以為你話construct real number簡單好多
其實都係define同prove佢係個field
Rational number straight forward to define
Real number is not

點解而家先黎睇real analysis

之前都有睇過 但未睇晒
同埋我ug讀辣殺mkt 無乜讀過數
依加平時得閒睇下
