Years later this video is still helping others. You’re positively affecting the lives of thousands of kids. Saving them from beatings and helping them get better grades, opening their path towards better colleges, and a better future. You are truly a good person, and I am grateful for this video.
Typically because of intent: when you are looking something up you have full intent to learn it. Even when you think you have intent in class, there is always a possibility that something is distracting you with so many variables in the classroom. By coming to this video you actively are focused on engaging in the content rather than someone saying "hey, you need to know this so pay attention." Intent is one of the top factors of success in anything.
OM!!! Honestly you taught this waaaaay better than my own teacher. i couldn't understand a thing in class today, you explained so much. Thankyou soo so so much !! :)
You are welcome. I am glad you found the video helpful. I happen to be a "real algebra teacher." I've been teaching mathematics for 29 years. Wow, now I feel old. ;-) Study well.
Just started my freshman year and have this for homework. I couldn't understand the topic until I decided to look for a video. This one helped me very much! I learned much better here than my math teacher.
thank you for explaining this so simply, my friends and I understand this so much better now, thank you so much you are saving all of our grades in our honors pre calculus class 😂💕
youre under lucifer's dogmas and bondage. Learning is fun and easy as breathing. When youre where youre at, his fallen angels acting as your mind, will and emotions make it not that way.

And short term torment, those feelings and thoughts that fill your mind, while being exposed to it. Welcome to their soiree

Thank you so much for sharing this video. I recently just started algebra 2 and my teacher doesn’t explain. She just writes down the answers. I instantly understood after listening to your explaining! Thanks a ton!
I really do appreciate you doing this. I learn last semester that this is the way to go. It doesn't matter the teacher i have, some classes i will have to find other means and this is it.
Bro, finally and luckily, I found this video! I was only looking for how to set a set notation if two symbols are different and I cant see even one the more I scroll down. But now, REALLY FOR SUCH A LONG TIME TO FIND ONE, I FINALLY GO THROUGH HERE, THANK GOD :) thank you so much 😘 its not that hard anyways, i thought its hard lol xd
Could you make a video using an interval for example (2,6) in set notation using absolute values and set notation? Im struggling with this particular part.
Our teacher does not teach us anymore because of online school, they only make us read five seven paged pdf, so I'm really struggling but you explained everything in minutes and it helped me a lot for my upcoming tests :)
I'm glad you found the video helpful. There are a lot of good resources on the web to help you learn and understand mathematics. OpenStax and Lumen Learning are a couple of them, plus the many videos on TH-cam. In addition to my videos, I recommend patrickJMT, YourMathGal, and Mathispower4u. Study well. You can do it!
Dude who ever made this video thanks👌👌 the way u teach this it helped me out a loooot lol keep up the good work cause u really helped cause the way my teacher teaches it is a way lot different and more difficult but this way it's way more easier thanks
Hey thank you soo much for replying. I’m soo glad you are still here. I’m doing year 11 maths methods from Australia, I was doing Quadratics before but now we are moving into this stuff. I’m still having trouble picking it up but these kinds of videos help me a-lot. Thank you very much again and best wishes.
@@Missie-gd3jw You're welcome. Learning math, like learning just about anything, takes a good attitude, determination, and perseverance. So while there will be times you will have trouble "picking it up," keep at it. Take care, and I thank you for watching.
Can you do a video on set-builder notation and how to sketch a graph of a set notation???? or unless you already made one and i just couldn't find it on your page, could you send me the link??
Thank you so much!! I was struggling to understand this from my professor, and I am a visual learner so reading from a book just was not working for me.
If it's "greater than or equal to" or "less than or equal to" then the value is included. It's the "equal to" part that makes this so. If it's just greater than, >, or less than,
On the 3rd example of interval notation. What does it mean that five is not included? and it should be parenthesis, i get that negative is included but why does five not included? Can someone please explain me right now :(
The numbers don't matter, It depends on what sign it has and on number five it is a less than sign which means it isn't included whereas if you had a less than or equal to sign then it would be included .

Nice video man, i couldnt understand what my teacher was saying at this time and this definetely got me on track, thanks!!
God bless u sir,
The only video that made any sense, u teach well, u actually explain
thx, this has been confusing me when it comes to open and closed sets .now i hav understood the whole concept God bless u
Thank you king, for some reason my prof never told us this even though it would take literally 5 minutes
I'm glad to hear you found the video helpful. Study well.
Wow, my teacher told me to watch this video...and she couldn't just do this on the board? Smh lazy af

Thank you so much! Really helping out with the COVID schooling

maaaan this was soo helpful thank you very much Sir...ur the best everrrrr
my teacher just gives us the work and doesn’t explain nothing so thank you
How can you tell if the number is included or not
If the inequality symbols ≤ or ≥ are used, then the number is included. If < or > are used, then the number is not included.
Why didnt u use open and shaded circe to represent exclu and inclu

When writing in interval notation, how do I know which to write first?
The small one goes first and the big one goes second....sorry being a year late
John Velazquez lol
it goes the lower limit first, then your upper limit. Sorry for being 3 years late.
small one goes first. Sorry for being 4 years late.

Thanks! We don't use set notation in class but sometimes hw needs it
Literally 3 hours before my test helped a lot
THANK YOU MY TEACHER DIDNT EXPLAIN INTERVAL THANK YOU SO MUCH!
how would you write a solution set verbally
THANK U RANDY UR GOATED
You are welcome. Study well.
Thank You so much Mr. Anderson, I was having issues with the Interval Notation, I wasn't sure where to put the Infinity sign.
How about when x is not equal to a certain number? What is it's interval notation?

Incredibly helpful for remembering notation. thank you very much

How do you know when it’s included and not included?
If it's "greater than or equal to" or "less than or equal to" then the value is included. It's the "equal to" part that makes this so. If it's just greater than, >, or less than,
This helped ALOT. Thank you 🙏
Thank you i was struggling with my homework and couldn’t remeber for the life of me
You're welcome. Study well.
How would you write the set notation of a notation going from negative infinity to infinity?
I think it would be { x l -∞ ≤ x ≤ ∞ }
I believe my teacher said it was something like {x|x f(x)Eℝ}. I remember taking notes in class, but I don't know where they are.
I know that set notation and algebraic notation is the same thing so what is the difference between the two if they are the same.
So helpful thank you great way of writing and organizing your examples.
In the last given, can "U" ( union symbol) be used rather than the word "or" for the set notation? That's what I always do.
Darci Fernandez no you can’t do that...at least my teachers took off points if you did that! You have to use “or” or “and”
Thanks for the clarification. It's greatly appreciated.😀
Darci Fernandez
No problem!
I couldn't figure out a problem but I got it after watching this video thanks
This helped so much, thank you!!!!
Thank you so much my math teacher Mrs. Harrop is really bad at explaining this stuff so thank you very much
I need help with this module
phenomenal video! but I have one question, my teacher shows set notation as {x|x€Rx>3} How does this vary from your concept?
I mean {x|x €R, x
Hudman321 I was taught that this is the correct form.
SAME!!! I was taught {x|x Eℝ, x

@@Dude-vp7se maybe but i doubt it, i think a lot of people would be doing this right now :P
What do i do if the problem is 2x≤4 ?
Divide both sides by 2 to get x≤2. See my videos "An Introduction to Linear Inequalities" and "Solving Linear Inequalities" for more. Study well.
