    i dropped out in 7th grade due to bullying and undiagnosed mental disabilities, despite being a “gifted” student. i always loved math but as the years went on, i felt more and more hopeless about getting back on track. i’ve been going through these videos and taking notes, exercising my brain and understanding things i could never get the hang of then. i just want to say thank you. my love for learning is so strong and this has given me proof that it’s never too late. this means very much to me

    It's known (largely, I hope) that in order to be really good at something you should master the basis of it. The fact that you start from the very basic without going into too much detail (for which there are other valuable resources, I can think of one, at least!l) is really appreciated. This way you can make sure that you don't have math gaps not only practically but conceptually. *Thanks a lot* again!

    WoW I can't believe I haven't find you earlier! I always had a scientific mind, but I was born in a non English speaking country. Even though I studied English, higher level maths and other science was still pretty hard to understand, therefore I had to learn everything from basics again in English. If I've found this series earlier, it would have saved me so much time and headache! Thank you very much for your work, it's still useful and I'm sure I am not the only one who appreciate it! 😃

    As much as I'm generally against rote memorization instead of remembering the easily memorable things and relying on logic to get to the result (until I do it frequently enough that it's worth memorizing directly), I cannot overstate how helpful it was to get the table up to 10x10 drilled into me (actually 12x12, but past 10 is far less fundamentally useful). Knowing how to get the answer is the most important part, but this specific table is used so frequently that it's incredibly worth having the answer be instant, and that also opens the door to doing less trivial mental arithmetic with more convenience than pulling out a phone.

    Whenever I do mental math I doubt myself so I repeat the operation which develops into a phenomenon of jamais vus and I end up having to build a proof, and invent mathematics for every homework problem.

      Unlike dejavú which is widely understood and Presque vu which can easily be translated Jamais Vu is not vernacular English in any social circles i have encountered in the US. I felt French was necessary to describe the way that the more I repeat a mathematical operation the more meaningless it becomes. Just like someone can repeat the word “for” and after a number of times cause it to cease having any meaning and be incapable of understanding it until they think about something else for a while.

    I'm first gonna admit I feel like the biggest nerd ever, but something about how you introduced math, and how we as humans have been collectively trying to use it to abstract the world and how many didn't get it(like me I'm here to learn calculus but from the start bc my education was very lacking on math, even tho I have managed to understand much of it by brute force), or got frustrated with it in the past, but regardless manage to keep solving the world, brings tears to my eyes(literally) bc now I feel I can finally understand, idk was a bit touching like, feeling I can be part of it somehow?
    That out of the way I think you explain exactly like I needed it to be explained with grounding on the real world. I come from the first video on the calculus playlist and it just blew my mind open, I need to see this whole series now...

    Math is so hard to explain in more sensible way or logical way of teaching but it helps a lot when you hear full detail, pause, write abit of what you learned, and then continue so on and so forth😌 sometimes there are some people needs a little bit time to pause and absorb the information to catch up if you're one of them then don't be shy to pause the video and just take your time

    I comprehend commutativity in math as driving to town. If you commute then you will experience a drive-by, thereby numbers that are commutative change order without problem.
    And associative operations are like friends giving a hug. If you have two associative numbers that means they have no problem beeing in a (😊😊) during that operation.
    Hope I got that right 😅
