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

are you back in school?

[@gabriels2395]

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!

Where are you now? Did you pursue it (tackling the basics) as much as you had hoped? If you didn't, do you regret not doing so?

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! 😃

[@sakshamgoel1957]

Professor dave you are great strating from basic, hope we will reach master level in some months

[@1gianny]

I learned all this back in elementary school, I wish I had continued with math in high school and then Uni. Here I am now, at 23, trying to learn math again, because I realised what I missed out on by hating math so much in school, yet I had very good grades...

I always label my self as dumb because I've been missing out the basics so much that when in high school I just be there in math class just to stare blankly, I know I don't hate math, but I think I do because I don't understand it. I'll learn it starts from the ground, thanks to you, your videos are blessing

[@NedTheRat]

Same here! Although I never even went to school yet so I'm just hoping I'm capable of knowing what they are talking about in college 😨

These classes help me improve my English vocabulary because my native language is Russian. I started teaching about 1 year ago, and now I can understand simple videos. thanks! ❤

[@dehondvandeburen7800]

Хаха удачи! Мой родной язык это голландский и я благодаря изучению русского языка понял что мне нравится учиться.. Я только ходил в школу до 15 лет и никогда не учил математику в школе так как ходил в школу для долбоёбов лолол так что взялся за математику и биологию и одновременно пытаюсь подучить английский немножко)) надеюсь на то что через года 3 буду знать математику на таком же уровне как русский и что я через 3 года будучи старикои (мне сейчас 33) наконец-то смогу поступить в университет

[@isidoreaerys8745]

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. Mathematics to me is very abstract. I have a semantically oriented memory which organizes ideas by meaning rather than by rote

[@doriantietz2222]

Wow I can really identify with that and this perfectly discribed how I felt all along. I have just never been able to understand and discribe this difference in approach and how it made maths hard for me even though I thought I wasn't incapable of comprehension. Cheers.

[@isidoreaerys8745]

@@doriantietz2222 why thankyou. In my writing I have always prioritized precision over humor or being widely understandable. It is validating to hear that others can identify with it.

[@isidoreaerys8745]

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.

[@MinaMyoui-l8c]

Well as the master said, without a proper understanding of the fundamentals, one would be too focused on memorization

[@shinluis]

YOU'RE SAVING MY LIFE MAN!!

[@zunaslogic4128]

Why are some people being mean in the comments? It's literally stated that it's math from scratch. We get it. You're already geniuses. You can just skip the basics if it bothers you that much smh

[@anugrahhardantiputri9006]

As foreigner all these videos from scratch just helping me to understand enough about languages they used in mathematics. That English isn't our mother language. 😅

[@Qazqi]

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.

[@Manuel-wq5fs]

Thankyou Mr. professor Dave for the class❤

[@Cherry-qs9rh]

i just came here to learn it again. since i was middle school i didnt catch up math due to my hearing loss and wont be able to hear the teacher so i cant listen it to her until after i graduate on k12, so i just came here to learn division and others so i can memorize it i have more time to study at home so im hoping i can pass the university exam in college..

[@melinaalba63]

Thank you for this! I am 24 and in uni for an engineering degree and while i live maths i have realized many times that i just dont have a feeling for it. I even start questioning why, when you have want 15 apples and each basket has 5 you have to divide 15/5 and get 3. I can do that and many other calculations but i just take so much time for it. I really hope with working through this playlist i will finally gain an actual feeling for math

[@AirmanCS]

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...

[@adeelahmed6252]

Sir your playlist is awesome

[@Oppostionj_891]

This is somewhat entertaining I love this video I have been having problems with math and now I am able to understand because of you thank very much ❤

[@Zxra045]

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 😅

Gosh... I lost math around 2d grade in Ukrainian school. My first teacher was ignorant twords my understanding so she just didn't care about me, and she focused on thoes who understand everything she says. I didn't understand math since then. After some time i understood basic concepts. I can multiply. But i can not just devide. I just can not comprihand it in timely manner. It takes me 5 minutes to subtract and devide somethung as easy as 567/23 i just can not understand it somehow. I need help 🥲 im way too old to not understand such concept as deviding two numbers.

While memorizing times tables, is overall more efficient. But being able to stack those numbers in your head while takes longer proves you actually learned your times tables and not simply remembered them.
