sorry buddy:
this is too general, as a question/query for me, to answer. :?

for number theory book: any school level ( grade 5-10) local book would do.

We have a study guide that specifically addresses number theory topics for both DS and PS. It's our Number Properties Strategy Guide.

I like it, but I'm biased of course. :) You can ask around and see if others have thought it was useful - my students generally tell me they think it's one of the most useful math books.
Please note: I do not use the Private Messaging system! I will not see any PMs that you send to me!!

The Manhattan Number Properties book is excellent! I found the chapters on divisibility and primes and consecutive integers the most helpful, while the other chapters were very basic. However, the book is worth the money for those two chapters alone! After going through the number properties book and the equations book for a full day my quant score went from 50th percentile to 90th percentile on the Power Prep practice tests. I highly recommend the Manhattan series!
