I know this is 'easy' stuff. BUT this is why I believe I need this. I was belted and shouted at so many times in all the years of maths (at school) for asking for things like where did maths come from, fairly basic questions for kids you'd think It actually makes recalling how to add and other basics really hard under pressure (like when there are fractions or any conflicts in the room!) because of the many teachers who had nothing to give because they in turn had also been badly taught. It's resources like this video where maybe there is a chance that I too am allowed to know some of the mysteries of the universe that educators of several generations in the last century made sure to deny access to.

This video doesn't cover the basics at all. Or rather, it only covers the basics and NOT the fundamentals. No great mathematician would ever learn/understand numbers like this. The first question that arises is about the nature of quantity, then digits, place value and so on. These are the fundamentals which no one covers with the detail that they deserve. This half-assed, lecture/information/rule based teaching and learning is the primary cause of failing at higher levels since the fundamentals aren't undestood. It took me an effortful and strained 5 hours over 3 days to fully understand what I just mentioned here, yet it's treated as some random thing. In fact, you cannot truly understand addition or subtraction without them. You can only practically utilize numbers, but you will never understand them. Conflating practical utility with understanding is a huge error made by nearly all. All that's to say, my friend... You need to look even deeper than this. You will NOT understand Mathematics like this. I've fallen for this trap earlier on as well. I've also had trouble with fractions or hell, even division. All because I didn't understand things properly, only at a utalitarian level (as is taught in all textbooks and schools). I hope you delve deeper and improve, math is quite amazing when learned properly and when explored and not glossed. Good luck :)

Hard to know what you've forgotten until its sat in front of you equal parts familiar & new.

I too am studying mathematics, albeit for a different reason. In the past, my instructors failed to cover fundamental concepts and instead delved into advanced topics. While I don't hold any animosity towards mathematics, I received insufficient assistance to progress with algebra. I hope you are able to acquire a thorough understanding of mathematics.

You might think that because this is Kindergarten math it might not be interesting, but when you learn it in Kindergarten they don't explain the "why" to ANYTHING because you're a stupid, wild child who needs to be bribed with gummy candy to sit still and do your homework. Explanations go over your head. By the time you're old enough to comprehend any you're already out of school and so unless you refresh yourself it remains unexplained. All of this means that, even though I know what 2+2 is, this is still blowing my mind. Explaining what equation means, WHY something subtracted by another is what it is, instead of just saying THAT it is, all of that and more is completely glossed over when you first learn it. Learning it for a second time here is, again, blowing my mind.

I’m just starting out with this series. I’ve been through college algebra/trigonometry formally and used trig and algebra fairly often in my career. Now, I’m retired and trying to brush up on my science education, but I find things either too simple or I don’t understand the math. Hopefully, I can get refreshed back to where I was, though it was 35 years ago, and go beyond. I’ve always found calculus a bit mystifying, as well as anything beyond. But, I like your style of explanation, and find I can understand what you explain pretty well. Thanks in advance, Dave!

Honestly, I’m not super lost on math but there were some little (but important) things I missed out on due to things completely out of control. I’m a sophomore now, and I had not been taught division and knew very little multiplication. Year after year, more and more was added. Being asked to build a house when I knew nothing past how to make the foundation. I’d be embarrassed when confronted, but also far too embarrassed to explain why I didn’t know. My childhood wasn’t golden, and it is something I found myself wishing to hide for a better image. I don’t think it helps that my brain has trouble even processing normal things. I’d been treated badly by a lot of people and now you could tell me the sky was orange and I’d doubt my eyes in favor of your claim. I’d feel the need to believe. You know whats terrible? I was shamed and they moved on. No one took the time to teach me. And I felt dreadfully ashamed to look it up. I got over it though, and here I am. No matter what it was that brought anyone older here, It's okay! We all have reasons and you being here and wanting to learn on any of these is wonderful. Lots of us had no control over it and no one took us back to the opportunity. I promise you all that math can also be fun, and very pretty when done correctly. (I love how it looks, and how nice it is to complete something complex) I’m proud of you. Refresh, relearn, or start-up. It's all very good.

Since I started school, I've fallen behind. I would miss at least a day of school a week. Then it turned into 2, then 3, 4, and then I just stopped going. The last time I was properly in school was year 6. 4 years ago. I mainly stopped because of how bad my math's was and I was too embarrassed. I've just started homeschooling so now I'm relearning math's. I'm going to stick with it and now that I understand how important it is, and actually have a little interest in it I'm going to learn.

but dave i learned subtraction is associative because subtraction should added separately 5-3-2 => 5-5 =>0. you can't do 5-3-2 => 5-(3-2) because 3 and 2 has minus symbol. To do in correct way 5-3-2 => 5-(3+2) here, i took minus has common outside the bracket =>5-5 =>0.

You are proving that subtraction is not associative by writing all that.

Dave do you recommend watching all of these videos for someone getting into computer science. I don’t know where to start and I’m pretty bad at math
