Former McDonald's Worker Does a Number Theory Proof

Number theory classic problem with Sophie Germain's identity. A few days ago I was in my storage room and found my good old McDonald's uniform with the name tag. So many memories rushed back to me after I put it on again after 10+ years. Of course, I will never forget about the teacher who once helped a hopeless kid to get his first job. Thank you, Mr. Sergio Salas. In this video, I showed if 2019^4+4^2019 is a prime number or not. Be sure to watch my previous video on "add then subtract to make things work" https://youtu.be/aE5cqOZrua8 I also introduced the Sophie Germain identity for you guys in this video. 💪 Join our channel membership (for as low as $0.99 per month) to unlock several perks, including special badges and emojis during the livestreams: https://www.youtube.com/channel/UC_SvYP0k05UKiJ_2ndB02IA/join 🏬 Shop math t-shirt & hoodies: https://teespring.com/stores/blackpenredpen 10% off with the code "TEESPRINGWELCOME10" Equipment: 👉 Expo Markers (black, red, blue): https://amzn.to/2T3ijqW 👉 The whiteboard: https://amzn.to/2R38KX7 👉 Ultimate Integrals On Your Wall: https://teespring.com/calc-2-integrals-on-wall --------------------------------------------------------------------------------------------------- bprp
