== Regarding Textbook == |
|||
As I was about to do assignment 3 which was due yesterday... |
|||
I realized that my textbook was missing several pages... |
|||
obviously I couldn't do the assignment... |
|||
and it looks like i am missing almost entire chapter 15... |
|||
I didn't buy the textbook because a friend gave me a photocopied version... |
|||
If I had known that there are pages missing, I would've bought one... |
|||
I am wondering if anyone is willing to scan some pages for me... |
|||
The pages are... pages 262-265, 286-293, 302-305... |
|||
or, atleast please type up the questions that are due next week |
|||
so I can atleast try to do the assignment... |

Thank you all!!! |

something i still unclear on ideal test..
since there are two conditons in ideal test 1. a-b in A whenever a, b in A 2.ra and ar are in A whenever a in A and r in A
i just wonder when i use the ideal test, i need to use both condtions together
or just use one of both , then i can conclude a nonempty subset of a ring R is an ideal of R
thx
I would think both need to be satisfied. Sorin.c
thx so much
now, i have a tiny question, is the Z/n equal to Z_n? are they the same thing.
because the textbook give us the symbol " Z_n", and the lecture notes give us " Z/n"
there is any difference? BY the way, i just uploaded a picture , just follow the link please:
