Multiplication and Division of Small Numbers

Показать описание
What came next after addition and subtraction? Why, multiplication and division, of course! Multiplication is kind of like addition, really. In fact, it's just repeated addition. Take a look at this early innovation in arithmetic, and the properties associated with these operations.

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

finally, a full math course starting from absolute basics without treating you like you're 5 years old

I wanna learn Calculus. But somewhere in Grade school I missed catching up Math. So Im gonna start here.

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! 😃

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

Me calculating a formula: Damn this division is annoying. Let me just use a calcul-
Professor Dave: 5:12
Also me: Nevermind...

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! ❤

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

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..

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.

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

I’m a senior in college. A philosophy major with a minor in chemistry about to graduate and I’m looking for a better foundation to understand Calculus applied to Metaphysics and Dimensional Reality. Refreshing my mind with the basics

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

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