Mathematical Kangaroo (also known as Kangaroo challenge, or jeu-concours Kangourou in French) is an international mathematics competition in over 77 countries. There are six levels of participation, ranging from grade 1 to grade 12.
A key observation is that the speed of the ant at a given time > is its speed relative to the rope, i.e. , plus the speed of the rope at the point where the ant is. The target-point moves with speed v {\displaystyle v} , so at time t {\displaystyle t} it is at x = c + v t {\displaystyle x=c+vt} .

For example, the Math Kangaroo USA website says, "At this time we do not subtract points for wrong answers. That may change in future." This contradicts the article. Also, the Candadian math kangaroo website states, "There is a penalty of one point for each incorrect answer. If the question is left unanswered, it is worth 0 points.
Most of the Junior Kangaroo participants are those who performed well in the JMC, however the Junior Kangaroo is open to discretionary entries for a fee. Similar to the JMC, the Junior Kangaroo is a 60 minute challenge consisting of 25 multiple-choice problems. [7] Correct answers for Questions 1-15 earn 5 marks, and for Questions 16-25 earn 6 ...
Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.
In computational number theory and computational algebra, Pollard's kangaroo algorithm (also Pollard's lambda algorithm, see Naming below) is an algorithm for solving the discrete logarithm problem. The algorithm was introduced in 1978 by the number theorist John M. Pollard , in the same paper as his better-known Pollard's rho algorithm for ...
A documentary, "Hard Problems: The Road To The World's Toughest Math Contest" was made about the United States 2006 IMO team. [101] A BBC documentary titled Beautiful Young Minds aired July 2007 about the IMO. A BBC fictional film titled X+Y released in September 2014 tells the story of an autistic boy who took part in the Olympiad.
