【論破】SNSで話題の「√x² = ±x」、数学の“定義”を無視した痛い主張を解説します

-------Summary------- There are those on social media who proudly declare that "√x² = ±x is correct," but from a mathematics perspective, the only response is "Are you serious?" This kind of hell arises because discussions proceed without a clear understanding of the meaning of equals signs or the definitions of plus and minus. They should just sink into the Landau notation swamp. Definitions are crucial!    • 【マジ？】「円周率π=2」の証明がヤバい。直感が裏切られる数学の罠      • 【衝撃】「1+1=2」の証明、出来ますか？数学徒が高校生にも分かるように解説      • 「数学なんて役に立たない」と言う君へ。数学科から愛を込めて論破します。   --Tonsuke's Profile-- Junior High School: Hardcore online gamer (20,000 hours of play) High School: Public high school with a low academic ranking (deviation score of 43), repeatedly failing English University: Graduated at the top of his class from Ritsumeikan University, Department of Mathematical Sciences Graduate School: University of Washington Graduate School (Probability Specialist) 　　　　Withdrew from school after developing depression and being diagnosed with a rare disease Currently: Active staff data scientist (manager) / business consultant 📩 For work inquiries and consultations Please feel free to contact me by email for the following requests and consultations!
