why did you not change the sign for that equation at 17:30 when you multiplied 12 by -2, is that not mutiplying or dividing a negative number, meaning the sign should have been changed to
Hi sir! i think in 24:48 we should use brackets instead of parenthesis? Correct me if Im wrong, thank u sir!😊
During my time as a gen z, I've learned that despite having a good math teacher, TH-cam will forever be essential.
Yessirrr
Preach
Literally in Nursing school rn and TH-cam is saving my life. I haven't touched this material since high school tbh, but with the help of Organic Chemistry Tutor and TH-cam, I'm able to understand
Yep I’m literally in the advanced of my whole school but don’t understand what my teacher sayin
Period
How tf is this better than online school, an entire system set in place beaten by a guy and his soothing voice
That is because school is a waste of time
Let's throw society away
right, and its free
On god
@@NoReplyForIdiots agreed 100%!
You done taught me a whole new semester dawg
i don't believe that a math class would teach intervals for a whole semester unless you're in literally sped math. My calculus professor finished this section in literally less than 5 minutes.
@@PHILLYMEDIC69 I'm learning this for a semester😂
dog it’s called a joke >.
@@PHILLYMEDIC69 in what grade
tiny if you are even covering this in calculus your sped
You are so famous on my campus. No-one understands our math professors. I don't know where they receive their techniques. We would fail if there wasn't the Organic Chemistry Tutor. Thank you in Jesus name I pray for your health and strength to recieve your svoluteer services.
AMEN. We would truly be lost without this blessed man's channel
Same to me
A- men I should know
I have an inequalities test tomorrow and I barely know what to do.
@@dlatrell I also have a Engineering dynamics test tomorrow but donot learn any thing yet
I just want you to know that you are one of the only reasons I’m able to pass my classes and finish my degree. You touch so many lives and so many people benefit from the content you have put out there.
Great comment
Nah fr real thou, I'm taking calculus and this man including Mario, and Brian McLogan have helped me remember algebra stuff by so much. Like damn.
wait u all are learning this in degreee?? why isnt this high school things
@@kyubhi They're in high school too. We just forget these and have to come back for review or our high school teachers don't explain things well. As I'm writing this, I still don't understand the absolute value but the problems he works on helps me understand how certain domain and ranges work.
facts
Can we all talk about how good this man is at teaching?
My math teacher makes math so confusing. I could learn this on youtube in 2 minutes
you mean 30 minutes and 43 seconds?
@Aidan Han no there is a video on this topic thats 2:00 minutes long my teacher left a link for us on the school computer
@@elizabethivezaj7384 the majority of the video is just examples so not necessarily
This is honestly better than Khan Academy. Thank you so much, I'm taking Calculus I in college right now, and haven't taken a math class in 7 years (I'm a returning student at age 25). I had taken Calculus before but I haven't used any math in that entire time so I forgot almost everything. I've been really scared to try and do anything in the class because I felt completely lost because I had forgotten the prerequisite knowledge. I looked up some other review videos and realized I had forgotten how to do many things, even as far back as dividing simple fractions. Your videos are by far the most clear and straightforward that I've found, so once again, thank you very much for helping me out. I will recommend your channel to anybody who is going to be taking a college math class and needs review!
I can't say how thankful I am to have people like you who take the time to teach others who need help when their teachers don't know how to!!
And this is why I'm on TH-cam so much, because my teacher can't explain to save their life lol
and 1.75x playrate is literally divine
Exactly
this man helped me with hw i was crying over no cap he did more then my math teacher
Learned more from this than 2 hours lecture. Thanks! May God bless your lovely soul!
From my highschool days, I think I have the perfect judgement to say you are the best in tutorial concerning Mathematics and Chemistry. We appreciate your efforts allot. I'm always being the best in my classes because of you.
I usually don't leave a comment, but I will say ur lecture is amazinggggggggggggggggg
Thanks
Your teaching is a model of clarity, focused and logical with not a wasted word. Thank you so much.
Everyone is saying their in college I’m 13 and learning this wth is this as hard as it gets 🙀
Ikr
Crackhead Energy i’m 12
No it’s just that the school work is slowly getting harder
same
I'm 19 learned this around 8th -9th grade just forgot.
I could listen to your voice for hours and not get bored
amazing voice :D
hes got that sexy latino voice
Anonymous
😂 omg
Thats geh
i luv his voice too ._.
Bro, you’ve helped me through math, chemistry AND microbiology classes at this point. Lol 🙌🏽
I dont know how I could have such a miracle in my life. I hope you are being paid becuase you teach math on a whole new level.
Your videos are the only reason I can pass my exams. Somebody get this man an oscar for helping millions of doubtful students! :)🏆
you were the reason i got amazing marks in math, chemistry, physics and biology. last semester and you'll be the reason I get amazing marks in them this semester
You are a lifesaver!! I have NEVER been able to comprehend OR learn concepts in my class, until you!
Whenever I receive a new maths lesson/exercise from my campus tutor, I ignore my tutor's instructions and come here instead. There is something very soothing about 'the organic chemistry tutor' voice. He speaks slowly and calmly so there's no pressure to learn, only encouragement. He knows how to take potentially frustrating things and break them down so anyone can learn them in a short amount of time.
Thank you so much for taking the time to make these videos. I am near 40, have started college for the first time and am majorly struggling with College Algebra. These videos are helping me understand so much better and I appreciate them!
You don't know how inspiring it is to me when I see someone older than me back to college and not worrying about being late.. I'm still in my 20's yet stress out a lot about how late I am starting college actually I failed couple times and changed my major so there are days where I'm just depressed about it.. I hope my comment doesn't come off wrong I genuinely wanted to thank you
@@jazzyjaz9798 update?
Thanks for this.
I noticed you made a mistake at 24:48 when writing the parentheses for the intervals. One of them was supposed to be a bracket since it's a greater than or equal to sign and the circle was closed.
Yes, i also noticed that and was wondering if it was a mistake or if i suddenly forgot some implied rule
you're the best of the best! you explained every angle and all different takes of solving the inequalities. Brilliant video. Thank you loads!
You answered every question I could have had about this in the simplest way. Seriously thank you.
This is literally helping for my SSAT exam. Now I can solve those SSAT problems which I wasn’t able to solve few weeks ago. Thank you so much
I find his voice so soothing...it helps me learn.
My man out here doing the most teaching me what teachers could never!!! Thank you❤️
My math teacher needed 2 months to teach us all these, and this you just explained it amazingly in 30 mins
dangggg an hour of lecture and I learned nothing now im just 10 minutes in I already finished half my homework. wHAT WILL WE DO WITHOUT U :
big thanks to you! i used to be quite afraid whenever i see fractions but im more confident in answering them now
My guys better than any math teacher at this point, I didn't even get through 5 minutes of the video and I understood everything thanks for the help!
Honestly 3 months of maths grinds all for a 20 min video that made it click instantly honestly just follow along in your copy and don't be afraid to pase and rewind but as soon as it clicks it clicks
Your tutorials are the absolute best!! Clear voice, no crazy side noises and straight to the point! Thanks man😊

ur legit a life saver please pray for me i have 3 math exams today
I will don't worry
You're a life saver, my teach skims through chapters like we've already studied them before
I could not understand this particular topic for months. After watching this video I have understood everything in it. Thanks a lot.
This is helping me refresh my math skills after 14 years! You rock!
Thank you so much! This video helped me understand inequalities a lot better!
yo I gotta admit man, MR JULIO GONZALES you're something else. you made me understand this in just a 30 min video but my maths teacher failed to make me understand this for 3 days but you made me understand in 30 min!!!! You're a legend and last year I managed to get level 7 on maths and physical science because of you, I just wanna say THANK YOU MAN AND GOD BLESS YOU
great stuff sir. I recently got into university and I've been getting overwhelmed by the amount of work I have to catch up on . thank you for doing what you do
2020 ANYONE!!!
Peaches Sunshine-2020 :D
SHUT. UP.
Ha! What a coincidence!
@@tod4849 yeah what a coincidence!
Peaches Sunshine stfu
EY YO I LEARNED MORE FROM THIS THAN MY ENTIRE SEMESTER.
THIS.
Thank you bro. I'm going to be a freshman in high school next year, and decided to test out of Algebra 1. My school really didn't give me much, but two pieces of paper and a text book that would take me a century to understand whatever the hell is in that book. It has no examples that are actually used in the class so it's basically useless. So thank you for your teachings. Their definitely going to help me in my journey into advanced classes.
24:54 should the -2.5 and 5.5 have brackets or parentheses?
dude legit made this waaaaayyy more simple than my online math teacher , im mad i wasted 5 hours of my life watching my instructor make life harder than what it already is lol
I'm 8th grade and I'm from Azerbaijan.Thank u so much,amazing video and amazing explanation❤
Thank you for your hard work, you made the notation part sound so simple and easy to understand!
OML THANK YOU SO MUCH I WISH YOU WERE MY TEACHER!!! Exams are next week and this really helped!!!
at 24:54 shouldn’t the answer be
“(-♾️, -2.5] Ｕ [5.5, ♾️)” since the signs are “greater than or equal to” and “less than or equal to” ?????????? ??
sel ;-; you have the correct answer, he did a mistake. leaving this comment if anyone else wondering...
Imaginr writing 10 question marks over a tiny mistake that doesn't even matter.
@@anthonyjoshua6694 Dude, it does matter. Don't get me wrong I love Organic Chemistry, but if there weren't comments correcting his mistakes, some of the people who are learning this might make the same mistakes. I use the comments to ensure that I don't overlook any errors.
@@Cat-rr3ey Ya I completely agree. Its a good showcase of how no matter how meticulous you are everyone makes mistakes so you should ALWAYS check your work.
I too love this channel
hey sir how about if the given is 1/x >10
Thanks so much! My class has a math test on this subject tomorrow, and I was having trouble studying, and bumped into this video.
Thanks for making these videos. I have downloaded a lot of your lectures and I have greatly benefited from it. Before now I just watch and learn but now I pause the video when you say and try the workings on my own. God bless you and yours. Much love from Nigeria ❤
Thank you for your even tone of voice. You are very easy to listen to. The only suggestion I would make would be allowing a slightly longer pause in between the problems and the solutions for those who may want to pause the video to work out the problems before you go straight to the answer. Otherwise, I reallllllly appreciate the videos!
GiGi Sunshine that’s why you pause the video 🤦🏻♀️🙄
GiGi Sunshine then pause the video 😂😂
GiGi Sunshine use the pause button :)
I had enough time to pause
Exam tomorrow and when I say I’ve practiced, studied, asked teachers, and etc and still somehow lost and discouraged...this is helping me tremendously. I’m just taking college algebra but it’s a summer course so it’s very fast and the professors don’t teach so thank you! So much easier than I believed
i have an exam in inequalities tomorrow and im binging this shit like my life depends on it. Bless u my man. I wish i had the money to pay for your full versions of classes, atleast that way you'd know the KIND OF live-saving work you do.
I am preparing for JEE and always though that the inequality is very tough but recently my friend suggested me to watch you video and now I'm doing good in inequality.Thank You Sir🙏🙏
I thought when it's a closed circle you use brackets instead of the parentheses next to number???????
I wish you were my teacher.😭😭😭
thank you bcs it helps me to recall my previous lessons way back jhs days. i'm currently reviewing for my entrance exams. thanks mate
your explanations and examples are absolutely fantastic and easy too understand way better than my current precalc professor
i would like to say I LOVE YOU! you have solved my issues
omg i wish my teacher was not so complicated, this helped so much!!!
Math is always difficult, having the wrong teacher, some are very good at math but it doesn't make them good teachers. I am teaching myself at home. I have learned more than when I was being taught.
Than you! You bring hope.
You are amazing! Like your teaching style, it’s very organic!
yes, i am searching youtube for math help and yes the videos from 2006 ARE helping for your information
rebecca E agreed
Haha the advertisement
Ooh, was about to ask if we watched the same add
24:54 your answer is wrong intead of using [ after 2.5 and 5.5 you used ). Thanks for teaching me to pick up on that tho...
Yes u r right thnx
Good catch haha I knew someone would comment that I was about to do so myself
Thank you for posting all your math help! You are saving me so much time and stress!
i never liked studying maths online and i dislike it even today but my this year my maths teacher is terrible , im glad that i found this channel to atleast understand the concepts
Thank you so much, in Ms.Parliment’s class, I barely know what to do! 🙏 Thanks. Your are the man! And I have a test tomorrow about this same standard. Like this comment if you agree!
This video was soo helpful! Thank you for making this vid. I had to learn this by tomorrow in order to get a grade ahead in math. Today I was just told about that too. We are learning the same stuff as last year. You are the best!!!!!
Your channel is worth my subscription!!! Thank you for sharing your knowledge, really appreciate it!
Needed a refresher for Algebra 2 this year, thank you!!
What a great video, thank you so very much, I was completely lost! It's actually an easy task, I don't know why teachers cannot explain it this way :( Thank you again! You saved me!
Thank you man, you really helped me with my algebra 1 homework. :)
DragonixPlayz I took algebra 1 in 8th. I’m going to 9th now.

Hows life
@@hazemmustafa5818 I’m going into sophomore year now
@@MicCheckMemoirs how’s life now?
@@smeebisesportzbebbins6200 I’m in pre calculus cause I took algebra 2 over the summer. My teacher signed me up for calculus AB :)
I wondered over here because I still didn't understand I and I knew you could help and this taught me more in a minute than I learned in a four hour class
I have an exam on this tomorrow and you sir have saved my life. Thank you
Damn it! If only I learned this Earlier!!
At 24:50 I think a mistake was made, it was supposed to be (-infinite, -2.5) U [5.5, +infinite) a square bracket was missing from the inclusive 5.5. Or am I getting this wrong?
Yes, I do think the same, it should be (-infinite, -2.5] U [ 5.5, + infinite).
Thank you so much for your help! My professor is Romanian and she can be very difficult to understand. You have no idea how much you helped me for my quiz today. Thank you!! 😄
i dont know what i would be doing if i hadnt found you. all i can say is am blessed and greatful for you.
Is it normal to kind of get it one minute, then be stumped the next. Then get it again, amd repeat.
THANK you, you helped me a lot
This was so helpful for my calculus review thank you so much feeling like a pro now
This taught me the whole thing in half the time the teachers did..! Thank you for this..!
this helped me soon much in only 3 minutes wow
thank you! life saver
Thank you so much! I honestly wouldn't have got this at all if this video didn't exist! Thank you!!!!
When you are good at teaching and delivering information AND your voice is so relaxing... every one is gonna listen and learn ofc
I'm literally having a mental breakdown bc I can't solve a simple math problem and I did one of these yesterday ejbwdjhfbf
same dude ;-;
Same
same btw this isn’t my account
Im stuck in this lesson on my kumon and im on level H131 rn and im answering it while watching this
As a person who is actually capable of understanding my math teacher, this is honestly better.
What takes me a hour to learn in class takes me five minutes to learn here so thanks!
These classes are the best.
Thank you for all the help. ♡♡♡
i got a semester exam tomorrow and he is saving my life
Mohammad Alzuriqi fucking same
For the problem at 14:05 wouldn’t you switch the signs at the end bc it’s a negative number?
maybe she forgot that
was wondering about this as well
THIS IS THE BEST MATH VIDEO IVE WATCHED IN MY ENTIRE LIFE
I finished the whole 30:43 video and I learned a lot than the online class, thank you
Who's watching this in May 2024
