7 Steps to a 7 in Olympiad Algebra - Video 4: Integer Functional Equations

Be sure to follow along with my handout here: https://drive.google.com/file/d/1Wx9o... This video is the fourth of seven videos introducing the most fundamental concepts in Olympiad algebra. We continue our discussion of functional equations by analyzing a specific kind of them: integer functional equations. The integers have some incredible properties, and we'll explore how to exploit them! 0:00 - Introduction 0:30 - Integers are weird 3:55 - First demonstrative example 15:30 - The pointwise trap (most important part!) 26:20 - Second key example regarding "building up" 42:32 - Conclusion Thank you so much for watching this video, please subscribe if you would like to see more videos! #math #olympiad #algebra
