Every PROOF you've seen that .999... = 1 is WRONG

It's true, so why so many wrong proofs? There are many incorrect proofs that .999... = 1 on YouTube and elsewhere. In this video we see why all those proofs are wrong, and then demystify what is actually meant when a mathematician says .999... = 1 and I explain why it is actually true. Did your favorite math creator make one of these mistakes? *Title only applies before the first viewing of this video and only to people who have not studied real analysis. ― mCoding with James Murphy (mcoding.io/) References on the standard definition of decimals and repeating decimals (please read if you are confused or unsure about the standard notation): www.math.utah.edu/~bertram/courses/4030/Reals.pdf people.math.sc.edu/filaseta/gradcourses/Math785/Ma… www.ndsu.edu/pubweb/~comez/Decimal%20expansion.pdf kevincarmody.com/math/repeatingdecimals.pdf amsi.org.au/teacher_modules/pdfs/Real_numbers.pdf SUPPORT ME ⭐ --------------------------------------------------- Patreon: patreon.com/mCoding Paypal: www.paypal.com/donate/?hosted_button_id=VJY5SLZ8BJ… Other donations: mcoding.io/donate BE ACTIVE IN MY COMMUNITY 😄 --------------------------------------------------- Discord: discord.gg/Ye9yJtZQuN Github: github.com/mCodingLLC/ Reddit: www.reddit.com/r/mCoding/ Facebook: www.facebook.com/james.mcoding
