Large Whole Numbers: Place Values and Estimating

So there are a lot of numbers. An infinite number, in fact. So how can we possibly have a symbol for every single possible amount of objects? Well we don't need to, because of place values. With these, we can use just ten symbols and represent every number imaginable. Check it out!

This guy basically completed the every unit of math in school up from kindergarten to twelfth grade in just a bunch of 5 minute videos.

Thank you for this series (which must have been a considerable amount of work).

[klutzy_]

This is awesome work! I've downloaded the whole series..going to complete the series within 3 months.

He's so good that I dont even speak english well and he stil can teach me how to think about math. HES A GENIUS!!

[bigaaron]

Thank god for this series. I dropped out of college a few years ago and I want to go back but how much I've forgotten on math dissuades me.

I don’t usually comment, but this is overdue. I haven’t studied any Maths for 12 years as I worked in a field totally unrelated to Maths. Now, I am considering a career shift to programming and realized that I forgot everything that’s why I ended up studying your videos. Another thing is that I studied Maths in another language not in English and thought it’d be difficult to study in English, but you made it simple. And to find all of it organized in one playlist with logical, simple, a step-by-step manner is satisfying my OCD😅. I am still in the process of studying for my career shift and hope I would make it within the next two years. Thanks a million professor Dave ❤

Ive learned more about math in these videos than i ever learned in elementary through highschool. Thank you.

[siao]

if my teachers taught math the way you did, I wouldn't hate it so much. I'm finally understanding it, thank you!

[Vampire]

If I had not been found this channel. Me returning to the caveman's intelligence wasn't no where thin... thankyou you made me have interest in maths again:)

[Jasmita-]

Thank u for the awesome session professor Dave!

[mexitechnology]

i like to know if you have or in the future have math classes i'm learning math and physics. still in basics, thank you for making these videos

[gajendernegi]

Thank you for this series and help the maths work

[AnatoliiSkidchenko]

Hey there! I really appreciate how clearly you explain everything. It makes it super easy to understand.

Prof Dave I just watched my First 3 Videos and i Know this will be Epic! HUGE THANKS FOR THIS GREAT INPUT TO HUMANITY!

[skyliethejamaicangirl]

[EcclesiastesLiker-pyts]

Informative! Great to begin at the beginning!

[mayarmeselhy]

I decided to give up and go watch some YouTube vedios then i saw your channel and im truly thankful for that i won't give up again ❤

[elmzatamz]

i like this video is he can tutor one on one ?

For context this is for my memorization purposes and do not intend to become creepy





Professor dave here let's Talk about place values


Wheb we started countingnthings thousands of yeard ago we quickly realised that number's can get very big very fast, whether your counting grains of sand or stars in the night sky


Summing up, we made numbers work how they do csuse if we made unique symbols for every number we wouldnt be able to remember them all


There for we couldnt give every possible number its own unique symbol

We needed some kind of system that uses a small collection of sumbols over and over

To repersent very numerical value immagineable

That's why we came up with the notion of place values

Say your again counting apples

You get one two three all the way up to 9

Then when you hit ten this becomes a two digit number

That's because we place a one in the tens place while the units place goes back to 0 and starts again

After it gets to nine again the tens places goes to a two indicating that we've reached 10 twice while the units place goes back to zero
This continues through thirty fourth fifty and when we reach ninety nine we've maxed out both the units place and the tens place

So we have to add the hundreds place

We place a one here indicating that we have reached one hundred while the other two places go back to zero

This process can continue ad infinitum

Every time all the digits reach nine we add a new digit to the left a one while all the others go back to zero

Thousands place ten thousands 100 thousands millions and so forth

This is a brilliant system because it allows us to repersent any number imaginable using the same 10 digits from zero to nine just

I'm combination that demonstrate various magnitudes

The place glaues where these digits can found indicaties how big or small the number is

I was so bored and i found that i'm gonna learn Math from 0 to 10 with English and this is the best video series i found. (i never learnt math with English before).
