Algebra - Solving Inequalities
Вставка
- Опубліковано 3 лис 2016
- There is a now-famous rule about switching the inequality sign whenever multiplying or dividing both sides by a negative. But why? In another special video of Yay Math in Studio, we go over the rule, then apply it to solve several inequalities. The number line comes up too, so we explore that.
Then, we go over some expressions that come up in word problems, such as what "at least, at most, no more than" and "no less than" mean with inequality signs. YAY MATH!

Im honestly astonished on how simple my math teachers could've taught inequalities
Sameee 😂
I know im asking the wrong place but does someone know of a way to log back into an instagram account??
I was stupid forgot my password. I would love any tricks you can give me

I love everything about him
the internet is amazing!
yay!!!!!
You are funny ...best of all, easy to understand math with you. I wish you were my math teacher!
Wow multiplying by (-1) really demonstrates the reason why we have to flip the sign, thank you sir!
Jackington Kellogers it’s not that it’s (-1) but because it’s negative don’t think about the number but think about if you are multiplying or dividing it by a negative
I have to say, actually explaining why a function works a certain way instead of forced memorization works so much better to learn a topic👍
It’s sad that we come back to videos like these on UA-cam. And ppl wonder why teachers don’t get paid much. But I hope he does Bc he’s awesome!!!!
I wish you had been my maths teacher. You are crystal clear in your explanations. Have a day and please continue to make these videos.
u make things so much clearer💯®☝
honestly, I've never had so much fun learning about inequalities. Seriously though, great content and even better tuition. Good job!
Graham: thank you. It's an honor to be in your corner during your learning journey.
I love that last thing you said about how we're all in the same boat trying to make sense
I love your logical explanation! This is a great video... I think we've watched this at least four times. Yay Math!!!
Thank you! I'm trying to go after my GED and Math is all that I have left to achieve. This helped! Thank you!
Yaymath u are saving me from despair and hopefully my GPA as well!!
Loving your teaching skills
Hello willowtree , What class are you in?
Did he just say Whatup? That was the best way to start a video, no wonder I replayed twice. He is so entertaining to watch yet he gets to the point. I wish you were my teacher! You are so funny & you teach very well. Also, wouldn't at least mean less because how can you guess you have more than what you think you have rather than underestimating, @yaymath?
At least means at the minimum or not less than. I guess you know what "minimum" means don't you?
Why would a math teacher be less likely to say whatup? You know intellectuals are actually human, right? He's not a robot.
Thank you so much, you helped me understand this so much easier than other videos. You are also a good entertainer as a teacher. You are a great help.
Super helpful. *loudly exclaims* “GONE” my favorite part 😂!
awesome wish he was my teacher
Same bro

He knows how to teach.
Y'all are so kind.
Me too
Can a number be greater than itself?
Yes, it's a bloke's mental state called "A Legend in his own mind"
If u where my teacher Id Be SO HAPPY TO come to UR CLASS EVERY SINGLE DAY OMG THIS IS HOw Kids Will Learn MAth U have to have the right teacher OML We Need Ppl Like u in math classes
13:06 I love this guy
I just passed my math test for the GED today. Your videos really helped me achieve the math. Thank you and God bless you.
What a huge honor it is to be in your corner. Congratulations on this huge milestone in your life.
@@yaymath thank u so much boss man. U make math interesting while cracking jokes. Its a nice intermission lol. Stay blessed big bro and thanks again!
I'm trying to pass the GED math myself man. Wish me luck. 😁
@@camrynpope1819 for all that i studied, i feel like i was given kitty queations. But hey, I'll take it. Just study hard and the questions will turn to kitty questions. I hopeu get it. Please let us know how u did.
@@iamlazarow3526 Thanks for the advice. I will definitely let you guys know 😁
i love this teacher
6yes
This guy is the best teacher ever !!!!
If there were a few hundred million of you every single student will be so much happier
another great math teacher found on youtube! tysm.
you're so kind.
Beautiful multiplication by -1. Easy to understand the rule. Thank you.
Finally a energetic math teacher
youre literally amazing thank you
A great introduction to this topic and I love your sense of humour. Many thanks.
Thanks for the video
I was getting frustrated with my math HW, but know i feel really comfortable with it.
Thank you so very much. I watch a lot of your tutorials. I see a lot clearer mathematically
I'm from SA 🇸🇦🇸🇦🇸🇦I love your explain 🥰❤️....continues
I wish we got teachers like you in our schools :D
i believe that is a alligator sir.
Let me correct your sentence, just because I'm a Grammar Nazi.
Correction: I believe that is an alligator, sir.
@ACHO Jesus is God. There is a trinity: The Father, the Son, and the Holy Spirit and they are all identified as God. I can argue that and win it with evidence from the Bible.
@ACHO I have so many verses that prove that you're wrong, not just John 1:1.
John 1:1
John 3:16
Colossians 2:9
John 8:58
John 10:30
John 5:17-18
John 14:6 (He created life, and he is life.)
1 John 5:7
1 Timothy 3:16
Not only did He claim to be God, but He also claimed to have the power of God. He said He has the authority to judge the nations (Matthew 25:31-46). He claims the authority to raise people from the dead (John 5:25-29) and to forgive sins (Mark 2:5-7)-things only God can do (I Samuel 2:6; Isaiah 43:25).
Now, where is your proof that Jesus isn't God?
And, a math video went into a discussion about a cult....hahahahaa
You say “burn through these” but inactuallr need someone to break it down slowly. I’m having such a hard time, and I cannot get into college without this class.
I would have loved a math teacher like that
It's sad that I can find better math and science teachers on UA-cam than in the colleges and universities that I graduated from. But at least they're more beneficial to all who are interested in the pursuit of higher learning.
we GOT you.
This is my favorite tutorial.
Thank you Robert.
your amazing love the teachings
Thank-you your explanations really helped me understand better! I'm gonna say something random now, you sorta look like my dad and I'm a little freaked out lol
A good teacher=Happy learning students
Thanks Yaymath!

Hats Off Sir...!!
U made this stuff a lot more than just simple
very helpful for my maths test in 2 hours thx you
i went into inequalities very confused but this has helped alot thanks. Just need to pass my Math GED Test and ill finally get my GED. Thanks alot sir.
You will. It’s inevitable.
yaymath passes my math GED test. Got my GED thank you wouldn’t of been possible without many of your math videos.
This is far too easy and clear to be math! thanks.
Best way to explain it outstanding!
I’m so happy you understand so clearly.
Hi Sir. How would you work out an inequality that has two inequality signs? For example: 2x-5>3+5x
Hey yaymath I have question for you .Is there another way to solve LCD inequalities in short way?I got headche on it.
Love yay math!!
This guy is the best
you are awesome unlike my teacher i can actually understand you
Thank you so much man 😭😭
Thank you sir, good stuff.
Thank you so much I missed my math lesson for today and I had homework and I was completely lost
yo thanks for the video i understand it now thk so much again
your are a great teacher
Thankyou so much 💙
Thank you!!!
thank you so much!, you are very helpful, I wish you were my teacher
You are number one, I wish you could tutor me? Mr. Robert I watched your online classes before I had my GED and now I'm in my second semester in College. I really need help, my math teacher is all over the place sir, she flies through the materiel! Please help me sir?
Thank you !
Oh i got 49 out of 50 because of this video thanks
sheetal shetty s I like your lies
thank you so much *brother*
Excellent ! ❤👍
He is great! No, in real life, you probably will not use !0% of this in real life (unless you go into some discipline that calls for it), but what it really teaches you is how to reason things out.
U are absolutely awesome
Brilliant !
You are a legend

Yay math yay math yay math thank you!!!!!!💥✔✔✔
great video!
This really helped me thankyou
i like people that are interactive and this video was great
Really good video and explanation👌🏻
Wow you're actually a fun teacher
You are the Bob Ross of math
in an inequation like 1/1-2x > 1/2x+3, why can't I just raise both sides to -1 so I can get 1-2x > 2x+3 ??
thank you so much
I love your video, it really funny kim
This is embarrassing but I'm a grade 12 student who never really understood the whole sign switch assignment. I think i get it I'm not sure yet I'll have to do some questions myself BUT I do have a doubt, For trying to balance out fractions can we take LCM of both sides?
I learned so much thanks 😢😭
You are awesome!
You are too.
Who watching in 2019
im watching in 2020
no, 2020
vers. Me too
There might or might not be a pandemic next year

thanks this is helping me
You those seems much easier, thank you
I wish that you were my teacher,thank you soooo much
thank you kind sir
I dont understand, when he multiplyed 4 to both sides of the fraction, why did it become a 2, on the fraction to the right? And couldnt you just make the fractions have a common denominator and then solve?
It became a 2 because 4 divided by 2 is 2. Even if you made the denominator the same (like 4) you will still get 2x - 6 > 2x-6 which cannot be solved
Waooo excellently explained 😳🌹
your the best
13:00 Me: Larger! Him Literally a second later: Correct! Me: ._.
Thanks
He's awesome 👍
May God bestow showers of blessings upon you....
Is this actually going to need in life other than passing tests
If you have a job that requires you to think rather than simply move you body, whatever that job is, understanding how to think systematically is always beneficial. Likewise if you go into any natural science or engineering, then algebra itself will even be directly relevant to your work.
SOoOoOoOoOOoOoOoOoOoOoOoOoOOOOOoOOOOOOoOooo goooddddd wishh u were mah teacher in 6th grade and cant get inequalities but now can thanks
you are flippin hilarious !
