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.

Exceeds performance expectations of OEM fluids
Size: 5 Quart Jug
You know I didn't think it would work as well I've heard all these horror stories but you know what this works better than the factory CVT fluid this stuff is great this is amazing be very careful to get your levels correct that goes without saying with any transmission but once you do that this fluid is amazing I have a better performance than when I had the new transmission I serve my CvT 35 to 40,000 miles I'm using it in a 2018 Mitsubishi outlander base model and I'm also running Yokohama geolander 015s on it. If you worry about tires for you Mitsubishi or any vehicle. I'm going to say you'll call when you lander whether it's a car or crossover or an SUV this tire is amazing it's best all around tire and your rain traction is phenomenal

Good Stuff!! All low speed shudder is gone.
Size: 5 Quart Jug
I have a 2020 Nissan Altima SL 2.5l and Nissan is VERY specific about using ONLY NS3 transmission fluid. There are only a couple NS3 transmission fluid manufacturers...Nissan NS3 (Manufactured by Idemitsu), Idemitsu (a little cheaper than Nissan dealer), Triax, and Mannol (works good too).
Seeing as Nissan is still using Jatco CVT transmissions which are known to be very troublesome, and very expensive to replace I wouldn't try any of the so-called "universal" transmission fluids just to save $50 and end up replacing a $6000 transmission.
The Triax fluid seems to work very good in my car. I don't feel the shutter that I normally feel when driving slow and need to accelerate. The shudder is completely gone and operating smooth.
The old fluid had 50k miles and it was very dirty but didn't smell burnt.
I ended up doing 2 - 3 1/2 quart changes with 200 miles between the first and second change.
I plan on doing another 3.5/4 quart change every 15k miles since there is no way to completely drain the 7.4 quarts of transmission fluid. The first change, only 3.5 quarts drained from the pan.

Quality fluid for half cost in Mini CVT.
Size: 5 Quart Jug
Used in the cvt transmission in my 06 mini cooper. The fluid requirements recommended by BMW are met with this fluid. Fluid improved shifting and performance at half the cost of traditional BMW OEM fluid.

This CVT Fluid worked perfectly in a 2018 Chevrolet Spark.
Size: 5 Quart Jug
This fluid is fantastic. I bought a 2018 Chevrolet Spark with 30K miles and had a bad transmission shudder. Drained the transmission, cleaned-out the pan, and replaced the filters. Old fluid was black and this is a clear green. I loved the jug as it had a pop-up spout that was small and easy to pour, and the jug has a side handle. Transmission works great and the shudder is gone. I plan to change the filters and fluid again after 1K miles. This fluid is well worth the money!
