???? My complete productivity system: https://fokus.so Mathematics doesn't have to be complicated. In this video you will learn mathematical proofs without any prior knowledge! If you have mastered basic arithmetic, you will be able to follow this video. So that nothing is assumed, I will remind you again what prime numbers are and then guide you through the famous proof that there are infinitely many prime numbers. This proof is an ideal introductory example of a proof by contradiction. Much more interesting than, for example, proving by contradiction that the square root of 2 is irrational. I find it fascinating that you can make strong statements about the infinite structure of numbers using simple mathematical means. The mathematical proof that I present is short and easy to understand and yet contains an ingenious, creative idea. ???? Viewer survey: https://forms.gle/p8xZt3Ag2LYZGewq9 ????
