Introduction
Hello everyone, this file contain 100 problem in inequalities, generally at Pre-Olympiad level. Those problems has been collected from MathLinks.ro at the topic called ”‘Inequalities Marathon”’. I decide to make this work to be a good reference for young students who are interested in inequalities. This work provides some of the nicest problems among international Olympiads, as well as some amazing problems by the participants. Some of the problems contains more than one solution from the marathon and even outside the marathon from other sources.

The file description: I- The next page contain all the members that participate with URLs to their MathLinks.ro user-name information and also that page contain some of the real names of the participants that like to have their real names on this file. II- Then there are some pages under the title of ”‘Important Definitions”’, this page contain some important definition that you may see them in the problems so if you don’t know one of those definitions you can look at it there. III- Then the problems section comes each problem with its solution(s). A- The problem format: ”‘Problem No. ‘Author’ (Proposer):”’ B- The solution format: ”‘Solution No. (Propser):”’ (Note that the proposer of the solution is not necessary the one who make this solution)

I would like to all the participants of this marathon for making this work, also I would like to give a special thank to Endrit Fejzullahu and Popa Alexandru for their contributing making this file.

If you have another solution to any of those problem or a suggestion or even if you find any mistake of any type on this file please PM me at my MathLinks.ro user or e-mail me at hasan4444@gawab.com.
