Algebra 6 - Interval Notation and the Number Line

Although Venn diagrams are a useful way to visualize sets whose elements can be any type of object, interval notation and the number line are best suited for describing sets of real numbers used in Algebra.

Thanks for this video !! I'm very happy because of you !!! 'Cause I'm like someone who is a slow learner so I always feel left out in our class . Because of that I always work harder so I can keep up with them ... sometimes---I mean usually ... when my teacher lectures, I can't understand some important details ... and too shy to ask .. since I got a terror teacher .. I always have to watch vid like this everyday to understand it completely like how my classmates understands it ... And I just got lucky to find you !! I don't know if this is coincidence or what but all the vids you posted is all our topics in Grade 7! It's in our modules !! 😆 !! Because of your vids I can now do advance learning without problems !! Thank you very much !!!

without these videos, I would never have any interest with maths...Thanks much please keep this posts till my two children grow up coz I'm gonna show them your videos

After an extensive exploration of both on annd off line resources on naive sets and abstract algebra excluding Zermelo Fraenkel approach overloaded with lots of complicated and/or perplexed expression showing the intelectual superiority of the authors rather than giving new refresing and useful insights into reasoning, I have Finally & Fortunately come across THE BRAINIUS MAXIMUS and must exclaim:

I like maths in my language (greek) and I think it's very good. However, I had never thought that one day I would have found a lot more entertaining and useful to learn in english, let alone in animated teaching!! Really good work!! Thanks a lot!!

WOW - well done - Brilliantt Brainium at work in every aspect of the Universe of Discourse in the Ars Logica, Mathematica etque Linguistica. I am simply unboundedly lyrical. THANK YOU VERY MUCH indeed. A remark: as a former pupil of a European brand of schools I praise MyWhyU wise choice of notation symbols, in particular using the sqauare brackets in interval notation.

What is the difference between number lin method n set notation

[sofiac.]

find the set
{(-∞, 2) ∩ [-3, 4)} ' and express in interval notation

how to answer this?

hi, forgive my trivial question. I noticed you said "having values greater than OR equal to zero and less than OR equal to three." You didn't say equal to zero AND equal to three. I assume x can not be 0 and 3 at the same time. Am I correct? thank you so much for these splendid, exquisite courses.

So if this is a learning vid, how come the symbols for greater than are the same as the symbol for less than? I even googled greater than is open on the left, and less than looks like an open L. Smh.😖😒😕😞😮😭

This video are kinda addicting to watch.

These algebra concepts are technically analysis level lol
