[@AdventureBrosForever]

Thanks but the amount of cringe I had to go through to learn this nearly killed me.

[@abdelrahmandaoudi955]

Anthony Buoscio very true

[@hypetrained]

This is the best video of this by far. Thank you so very much, you've made my day

[@hypetrained]

Did you have a kid by the name of Brian Courtade in that class?

[@RoseWoodgames]

these are so helpful. i wish you were my teacher!

[@discoscu1]

you sir are a Math GOD!! i wish you were my teacher

[@TheTonitk]

HI AGAIN!it's toni matthews-bey. i emailed yesterday on where to locate assistance for the quiz solving 3 equations having 3 variables. i mean i've been going for a week, half pack of college ruled paper, and 2 refills of mechanical pencil lead trying to figure out wth have or am i doing wrong. i am literally obsessing at this point. i have to take my accuplacer test for a college in april. it is very important i get this stuff. i have gone over the rules for this thing so many times i could probably teach it to someone else. takes two days for my husband to convince me to move on to something new. well today, i'm like screw it. i'll plug in all the answers of the multiple choice and see which one is the right answer. NONE! NONE SIR! ahhhhhhhh.... i am going completely crazy over here. this will be a great story to cry about with my friends one day. to assure you i am not a complete idiot, i took, for example, "x" "y" and "z" plugged it into the equation x+3y-z=6 and didn't get the answer for all five problems. thanks for listening! your the only one i could officially complain to... lol sincerely,toni matthews

[@TheTonitk]

+Toni Kendall and then i may just be an idiot

[@awakken4709]

so is this an easier way of doing the gauss method?

[@RapPlaylistOnly]

God if anyone is watching these video's cause their fun please just get some friends...

[@RapPlaylistOnly]

Favour John No... No you are not.

[@thefav9997]

What?

[@TheTomboy345]

Is that what your doing, dude?

[@thefav9997]

what ? am confused ???????

[@hailiele2839]

Peter Griffin I watched this with my friend. Top that, bitch

[@ZRabaa]

Dude your making fun of your self lmao 😂

[@mashable8759]

What :O Do teachers like HIM EXIST :O

[@creampuff966]

lol I feel you

[@evam687]

you explained this sooooo much better than my current teacher.. love that you added humour in it, makes the math less stressful haha. you've definitely helped this confused hs student.

[@NathanielValentin]

Me: I learned how to solve 3 by 3 step equations Gamora: What did it cost? Me: A bath full of cringe

[@fish-zb4tg]

Haha, it's very refreshing to cringe when you're stressed. It's quite enjoyable to be honest.

[@calebking6930]

i wish i had a teacher as chill and cool as you

[@shamariking3913]

You are awesome !!!!!!! Why cant more teachers be like you ??!! Lol

[@PinkMeetsVintage]

You legit saved my life. So many people are complaining about the goofing off, but if anything that only helped me understand. I have such a problem with my math teacher because she is as boring as a brick, and not willing to comprehend that its easy to be confused with this stuff. Thank you for personalizing this, and making it easier to understand than my math teacher ever could.

[@crist.9510]

This is an awesome video! You're so fun and this concept is A LOT easier. Thank you!

[@victoriataylor3679]

lol, he looks like a wonderful person....

[@BellezzaBeauty03]

THANK YOU!!

[@taylorsibley1217]

Oh wow! I wish this King was my maths teacher! Maths would actually be so much fun :)

[@theladymisstj490]

Math King is kind of hot. A little goofy but hot nonetheless..

[@RapPlaylistOnly]

What the fuck?

[@johnmiller5171]

I literally just watched this just to see the costume

[@kalandobrown8091]

this guy is a wonderful guy

[@yaymath]

Hi Cristian! Thanks so much for your message. If your school arranges for guest speakers, let your teacher know about it and perhaps I can come visit your school!

[@darthvadorskates]

Haha. The video list summary is the best! So, bold! So, outrageous! So, audacious! Seriously, packs a lot of moxie.... who knew the king could slay math problems with such ease! Thank you for doing this, and your mission to achieve higher standards of mathematical education for everyone by removing the fear and pressure and substituting fun in it's place. I was always fond of math but could never find a teacher that could explain it properly in high school or college, which led me to fail miserably. Thanks to your great sacrifice of time effort and dedication for the sake of others, you have brought back hope for everyone who have otherwise given up, to try again, and succeed. Keep up the good work man! Oh, and if you get bored, you could always go further and do pre-calc and calculus, not that I'm ever going to get that far, but if I did, it would be because of people like you. I shall part now with an excellent quote for which you might appreciate, "If I have seen further than other men, it's because I have stood on the shoulders of giants." - Isaac Newton

[@andrewDaMack]

Dear lord, all that foolishness, just do the damn lesson. Totally lost with all that antics.

[@sexywolfchick1122]

he's making his class enjoyable, so his students don't get bored and loose interest. If there is one thing i hate, its having a teacher with no personality

[@andrewDaMack]

True and I agree but he's doing too much...its distracting.

[@andw3r]

Andrew Oneil me too i just wanted to know how to do it. i dont need all the foolin around

[@micanikko]

I think its good to keep his students awake.

[@juanotip509]

This is a very helpful video. I've been learning this concept recently in Algebra II and my knowledge wasn't all there. Algebra II is also a very intimidating subject for myself. This video helped me understand and prepare for my upcoming test. I really appreciate the effort you took into making this video. Thanks for being so awesome!!

[@yoshilee5341]

Hey great teaching but...... Some of these laughs seem forced to me

[@rackzz9358]

[@stinkybichez]

I am getting married in a month and a half and I would like to invite THE Math King to join us and you can be brother husbands with my future husband. We can join our 3 variables and solve this equation... or something like that. I'm really bad at math.

[@lexsonsamson6099]

yaymath... i like any videos you uploaded here, it helps a lot.... you look so funny but real making me to understand elimination method ... looking for more videos from you................................ thanks Sir

[@melissarodriguez999]

Wow! Amazing teacher. It was very fun and easy for me to understand (1000xs better than how my teacher taught me)

[@shoukatavakolian9362]

I wish our math teacher was like this!!!

[@foREVerXirish]

im doing finite math for my bachelors in game design and how my teachers we trying to bring this back to me wasnt working so well. Not having done this stuff in 10 years really meant that i needed to find other sources. i searched and found these videos. Thank you so much! you brought it all back to me lol

[@masennakonieczny2377]

damn if I had this class I wouldn't beadle to sleep of my hangover

[@luiavalos92]

I thank you once again for uploading these Amazing videos onto KZbin. I have now passed my math 40 class at el Camino college in Compton California with an A. Math 40 is elementary algebra which was said to be the hardest math course for students to pass. Watching your videos definitely helped me pass my class with an A and my instructor came up to me and asked me to be a supplemental coach, that's an on campus part time job . He personally wrote a recommendation letter for me and I nailed the interview which consisted of math problems front and back and I had to present a problem on the board in front of the people who interviewed me. I aced my final and class thank you Mr. Adhoot!!!!!im planning on majoring in aerospace engineering and plan to take more math courses and watch more videos of your masterpiece videos. Thanks man. Sincerely Luis Avalos

[@jamesa.646]

I feel really dumb ,when he was asking questions to the class I was subconsciously responding out loud. BTW thanks you are so spontaneous so watching you never felt boring and I also learned a lot.

[@markkov]

Can this man get to the point, not talking about his damn cat milk..smh

[@theamericanimperialist9362]

I'm enjoying your math videos, thanks.

[@geoffreymwangi6627]

I wish i would turn myself to a boy & join the class.

[@V10Lifts]

yo Thx Bro and 1 more thing Hi BellezzaBeauty

[@bryannguyen2862]

Thank you, Yaymath. You are going to save me from getting a D on my math test on Wednesday. I appreciate a ton!

[@inniss68]

Hey , you re making maths fun ,, cheers

[@zakariagamadid130]

you're good teacher but you're really confusing us you're comedian you spent the whole time with goofing off

[@abdelrahmandaoudi955]

Zakaria Gamadid true

[@cilenetequila]

Hi, how did you get this number (-2) in the equation? -2 (x+2y+z)=10 Thanks

[@tonypaoletta9196]

when you are doing elimination what ever variable you are going to eliminate you have to have one a positive and one a negative for example: 2x-2x=0

[@micanikko]

Now im just watching his vids because its fun. XD

[@keianasimpson2362]

Yay Math! I have been watching you since high school! You make math so fun to learn! You are one of the reasons I my major is Engineering! The part where you showed the 3D axis made me very interested to learn more in depth math. I remember this video from high school. I wish more teachers could be like you. You break every step down to the point where I understand exactly what's going on. Math is a language just like anything else and when you teach your students you break down the terminology. I am now taking Calculus 3 and it has a lot of algebra which has brought me back to your videos. Thank goodness for yaymath!

[@SupraKing2015]

"I will slay her upon her return!" lolol

[@violalole]

You're just so cute. and math with you is FUN.

[@hazeleyezluv]

I like him. He's funny. 😊

[@stef_ii8880]

2018 almost Halloween 👻

[@yaymath]

Thanks so much for reaching out. Could you connect me with your administration?

[@john2975]

he looks like the lead singer of the band breaking benjamin

[@LesTwinsSociety]

From a kid who's struggling in Pre-cal and gets totally lost with Gauss Jordan methods, thank you so much! I learned this method back in Alg 2 with trig and I find it so much easier this way than how my pre-cal teacher does it. It was a bit silly, but I didn't mind it since I usually find math class kind of boring and painful. This was a nice change from how it is in my actual class...thanks again! :)

[@captanblue]

You totally just helped me explain this to my sister. You were a tad goofy but who cares, you did more in 10 minutes than my google searches ever were.

[@poppysgtspanky]

Looks like Oscar Isaac

[@mohamaddahhan6069]

Best Math teacher, I have math exam tomorrow and i know k=nothing now I know everything thank you.

[@Noni888roni27]

I friggin' love these YAY math lessons. I wish I had teachers like yaymath when I was growing up. These lessons are fantastic with a teacher who has patience and a real skill of breaking down the concepts. Thank you for having these and making math learning fun!!

[@joshday2043]

I throw down my math gauntlet, challenging you to a math duel. May the most chivalrous mathematician win.

[@celeste_xo]

why dont u just simply focus on math??? teach alone....students are major distraction..

[@charlesdegracia6568]

says the one with justin biebers face as a profile picture

[@celeste_xo]

charles degracia who cares??/ thats irrelavant

[@shakiestapleton7147]

Why don't you because not everybody wants to listen to all of the background music. Its distracting

[@tonypaoletta9196]

Shakie Stapleton the reason why he has the students in the back ground is because the students ask the questions that other students might have as well or something similar so he is doing it for your benefit also ive seen many videos were the teachers just teach and i dont believe they help as much as he does (my opinion) he spoke on TEDX about this

[@neo6786]

thank you very much Yaymath :)

[@mserebreny]

He is using the elimination method; the object is to multiply the top and/or bottom equation so that the coefficients of one of the variables are reciprocal to each other; ie, one is 2x, the other is -2x, or 3x and -3x, etc. That way when the equations are added together, the coefficients will add to 0 --> -2x + 2x =0, and the variable will be eliminated. Notice after he rewrites those two equations, the X variable no longer exists

[@sheltonclarck1432]

I ENJOY ALL of your vids man keep them coming dude keep up the good work!!!!!!!!!!!!!!!!!!!

[@m4mee1]

thanks YAYMATH for this fun filled tutorial, really appreciate that! it totally helps!

[@anonymousrain6370]

This was very helpful and entertaining. Thank you so much for the support.

[@jada004]

so my teacher gives us equations and he starts us off with the solutions being fractions and i get so confused while im solving the equation and my answer would always be off by like 2 or 3 number. i know the steps but can you please tell me what im doing wrong and i solve the equations using the method that you use in the video your help would be greatly appreciated

[@Gracemystar]

Oh My God. You saved my grade. I have a test tomorrow, and this section was not making ANY sense. I was about to give up all hope until I came across your video. Its late at night and I finally understand! Ahhhh! I'm so happy. You sir, are amazing. Thank you very much for taking the time to make these videos. Much appreciated! :D

[@TheTomboy345]

Thank You YAY MATH!!!! I really appreciate your videos!!!! stay awesome!!!!

[@meli1497]

I loved this! I honestly don't know why people are saying it was bad! It was really helpful! Easy to understand way better than my current teacher, although he is a really goof teacher, he just goes too fast for my liking.

[@SourLikeWorms]

Thank you! You are truely amazing. My math teacher does not know how to teach and refuses to learn how to teach. (Amazingly, it's an honors class too.) Thank you for saving me hours of stress and anger. You are the best!

[@crisjaimescj]

Thank you very much. I was struggling for over an hour and i decided to look for some help on youtube and i found this video. Im very glad i did because i finally solved the problems i was struggling with . =)

[@stephenjones6472]

It's interesting: most textbooks teach "addition" and "multiplication", but, we can subtract the equations, instead of multiplying one of them by negative 1.

[@LolingAtYouxD]

Thank you SO MUCH for posting this. I literally never could have stood through watching this (even though I needed to learn it, I don't like math) if you hadn't been so funny and all. I watched the whole 28 minutes; I can't usually watch 15 of anything else school-related, especially math. So yeah, idk, thanks ^^

[@haleykj13]

I've watched so many videos to try and figure out my homework and nothing helped. But after watching your video I did my homework and finally got the correct answer. Thank you so much! Great video :)

[@entropy7888]

I had a test the next day and was stressing with a stomach ache because I didn’t understand this concept. I was reluctant to watch a KZbin video since I was afraid it would be purely analytical and fail to give explanation. My stomach ache vanished a few minutes into this video. You not only taught me what my teacher failed to teach, but made me feel a whole lot better about math. Thank you, yaymath.

[@minkoo9006]

I loved you, you're super funny. PLUS that ring tone, Bobby V - Slow Down. Ommmg xD I wish you were my math teacher.

[@canelam256]

yaymath, thank you so much, for teaching this problem so well. I have problem with math, but you make it fun. I love you my man. A big hug for you.

[@Teedimps1598]

To tell the truth in class I tried so hard to understand it was way to difficult. But once I got to Yay Math it was a piece of cake, thank you.... I really thank you for saving the day. Now i can do my homework

[@Scoobydcs]

iv completely forgotten algebra and im stuck with 2 questions t= 7s/3+4k 3k-5t=4s(9k=7t) DONT give me the answers but could you please tell me how the hell to find k. its doin my head in because i cant remember a thing lol

[@amostemitopemakinde6634]

Awww this is a very good way to learn math. how I wish my primary school math class was like this then, today I am sure I am going to be one of the best mathematicians in the world. thanks so much, Teacher God bless you.

[@nuitekoha2269]

Oh mah gawd! This honestly saved my life 👌🏽👌🏽👌🏽

[@magdybakir2552]

If it is a multiple choice question can you just substitute the values in the equation and see the pair of values that make the equation true.

[@yamanaripvp8749]

The thing with me in 7th grade is Like. I'm paying attention Im writing all of it down then the teacher gives us a problem after showing it But Even tho he showed us I just cant do it I came up for lunch to do equations i got it then forgot it 2 days after Just i cant get it to stay in my mind

[@bacmoe9280]

You are a such lucky students having kind teacher like him , in Iraq 🇮🇶 math teachers hitting us and slapping us. Just sad 😞 😔 😢

[@Ortega738]

Thanks for the video these problems intimidate me, but im getting more confident, and now I just have to gain confidence using the matrix!

[@macjosephnwobi7726]

I wish I was good at math man. This is my biggest sadness in education math has caused me to have a lower gpa then I deserved, so much stress. Hopefully one day in my life math will come easy.

[@annmcb]

Thank you for this video. Your hard work and simple explanation is appreciated. I will now complete my homework assignment.

[@DivestInnocence]

Very nice, thanks for the help. I'm currently an adult taking Algebra II (humiliating), but these videos help out tremendously.

[@great1128]

Wow!!... u r so great..... i m so happy..... i wish u were my maths teacher😢😢... i love you!!!

[@eliisolorzano]

You have a great personality and you make math not a boaring class. :D You are handsome too, hahaha. Thanks agaaainnnnnn!

[@lenasances5045]

[@djsbro58]

Nice vid man my teacher is confusing as heck and this helps a lot and it’s fun to watch! Will recommend to friends :)

[@jenicadavis4292]

Can you do a video that simplifies radicals involving one variable, such as 2√48n , or -7√x^4?

[@HalifaxHercules]

I figured it out both problems using Gauss-Jordan Elimination, and I got the same answer.
