Grades 11-12 Video Solutions 2018-Levels 11&12 Video Solutions 2018

Video Transcription

Video Summary

This video from the Math Kangaroo Solutions library presents solutions for levels 11 and 12 of the 2018 competition, led by Lukasz Nalewskowski. Each problem is described, followed by a guided solution process which emphasizes the importance of reading and analyzing the problem before attempting to solve it independently. Participants are encouraged to pause the video to solve the problems on their own after understanding them. <br /><br />The video begins with a calendar-based problem to identify a specific day of the week, followed by a sequence of mathematical challenges that cover numerical expressions, geometry, logical deductions, and algebra. Techniques include using factorization, logical reasoning, arithmetic calculations, and geometrical concepts to derive solutions. <br /><br />Through various mathematical scenarios, viewers learn to apply different strategies such as order of operations, understanding geometric shapes and their properties, employing symmetry and algebraic manipulation, and solving equations for unknown variables. The video aims to improve problem-solving skills related to competitions like Math Kangaroo and provides detailed explanations and methodologies to tackle complex math problems effectively.
