Hello there! Have you ever seen crazy symbols while reading math proofs? First of all, I guess not a lot of people just read math proofs for fun. Anyways, today's video is all about the most commonly used proof symbols in mathematics. Writing proofs and reading proofs can be a bit difficult because it's very "up to the author's discretion" on what steps they want to include. Some people like to spell out each and every step while others like to write proofs that skip some more intuitive steps. In this video, I will talk about the different symbols and what they mean. I then go over a "translation" of a sentence written with the proof symbols.

Remember the other video I did previously on the squareroot of 2 being irrational via Proof by Contradiction. I go over that same proof but this time I write it with the math proof symbols. Some people like more english words while some people like more symbols. There's a bit of freedom when writing proofs but it can make it hard to understand and follow when there are only symbols. If you haven't seen my previous video, you can check it out here! [ Ссылка ]

Another set of symbols that you will see are certain letters that look bolded with double lines. These guys are apparently called blackboard bold, I guess that's the name of the font. These letters represent different number sets. I made a video a while back on these number sets so watch it here for a refresher! [ Ссылка ]
