Absolute Values: Defining, Calculating, and Graphing

What are these funny little brackets? They represent absolute values. What's that? Well are you here to read this, or watch the clip? Let's go?

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

Man, it's already been a month since I started watching your vids on geometry and algebra and I can already feel the smartness oozing out of my brain.🧠

For anyone struggling to find the last two comprehension. Know that before you start trying to solve x, you have to get the absolute value by itself. Example: |2x +8| -2 = 14 becomes |2x +8| = 16. Now from here you have to split it into two equations, |2x +8| = 16 and |2x +8| = -16. From here you can just simply solve it like before. Goodluck

i grew to love math because your videos made me appreciate the beauty and importance of the subject. just a little more and soon, i'll be laughing my ass off at some math jokes 🤣anyways, thank you so much, professor dave! please continue to feed others with knowledge and curiosity :)

Answer of 3rd comprehension (negative case) :

We start with the equation |2x + 8| - 2 = 14. Substituting -(2x + 8) for |2x + 8|, we have -(2x + 8) - 2 = 14.

To solve this equation, we simplify it step by step:

* Distribute the negative sign to each term inside the parentheses: -2x - 8 - 2 = 14.
* Combine like terms: -2x - 10 = 14.
* Add 10 to both sides to isolate the variable term: -2x = 24.
* Finally, divide both sides by -2 to solve for x: x = -12.

Hey Prof. Thank you for the work you do, very much appreciated. Will you look into discreet mathematic topics. I would love to see your video tutorials on topics like logic, truth tables, combinations, series and sequences or any one of these. Thank you

How does he knows everything, like literally science, maths, psychology, space stuff every subject that I study, what are his study qualifications?

Hello Dave, can you explain me what is the application of this absolute value

[littleretroship]

1:10 does it apply to imaginary numbers? If so, how does it work, does -i become i or does it become something like -1 or 1.

I can feel the math coming inside of me

[rahulchittur]

Are you going to make videos for inequalities?

[junaidsabri]

Sir can you explain curvilinear coordinates ??
I will be thankful to you🙏

[arkanrb]

am really stunned with the comprehensions always couple of them doing them wrong and cant understand if it me doing something wrong or incomplete info how to solve them in the video, read all the comments seems there is another way if its with another variable and needs to evaluate if the absolute value is more or less than 0 to apply the negative it seems the correct one but how to implement it dont know hmmmm

[intriguingstories]

for the 3rd question l2x+8l=14 i keep getting 4 and -10 not 4 and -12 any idea why?

[ridmicmeena]

Can anyone explain how the last two Questions are done

[mattbodie]

I did not get the same answers for the last two...No idea why

[gloriasarkar]

Can you please help me solving this
