The Manhattan Number Properties book is good, but the advance chapters for Divisibility Primes and Evens Odds/Cons Integers/Postives and Negatives are troubling me. I just worked through the suggested problem set for Divisbility Primes and got a good amount of the PS QUestions wrong. I got all the Advanced Data Suffiency QUestions wrong.
The specific topics I struggle with are as follows:
Remainders
Divisbility and Primes
Absolute Values in the context of Number Properties.
What do you suggest I do to improve this??
ARe there any alternative books availible or any help availible? Please do not reccomend foundations type books I understand the basic chapters.
