Over 300 challenging problems in algebra, arithmetic, elementary number theory and trigonometry, selected from Mathematical Olympiads held at Moscow University. Only high school math needed. Includes complete solutions. Features 27 black-and-white illustrations. 1962 edition.

Elementary School Math Contests contains over 500 challenging math contest problems and detailed step-by-step solutions in Number Theory, Algebra, Counting & Probability, and Geometry. The problems and solutions are accompanied with formulas, strategies, and tips.This book is written for beginning mathletes who are interested in learning advanced problem solving and critical thinking skills in preparation for elementary and middle school math competitions.

100 Math Brainteasers (Grade 7-10) is a subtle selection of one hundred arithmetic, algebra, and geometry assignments, which efficiently train the mind in math skills. It will be helpful for students attending High School and also in preparation for Mathematical competitions or Olympiads at a younger age. The assignments can equally be used in the classroom or in extracurricular activities. The fun and games are delightful, original, and solving them is even more enjoyable thanks to the funny illustrations. Most of the math problems do not require any exceptional mathematical proficiency, but above all, they challenge one’s creativity and ability to think logically. Only a few solicit the knowledge of algebraic expressions and rules of geometry.

"102 Combinatorial Problems" consists of carefully selected problems that have been used in the training and testing of the USA International Mathematical Olympiad (IMO) team. Key features: * Provides in-depth enrichment in the important areas of combinatorics by reorganizing and enhancing problem-solving tactics and strategies * Topics include: combinatorial arguments and identities, generating functions, graph theory, recursive relations, sums and products, probability, number theory, polynomials, theory of equations, complex numbers in geometry, algorithmic proofs, combinatorial and advanced geometry, functional equations and classical inequalities The book is systematically organized, gradually building combinatorial skills and techniques and broadening the student's view of mathematics. Aside from its practical use in training teachers and students engaged in mathematical competitions, it is a source of enrichment that is bound to stimulate interest in a variety of mathematical areas that are tangential to combinatorics.

Mock Exams for Math Olympians (Volume 1) - The Best Tasks from Math Olympiads The present edition aims to achieve in the math Olympians the consolidation of their mathematical skills after successfully solving a group of mock exams containing a variety of carefully selected interesting problems, as well as giving them the confidence to successfully face the exams of any math competition. This educational material will be of great help to all students who participate each year in the main mathematics competitions for elementary and middle school in the United States and abroad; and in a very special way for those who are preparing for the MOEMS contest, whose exams have inspired this edition. Furthermore, the problems included herein are very similar to those proposed in the main elementary and middle school mathematics competitions in the United States such as MOEMS, Math Alpha Contest, Noetic Math Contest, Math Kangaroo in USA, etc. This edition consists of a series of workbooks that bring together a collection of select problems by means of Mock Exams and is aimed at elementary and middle school students. Many of the problems included here have been extracted from Math Olympiads around the world and others have been inspired by them, which will allow the student to prepare by performing simulations of a math competition. Likewise, it has been considered to follow the structure and rules of the exams given in the MOEMS contests (Mathematical Olympiads for Elementary and Middle Schools) due to its great popularity in the United States and abroad. Furthermore, each Mock Exam contains 5 questions in increasing order of difficulty to be answered in a time not exceeding 30 minutes, where each correct answer is worth one point and the incorrect answer zero points. The main topics covered by the questions include: sets of numbers, arithmetic operations, math and logic puzzles, divisibility, prime numbers, GCF - LCM, fractions, statistics and probability, geometry in the plane and solids. The exams included in each volume have been divided into two categories, namely, elementary school and middle school, each of them with a total of ten Mock Exams. In this first volume the exams from 1 to 10 are included. The students may only have: pencil, eraser and sharpener. Blank sheets will not be required as the workbook has been designed so that the students can solve each question in the same workbook. No calculators, rulers, graph paper, or any other aid can be used. In addition, the students will find the answers to each question at the end of the book, so that they can verify their results obtained. Finally, the indispensable support of parents or an academic tutor is recommended so that they can guide the student in case of doubts, and the evaluation is carried out with the greatest objectivity and responsibility possible.
