The International Mathematical Olympiad (IMO) is an annual international mathematics competition held for pre-collegiate students. It is also the oldest of the international science olympiads, and competition for places is particularly fierce. This book is an amalgamation of the booklets originally produced to guide students intending to contend for placement on their country's IMO team. See also A First Step to Mathematical Olympiad Problems which was published in 2009.The material contained in this book provides an introduction to the main mathematical topics covered in the IMO, which are: Combinatorics, Geometry and Number Theory. In addition, there is a special emphasis on how to approach unseen questions in Mathematics, and model the writing of proofs. Full answers are given to all questions.Though A Second Step to Mathematical Olympiad Problems is written from the perspective of a mathematician, it is written in a way that makes it easily comprehensible to adolescents. This book is also a must-read for coaches and instructors of mathematical competitions.Shipping Notes

Works well!
Color: Black
I like having all my dish cleaning supplies handy! The drain part works well and helps the scrubbers not get mildewy.

Love that it drains into the sink!
Color: Black, Color: Black
Loving it so far! I put water in it to show how it drains into the sink. But when the water that comes off of the scrub brushes and sponges from regular usage, it does drain like it’s supposed too. There is some water that sits there but for the most part, it does drain into the sink. The little bit of water that sits there, ends up evaporating. It fits the 26 fl. Oz. Of dish soap, which is great! It holds the sponges in place. Helps to keep things around the sink clean. I had another storage container that held my stuff in but it didn’t drain into the sink so mold would form and I would have to throw stuff away. I like the fact this one has a drain, so that water doesn’t stand on the bottom and create mold after awhile. It’s easy to assemble. The quality is great! It’s easy to clean!// 8/23/25 love it so much, I bought a 2nd one for the other side of my sink! It’s also easy to clean as well.

Great sink caddy!
Color: White
This sink organizer is simple yet allows variable ways to accommodate storage. It has plenty of space to store a large bottle of dish soap in addition to sponges, brushes, and scrub pads. I choose the white design which complements my white cabinets perfectly!
