Set of Real Numbers | Subsets of Real Numbers | Set Symbols in Math [Animated] - Pre-Algebra

This is an ANIMATED MATH video explaining the "Set and Subsets of Real Numbers" that is VERY EASY to FOLLOW and HIGHLY RECOMMENDED for struggling students. This topic is a prerequisite for algebra.

Subsets of the Set of Real Numbers:
00:00 Welcome!
00:15 Set of Natural Numbers: ℕ
‣ Counting Numbers
00:37 Set of Whole Numbers: 𝕎
00:55 Set of Integers: ℤ
‣ Negative numbers
01:16 Set of Rational Numbers ℚ
‣ Ratio of two integers
‣ Terminating and repeating decimals
02:07 Set of Irrational Numbers: ℍ *UPDATED description*
‣ Cannot be expressed as ratio of two integers
‣ Non-terminating and non-repeating decimals
‣ UPDATE: There is no default symbol for the set of Irrational numbers. References or authors use their own notation, like what is indicated in the video.
Formally, we can define this set using:
ℝ∖ℚ or ℝ−ℚ (the set of real numbers minus the set of rational numbers).
03:00 Set of Real Numbers: ℝ
‣ Set of Rational + Set of Irrational Numbers
03:16 And there you have it!

Thank you, worth to share. Last week nagpapaturo sa akin pamangkin ko sa algebra. Perfect timing! Nakalimutan ko na rin kasi.

[intralifestylebaguio]

I really appreciate this video mas napadali intindihin at mas malinaw na naexplain, kahit ako na review what are they called. Very informative and helpful math video

[MonzMelecio]

This is very helpful especially now na struggle is real talaga lalo na sa modular. My niece is having a hard time, sariling sikap matuto. Will recommend your videos to her.

[iAGRIbySIRDAN]

this video will help teachers in their lesson...this amazing it will catch the attention of the kids because of the animation.

[wendyflor]

Watched this with my son so we had to make pauses every now and then... This is helpful. If the learner needs more guidance, a parent or guardian could be beside him/her. Otherwise, it is easily understandable.

Such a nice content po.malaking tulong para sa lahat hindi lang sa mga mag aaral.keep posting po

[elieli]

Oh I love how did you present the graph/chart for teaching and explaining what are the sets and subsets of real numbers

[elikalokaloka]

I'll share this to my friend who's teaching Math so that she can sahre it also with her students as their reviewer aside from their modules.

[BoredDadEldrich]

This makes mathematics fun to think about and learn. This is legit. Keep it up!!!

[andrielawrencevillocidoign]

im from philippines, thank you for the short video but has the complete meanings

[wanderwomom]

i commend your videos!! they are really crystal clear and very easy to understand. videos like this are really a big help especially to those who cant afford tutors.

[DawnLyndelle]

I'm so glad I'm done with algebra! Hehe! Once I have a younger cousin who needs help, I can always go back to this channel. :)

[marvinramos]

wow, this makes our students easily understand math.. this is nice.., thanks for sharing

[EvonneClaudineFP]

Very informative. This will help srudents who are a bit confuse with Math Subject. 😉

[jersonfedelino]

So informative people who will your videos will be get more knowledge abd additional tips on your videos keep it up .

[BeJentel]

Very nice computation, Can share this to my niece. This time the content wil help them to study this subject.

[raemonique]

For someone like me that's not very good with Math finds this content very interesting 😊

[fullyhousewifed]

my kid was telling me about area and recognized the irrational numbers and other terms. pretty helpful stuff. I don't do math so much, but the kids do have to learn them, so i've got them with me watching this. (i even have a video haha!)

[teamuytravels]

This will help students understand more about real numbers. Nice content by the way. Thanks for sharing this to us. It helps us study math.

[blairvillanueva]

I'm not into detailed math, and I admire the reason why I passed the math examination because I know how to seal the deal. But this video is very helpful for students in all year level.

Do you accept online tutoring? Australian parents pays good $ just to guide their children.
