I have noticed a thing. a physics video(I am 6th grade)= 9 minute video a math video(6th grade) = 2 or 1 minute video Why is it so? Can anyone answer me? (BTW) I know that this is out of context, and I maybe dumb, but I am just curious)

I think that for the math videos Sal is working through math problems to show a concept and that doesn't take very long, whereas the physics videos are explaining ideas. I'm just guessing, but I hope that helps. :)

where in PEMDAS is absolute value?

Absolute value is in the grouping step of order of operations, equivalent to parentheses. I prefer to use G E MD AS for order of operations. Grouping Exponents Multiplication/Division Addition/Subtraction

Lesson 7: Comparing absolute values

Placing absolute values on the number line

Name: Placing absolute values on the number line
Uploaded: 2015-02-04T00:57:52Z
Description: In this math lesson, we learn to sort values from least to greatest using a number line. We practice with negative numbers, positive numbers, and absolute values. By plotting these values on the number line, we can easily identify their order and improve our understanding of number relationships.

I still don't understand why negative numbers have less value if they are at the same distance as 0

  They are less then zero, lets say that I hade 2 cookies, my friend ate them and said Give me another one. I would be in debt of 1 cookie, or I had -1 cookies. Think of it as zero minus a number.

  If the question is, "What's the absolute value of -27" then the answer will be +27 because absolute values are never, ever positive.
  
  -27 is not 27, but their absolute value is 27.

Video transcript

What we have here is four different values some of them expressed with negative numbers or absolute value, and what I want to do is sort them from least to greatest, where the least is on the left and the greatest is on the right. So sort from least to greatest. And like always, I encourage you to pause the video and try to work through it on your own. So assuming you have, you had a try at it, so the easiest way I can think about it, well let's just, let's just plot them all on a number line. And you might want to draw it out or eventually you kind of have a number line in your head, and you can think about it that way. So let's first think about the absolute value of value of -27. So what is the absolute value of -27? Well it's just going to be +27. This right over here is the same thing as +27, because -27 is 27 to the left of 0. 27 to the left of 0. So let's plot the absolute value of -27. Well it's really 27, so it's going to be right over here. So that is the absolute value of -27. It is +27. Alright, then we have -17. Well, -17, let's see each hash mark here is 3, so this is -9 and -12, -15. So -17 is gonna be right around there. So that is -17. And then we have -28. So we have -27 and each hash mark is 3, so -28 is going to be right over there. -28. And then finally we have -22.4. So let's see, we have 18, 21, 22 would be here, so 22.4 is going to be roughly right over there. So that is 22.4. So if we want to sort it from least to greatest, well, we just have to start at the left end of the number line. The smallest of them, or the least of them, is -28. Then we go to -17. -17. Then we go to 22.4. Then we go to 22.4. And then we go to the absolute value of -27, and we are done.
