This book contains 320 unconventional problems in algebra, arithmetic, elementary number theory, and trigonometry. Most of the problems first appeared in competitive examinations sponsored by the School Mathematical Society of the Moscow State University and the Mathematical Olympiads held in Moscow. Although most of the problems presuppose only high school mathematics, they are not easy; some are of uncommon difficulty and will challenge the ingenuity of any research mathematician. Nevertheless, many are well within the reach of motivated high school students and even advanced seventh and eighth graders.The problems are grouped into twelve separate sections. Among these are: the divisibility of integers, equations having integer solutions, evaluating sums and products, miscellaneous algebraic problems, the algebra of polynomials, complex numbers, problems of number theory, distinctive inequalities, difference sequences and sums, and more.
Complete solutions to all problems are given; in many cases, alternate solutions are detailed from different points of view. Solutions to more advanced problems are given in considerable detail. Moreover, when advanced concepts are employed, they are discussed in the section preceding the problems. Useful in a variety of ways in high school and college curriculums, this challenging volume will be of particular interest to teachers dealing with gifted and advanced classes.

So versatile! Perfect solution for dividing a room.
Size: 4 Panel-88'', Color: Grey, Size: 4 Panel-88'', Color: Grey
Perfect solution for my space. My office has to double as the hangout room for the kids and I wanted something that would block off my computer so it is left alone. This space allows me to close off my computer as much or as little as I want. It is lightweight yet has sturdy feet. This is important so that if it gets bumped it won’t topple over. The price was great and the build time wasn’t too bad! I would recommend two people for set up. I went with the grey panels and I think I’ll end up hanging some twinkle lights at some point. Great purchase!

4/5 Stars
Size: 4 Panel-88'', Color: Black
Very tall and easy to set up, the only thing I will say is that they do have large gaps in between, so you won't have 100% privacy unless you add a curtain in the back. Other than that, they are easy to fold, sturdy, and esy to assemble. The gaps are an easy fix so I would say they are worth it.

Great product and worth the money.
Size: 4 Panel-88'', Color: Black
Portable and stable. Perfect size and gives me the privacy I need when working from home. Stability is great as long as you place the stands correctly it won't wobble. I love it.

Attractive
Size: 4 Panel-88'', Color: Grey
The assembled product is just as described. The screens look great! I am using them to hide the cluttered shelving in my garage. The area now looks quite neat Something I must say, though, is that the assembly was extremely difficult. I had to use a silicone spray and some pounding to get the A and B poles to fit together. Also, it required a great deal of strength to stretch and hold the fabric panels so that the bars inserted in each hem lines up with the screws inserted in A/B poles. I strongly recommend having a partner to help with the assembly.
