[Tutor] Re: New to Python and Linux

[林培恒]

Hi Armand, I suggest you learn Linux command line first. It is the 
basic skill in Linux world, like double-click in Windows. If you know how to 
run a program in Windows with double-click, you will understand how to run most 
program in Windows. If you know how to run a program with command line, you 
will understand how to run most program in Linux. Linux command line may be 
some more difficult than double-click, but it is worthy. You can learn Linux 
command line from here:

Re: [Tutor] largest and smallest numbers (Linpeiheng)

My math is rusty. Is there a concept of greater than 
or largest in complex numbers on different axis? Which
is larger, 4+2i or 2+4i?

In fact, complex numbers can not compare directly. People always compare 
complex numbers with their 'model'. For example, sqrt(a**2 + b**2) is the 
'model' of a+bi.
