Nice Video

[Bubblenuts100]

OMG YOU ARE ON CNN RIGHT NOW!

[misstake71]

I don't understand how 20-30 is = to -10!!!

[akar991]

@misstake71 its change location of that like that 30-20=10

[BryanDavilaTv2]

@misstake71 you are taking 30 away from 20 not 20 from 30

[TheTongaboy]

the dislikes are all the confused teachers that are jealous

[bluemage100]

kaaaaaaaaaaaaaaahn!

[MrMew124]

[jonjonjon1370]

@danXtheXgoon u seem like a nice person :D

[METALCOOLER117]

[BloodRaven6934]

great vid very helpful im from the u.s.a so i do pemdas but really im just saying great vid becuase i dont really care what the vids about

[piano1996No1]

A simpler way of remembering the order of operations is by using the statement BODMAS, B=brackets O=other D=division M=multiplication A=addition S=subtraction. In other words, one would solve by doing brackets first then anything else then dividing then multiplying then adding the subtracting.

[TwinZeroman505]

ahah im doing this in AVID

[KRISTONGOODEN]

WHAT IF THE BRACKERS IS IN THE MIDDLE

[MrDjMarcello]

@KRISTONGOODEN Still do it first.

[BikinisInEnglandGS]

LOVE HIS HANDWRITING!

[BabiLocks]

what program did you use?

[MrAaroncamaro]

Man you so goooooood

[deadroz]

Which software you r using in this video? I am teacher i also want to deliver lecture in this way. if you share link i would be thankful to u.....

[xEpIcDiNoSaUrSx]

Thx a bunch this is sooo much better than hearing my teacher drown on and on and on and on.....

[redbluffhill1]

I was flipping thru the stations and saw u on the charlie rose show. your vids have inspired me to want to learn math again after years of struggling with it. I'm 43 and when i was coming thru none of my teachers taught the way u do so i just gave up after failing pre algebra. im so glad u decieded to put these vids up, i know your helping a lot of people! :)

[chance8401]

@redbluffhill1 What i think is really awesome is how he teaches more than math, he teaches every thing from astronomy to money, when i need help with anything, he's there to provide.

[juicycoutour1337]

U SAVED MY LIFE I WOULD HAVE GOTTEN AN F ON MY MATH TEST IF U HADNT HELPED ME THANKS X10000000000000000000000000000­0000000000000000000000 ETC...

[chance8401]

Thanks so much.

[XuXKrissyXuX]

Please Excuse My Dear Aunt Sally (PEMDAS)

[MrDjMarcello]

@XuXKrissyXuX It could be PEDMSA. Or PEMDSA. Because it's not always addition, then subtraction. Vice versa.

[NzRooman]

@MrDjMarcello In New Zealand... It's BEDMAS as we say brackets rather than parentheses.

[MrChrispocalypse]

i have to do this shit over summer :(

[amirah21]

Love this,  u r helping me skip stupid math classes so I can actually understand college math when I go back to school and get my bachelors degree

[paulceltics]

guess some people are just haters

[squareboy889]

Wth 3 dislikes what happened ???

[souljahjames]

wat made it a -10 instead of 10

[Poseidon3987]

@souljahjames 20-30 did.

[xXxdeterminationxXx]

thanks you helped alot

[xXxdeterminationxXx]

i wish you were my teacher my teacher stands there for 45mins same some stuff on the board while everyone sleeping and you teach a whole lesson in less the 10mins and i understood everything you could've putted exponents but good video

[naimaaf1]

@mrcreations515, I hate them, and I'm glad their're not around anymore. But good luck looking for them. I don't think they believed edu... I'm here to learn not to debate about politics.

[BrokenClouds89]

This man is a superb math teacher.

[cesarthetrucker]

[DrPoque64]

[jigglejack100]

Im a teacher at lake weir middle and i totaly hate your videos i teach autistic kids and they can do way better math than you can YOU SUCK!!!

[CSU198181]

@jigglejack100, You are not a teacher and simply a poser... I noticed there were no legitimate math related videos on your gay ass gun rights channel? Let us see one of your "Way Better" LOL (F'g kid) video uploads smart ass.

[DrPoque64]

@CSU198181 Actually, we are both teachers. We like guns to keep our kids safe, we keep them in the classroom just incase all hell breaks loose.

[CSU198181]

[jigglejack100]

@CSU198181 gay gun right channel are you one of them bullshit liberal asshole teachers.... go fuck your self! :D

@ViperZion

No, BEDMAS.

[xchainlinkx]

@ViperZion PEMDAS: Please excuse my dear aunt sally =)

[gusman821]

you spelled parenthesis wrong. everything else is good.

[RgMarksman]

i tried: (8+5) x 6 / 2 - 10 x 7

My Answer: -31

Please thumbs up this comment if im correct. Thumbs down if im wrong. im not trying to get the highest rated comment. I just couldnt figure out how to send Khanacademy a message.

[Ktayr]

I wish you were my personal tutor!!

[vhill0563]

Thank you, thank you, thank you!!! I was so confused about this process until I viewed this video. I'm a parent of a 6th grader and his textbook didn't explain it at all. Thanks so much!!!

[naimaaf1]

Thank you soooo much....he is sooo better than my teacher. I wish I dont have to go to her class.

[Mrcreations515]

@naimaaf1 do you have a math nazi?

cause i do...

[RebornAc3]

May Allah/God bless you.

[hiccup112]

er. this finishes, then theres another video saying " More Complicated Order of Operation Example " ...........if im lost in this vid , where will i be in that vid???!?!?? xD

Great Video =]

[1GeorgeJung]

@hiccup112 the guy uses some strange word and im only half through it and waiting for it to load but as long as you do multipucation and division before plus and minus you should be right

[jhcenjoy]

Thank you... :D

[jhcenjoy]

@jhcenjoy :)

[MultiJimbo1234]

what software do you make it into?

[CreepNarrator]

you get the same answer if instead of doing 10 X 4 first you do 4/2 first

[Subaangen]

the sattelite might go to Mars :) ...LOL

[Ormaaj]

The ambiguity only really applies to infix operators. You could get rid of it by just using lambda notation.

[rlewis1946]

@Ormaaj Can you give us an example? (yes I could google this)

Thanks, RL Atlanta, GA USA

[TDBhCorsica]

nice vid for beginners, i remember i used BEDMAS , brackets exponents division/multiplication addition/ subtraction, it is just easier to remember. Appreciate your videos of any kind, keep up the good work.

[bloodalicous]

@TDBhCorsica I think PEDMAS and BEMDAS Are the the same thing. no matter still easy SEE YALL
