This book presents the mathematical methods that students need when preparing for competitions, whether for the International Mathematical Olympiad (IMO) for high school students or the Putnam competition for undergraduate students.The book features six parts, each subdivided into several chapters. The six major sections address counting methods, number theory, inequalities and the theory of equations, metrical geometry, analysis, and number representations and logic. Each chapter provides detailed solutions to a series of problems as well as approximately 30 more problems; the text thus provides about 1,000 problems to be solved. In addition to its value to students preparing for competitions, this volume is a useful resource for those seeking a thorough and practical review of mathematical methods.

Very comfy
Size: X-Large, Color: White
I'm a size US Mens 14 with huge calves. Finding comfortable crew socks can be somewhat difficult.
These are extremely comfortable, very stretchy and soft. Very worth the price.

I use these exclusively for when I'm hiking, cycling and walking ( exercising )
Size: X-Large, Color: Black
5.7.2019 Update:
I have probably five packs of 3 of these socks. Can't explain it but recent pairs I've been using have lasted longer than previous two packs ( 6 socks )... So I'm going to get some more...
They are my #1 go to sock for cycling, hiking, climbing, walking ( serious, training, speed, distance )...
10.30.19:
I use these exclusively for when I'm hiking, cycling anqd walking ( exeqrcising )...
They are light, comfortable, keep feet dry, cool & comfortable... They don't shift around on feet. They stay put once put on and running, climbing or cycling shoes are put on and laced up or ratched...
I do a lot of hill climbing and also use on terrain where there's lots of long periods ( hours ) going up & hours going down...
They don't appear to be very durable, get holes in toe or holes in heels, but 3 pack is relatively inexpensive so I continue to buy them.
I do not use them for everyday casual wear because they would wear out very quickly compared to other similar sockets...
