This man legit made me understand more in 30 seconds than what my math modules can do in an hour.
@@imyg5326 where you need to use the union?
Im still confuse a little
depeds module is a fckng horse shit
Ikr
@@adriansaldom7627 some r jiat very rushed only few samples and explanations
I finally understood when the circle will be hollowed or filled. Thank you so much. Hands down to the brief but meaningful tutorial.
literally me
Explain please
@@ayomideadejimi1192 from what I understood, the circle will be hollowed if it makes the fraction undefined (the denominator is 0) or if the sign used is > or
I cannot thank you enough for this. I’ve been in the library doing these problems over and over for 3 hours straight without getting a single one right. 4 years later and your video is still MAJORLY helping students struggling. THANK YOU THANK YOU THANK YOU!!!!
imagine giving 3hours straight without getting a single one
not everyone is a fast learner smart ass
I never comment on TH-cam but i just wanted to thank you for this because we’re in online school for COVID-19 right now and you just saved my math grade from plummeting!!
I am in the same boat, this lesson was hard to wrap my mind around until you showed me this !
He made a mistake on the last example so be careful
@@noohahmed7158 I don't think that there is a mistake on the last problem. I even typed it into WolframAlpha to doublecheck.
i can relate
Crazy covid was 3 years ago, still a thing tho in late 2023 yet not that bad
Bro teaches better for 10 minutes than for 50 minutes in school. So complicated in there. Thanks!
Exactly.
I just started uni, and it's been a week that I tried to understand the last step of inequalities. my teacher spends an hour explaining it and it made me hate it but this legend made it sound so easy. keep up the good work, you are a hero.
@TwixX. did we ask?
Mashallah
When the example for the video is the same exact question that's on the homework.
LOL
Youre lucky
You couldn't 🤣hide your joooooy

Tbh the best maths toutorial on YT. Keep it up man 🧐
bro why is it he uses parenthesis in 3 > x in 2:32
@@jeraldferrerr because they're not including 3, so it's an open circle.
I am a high school math teacher and this video was very well done!! thank you!
Short, sweet, and understandable explanation. Perfect video!
Yaaaa♥️♥️
Words can't even explain how thankful I am for you, man. Your videos are single-handedly saving my math grade. I have a college exam this Friday, and I've been trying to figure out how to do this, and now I finally get it. You're a legend. Thank you.
Pre-Calculus 1st exam tomorrow...
Procrastination will forever be my bane, and I shall repeatedly see myself in this channel more in the future.
I learned more a lot here than in school ☹️ Thank you so much! 😭😭😭
bro you literally have a video for everything! very impressive.
I just wanna say, I love this YT channel so much. Thanks man, you deserve a million subscribers
I can't fully understand the teacher teaching us and now finally I can understand when u explain it, thank you dude so keep it up and use ur talent to teach other peope
I clicked the ads just for you. Thank you ^100
you are without a doubt the MVP of 2020. You have helped me with Chemistry and now some Algebra. Thank you.
Oh God, I'm so glad you existed! Everytime I have a problem with the subjects you are there! A life saver.
I must be really stupid i guess, not even the greatest teacher on the internet can make me understand this
Same
Dang, same bro
Same bro hahahaha
Really helped me man, the most useful 10 minutes I have spent on phone the whole 2020 and 2021
bro I've literally been looking for a video to teach me this for days and you managed to teach me in literally 2 minutes. Thank you so much
this tutorial is what I need now because 5 hrs later is our first quarter exam and this is were I study my pointers now Goodluck self
i dunno why but from now i have ultimate respect for you
did you passed?ʕ º ᴥ ºʔ
The first one minute fixed hours and hours of suffering with inequalities, thank you so much!
Gonna learn this just for the contribution for my Group's Reporting
Thank you so much,you made it so easy....I have my exam today in 4 hrs
MR. Organic Chemistry Tutor , thank you once again for an incredible video on Rational Inequalities. I really understand this topic much better than when I took precalculus in the 1980's.
This helped me a lot, I can't believe I understand it now after watching you teach it compared to my teacher teaching it. Thank you!
Thank You..
thanks bro I learned more from you in under 3 min rather than my teacher explaining this for 40 mins
this man has the most assuring voice
Thank you so much. This method was so much easier than the one my teacher showed us. Thank you!
Thank you for this helpful video 😁😁you have been my teacher for a long time!!
Hello Danily sea. What class are you in?
Honestly, he’s my pre calc teacher at this point he explains it much better
This method is more simple and efficient than knowing first the set notations, interval, and test point by making a table.
Sir you are a saviour, i couldn't understand any single thing about this in my class. You made it clear as crystal.
i cant believe he doesnt have more subscribers he has the most helpful videos!!
I have a great teacher, but I just use your videos to brush up on certain topics. Thanks!
You don't know how much you've saved my life thank you sm for this video. May angels continue to look after you
Thanks man,this video help me to understand the topic,my teacher explanation is way more critical and hard to analyse but yours is so understandable
thank you very much , it made me understand more in half an hour than listening 1 hour to our class
This video just saved my life! Thanks
ON MY OWN OPINION THE WAY YOU TEACH IS SO FAST.
The best math tutor on YT
That's fantastic how your explanation style is so simple and so understandable ❤️🌸
Because of you I am passing Pre-calc, you're awesome man thank you!!!
Hope all☹️
Simply wow.....I was struggling over this topic for a while...thanks for great explanation! :)
Man thankyou so much, you give examples that aren't basic, as well as the rational equations
organic chemistry tutor is is the best
very helpful thanks so much uncle organic chemistry
One of my massive confusion has been clarified, thank you so much !
Bruh bruhhhh ITS BEEN 2 WHOLE DAYS...TWOOOO!!!!!!!!!! And this gentleman made me understand Rational inequalities in just under a minute.
Everytime I forget it, I just go back to this video, thx dude
Thank You.
I love you mister chemistry tutor
its amazing that you have a video on every topic i could possibly need help with!!
Mark my words, I will have this man's children.
Doing Gods work 🙏🏻🙏🏻

I will follow you till the end your the best at giving math examples that are really hard.
Best tutor of all time
this man be saving lives
He's my teacher!
Pre-Cal Gang rise up
your videos are my saving grace for college entrance exams
Best math teacher hands down
The first example was the same one as on my homework. Awesome.
Man....I LOVE YOUR VIDS....YOU DESERVE MORE SUBS AND VIEWS!!... THANKS FOR THE EXAMPLES!!..YOU MADE ME UNDERSTAND IT MORE THAN MY MODULAR LESSONS DO....KEEP UP THE GOOD WORK!
You have been a great help to me since before up until now, you deserve a great reward man!!
I cant express joy betterin text..your my hero
Thank you brother you solved my basic maths easily.. I am preparing for a national level competitive exam and your video solved my problem... Thanks so much💓💓💓💓
I dont know what to say but i really thank you for this anazing explenation. From UAE.
I don't understand at 7:32 when you say, "The denominator can't be zero, so it can't be negative one." But then you use the number one anyways. Where did this new one come from?
seriously not even trying to over exaggerate but this is better than my university
Thanks to you I was able to answer on my quarter exam love ya man keep up the great work
Bloody hell! Light bulb moment! I've been struggling with these trying to see them in my head. This method is so simple and makes complete sense. Pity my textbook didn't explain it like this
This makes me understand the lesson better 😭 You just save my life!! Thank you 😊💖✨
i finally understood some points here in ur video about our lesson, but i still cant answer my homework because the numbers/example given in our homework are a lot bigger and more complicated than your examples. And I can't even ask anyone for help because I don't know any of my classmates. Even math reminds me how alone i am lmao fml
thanks man you're awesome
Best channel on TH-cam.
The way you teaches it makes math easy for me 🙏🙏🙏🤝
I can't thank you enough. You deserve government funding.
maybe that's not enough. he can also have my college fund.
Thanks man thats really helpful , u really made me succeed in my math exam 😅👏👏👏
thank you sir
thank you. i always come back for this explanation.
Thanks you for teaching me other way to solve these inequalities
He is a legend btw…
This helped me so much to build my skills!!! THANKS
Thanks again i learn alot hope i pass my test
All I can say is. Thank you😭 You made the whole module made sense by just a minute😭
Nice video. I speed it up 2x but still understand the whole process. Cool. Thanks
Man I cant even get started with this, our math teacher was plotting dots here and there and proceeding with the signs table without giving context about the number line so I got confused, and from that point on I didnt understand anything on what was happening so I just left class feeling like a piece of dumb sht. I never really comment on vids like this but I'm super thankful rn to the point that I'm typing this out. Thank you. So. Freaking. Much.
Much appreciated sir
I love you organic chemistry teacher❤❤❤
Thanks a lot! It is so easy to understand. But could I have another question? What if there is no 'x' at the numerator? For example:
2/x²+1>0 [or 2 all over x² +1 greater than 0]?
...how could I plot it in the number line? Thanks in advance!
Lol I can only get
-1< x square < infinity
i < x < infinity
I actually love u
Thanks bro ur better than my teacher
This helped me with my midterms
