I'm a self taught sophomore in Algebra II.

Thank you so much for being my teacher for today <3

[jamesedwardtheobald]

The best math teacher I had in Junior High School made math fun, and was, consequently the most popular teacher at the school. All teachers should be so enthusiastic, and learning should be fun, makes the information 'stick' in the brain pan more, and for the young, would tend to stifle mischievous behaviour from anxious students, engaging them, instead...

[alphamale442]

is there a part 2? :(

[yaymath]

@alphamale442 all full length videos can be found on yaymath.org! Thanks for watching...YayMath! YayYOU!

[enthusiastmathkid]

I have a video on solving quadratic equations, both standard and non-standard , ie, one that has no square term but when being transformed, it becomes a quadratic equation.

[tharkrish]

superb..!! so great u r great..!! u make math life so easy..!! Go yay

[Balphagore13]

thats what you called a real proffesor!

[MBJB07]

I can't take you seriously when you're wearing that costume. It's distracting... :(

[infinitesimotel]

I would go back to school if I could be young again and have you as my maths teacher.

[uberguitargeek]

[yaymath]

@souljachick95 YouTube has time restrictions on the videos thats why this is up in 3 parts. If you don't want to click around though check out the yaymath.org website! There you'll find the full length videos and a practice worksheet to go with each lesson. YayMath!

[kcidd12]

@souljachick95 XD

[Mattalicous]

First 1:30 i'm all like is he going to teach us or what?

[lurkingzombies]

Thank-you for posting this, I thought your teaching method is awesome. I don't know but you are like the math whisperer lol! I like listening to you. Thank-you :D:D

-Halifax, N.S.

[crazypandaxox]

U joke around too much how r ppl supposed to learn?!

[grig24x]

stop fucking this is not comedy

[missme123ily]

[JennaDarling87]

This video helped me, I stink at math. I'm watching the full length now from yaymath.org. If I were a 15 year old high school girl in his class I would be in love with him, hell I'm in love with him now.

Thanks for the videos!

[THEAVMANN]

this was useless

[JabbaGurl411]

omg! thank you for your help, you made it less complicated!!

[Ralfyaka]

lol cool ass teacher

[alexiofilms]

He looks like the guy from Signs.

[ovandocarter]

[toffmaranan]

the hell!

[neoflowers1234]

I want you as my teacher!!

[bunnykat1]

This guy is HOT HOT HOT!!!

[mintedsalami]

due, can you just like come here and be my math teacher? xD

[alnbarros]

I seriously wish u were my professor in college. I am in math110 and have a 75 years old math professor. I found your videos, and they are saving me so far.

Thank you so much.

[Arcticsource]

love the stark trek outfit, thanks for making this less confusing for me...charles

[yaymath]

@Arcticsource Thank you! I'm so glad the video is helpful!

[dannydude17]

@Arcticsource OMG lol my teacher says that too! lol every single time. charles...... XDD

[NukeMyHouse]

If I only had a math teacher that wears a Star Trek shirt...

[esca8652]

This is so easy, it looks like College Algebra is going to be pretty easy for the most part.

[instantramen]

1:00 "it's hard". finally, he speaks the truth!!!!! instead of other teachers who lie to you and say its easy lol

[50centgame111]

he looks like he's from star trek

[ps3istheshit2]

I used to have fun teachers like this

Then I graduated :(******

[qwertyfshag]

i wish my math teacher was as cool as you. my math teacher is a cranky old hag that smokes 2 packs a day

[SpoiledLogic]

omg this video sucks so bad. I just watched this exact same problem over at the Khan Academy and he explained the derivation of the vertex formula, which gives you an intuition about how quadratic functions look like. Not just mindlessly pluging in a, b, and c as is shown here. OMG this sucks.

He doesn't deserve to be a Starfleet Officer!

[avnguyen123]

his left nipple can control the volume of the class!

[nsd1009]

La clase es muy buena, aunque al principio no me gusto, el nivel y la dinámica usado frente al grupo me encantó, excelente.

[onethingsailing]

You are a good teacher. Don't listen to the negatives. Love the humor and it's all about the kids.

[chiefjustice69]

I wanted math, not failed nerd jokes

[D0z31]

gotta make up a 53 in 1 week! xP

[tonyyfighter]

You fucking bitch asses. This is the biggest scam ever! Oh and 1 your shirt is gay. 2 your class is retarded. 3 your retarded

[UnDaCuVaHkILLa17]

retard 1:13 1:30

tu tuh rahh

[MrCrzymich]

WOw immature hoes in the background.

[Lawtsy15]

Helped a lot thanks!

[88pie88]

star trek shirt.

[punjabijatt987]

the class is fuckin annoying

[HDMix]

THAAAAAAAAAAAANKS!!!!

[Joeki11a]

Is he from STAR TREK???

[indegruv]

I love these videos, what a great math teacher. ++++++++++

[xoxomichee]

You're awesome! Your videos help SO MUCH and I'm in college. Lol.

[pitbull416]

i rather this guy than my old teacher that doesn't even use the white board. never ever does=[

[thevideovlogger]

Im 13 and these are very difficult but i asked my teacher all the time how to i find the vertex how do i find this how do i find this and i got it after just a day of all that it is not difficult at all but when an asshole like this guy just screws around you dont learn much at all hes like playing with his tit at the beginning like what the fuck

[AnderJ017]

@thevideovlogger I LOL'd and yeah, true.

[jperez0341]

Why dont you stop acting like a fucking fool and teach these kids. They are there to learn not to be entertained. You are wasting their time. Idiots like you are why our country is behind in education. Of course you'll say "learning should be fun" no asshole learning is important. I couldn't learn to wipe my ass from you and your silly fucking ass. Go to hell

[AmandaPandaaaaaa]

That's funny, because I actually learn like this.

Whenever a teacher just gets up and drones on about cold hard facts, they lose me.

Maybe the reason our country's behind on education is because we don't offer to teach in the way children need to be taught, but in the way we believe they should be taught.

[warfrek93]

@jperez0341 It beats the hell out of listening to a monotoned teacher, this guy's great

[bosk128]

Then why wwatch his videos if you don't like them you arrogant little infant? If you don't like the way the guy teaches then simply don't atch his videos instead of coming here and complaining and making comments that no one agrees with.

[poohfan2]

Math is serious..Stop playing jack-ass

[ANBU181]

I think he is gay...

[indegruv]

I think YOU are gay.

[ANBU181]

*Cough*

You don't even know who you're talking to man. First of all, I'm a swimmer and am quite "tank". Second, I am in the IB Program with a +90 average, so don't underestimate my intelligence either. I missed several math lessons because of swimming, which is why I watched this video in the first place. Don't be prejudice towards people who watch manga (I actually don't watch it anymore; this is an old Youtube account) because you don't know shit about them.

[indegruv]

replied to wrong comment, obviously. But whatever, I'm sure you're so awesome and shit you could figure that much out without blowing your own horn.

"peace"

[Ihatenicknames1]

@ANBU181 I am in the IB too ^.^

and +90 wow o_O you do SL math?

[ANBU181]

@Ihatenicknames1

Yeah. My school doesn't offer HL math.

[Salooon101]

you suck, mr Dude. Though his teaching is good.

[mattiasrydgren]

i'm only 15, and we are learning this XD

lol

he seems to be verry nice!

(how old are the students??)

[dkrhymes]

The teacher seems to be very nice but I think he should of finished the video. I'm studying for my final and i cannot afford to waist minutes like this, they add up.

Please, next time dont leave us hanging like this.

[maksusername]

@dkrhymes

I agree with you in every way. But I just think it's hilarious. You just wasted minutes typing that...

[MrYusuf99]

it would be better if there was no class =/

[UnDaCuVaHkILLa17]

@MrYusuf99 

[pcnerd1010]

OMG thank you so much, I missed a week of school and I really needed something like this to help me review so I can catch up...Thanks! =D

[amu512]

that was a waste of 6:23 minutes of my life. seriously.

[DardanEm]

@amu512 Why did you watch it then...

[afrikan57]

@amu512 ::Then why did you choose to watch for more than 1:00 minute?

[JJOSH5]

omg this sucks.. no offense.. This is like grd 10 and your class is real stupid.

[MayRy4n]

you just said your class is real stupid? how about not being a dick and making a dumbass out of yourself commenting negatively and incorrectly on a video from a nice guy, just trying to help people like you and me learn math. YAYENGLISH BITCH

[amir2287]

MAAAN I wish this guy was my teacher! Your awesome, and great teaching to.

[Alice260265]

This teacher is Excellent!

[furuzon12]

[makunah]

[kingkilla140]

[DWNSPRKS]

This guy is awesome! I'm using all his videos for year end review. Way better then looking through my chicken scratch notes. You've been a great help, thanks a lot!

[PengoTango]

[SOthrillicious1984]

Thanks so much! this video was alot more useful than my dutch math teacher at school. She shouts at us.This made it much more understandable and fun!

thanks so much!

[worldfamousfishdance]

At least you guys arn't graphing creamy equations... omg that was an awesome class

[weropituco]

how do i expres the valor of the vertex on the graphic with that points, i know it is quadratic but were are those points like the division of -2 betwen 2a on the graphic do they are really exist or they are only a reference
