Order of Arithmetic Operations: PEMDAS

Prof well said.

I thought that you have to do addition then subtraction?
15 + 25 - 54 + 8
15+25=40
54+8=62
40 - 62 = -22
If you're following PEDMAS how did you get -6? You didn't exactly explain

so what about all these videos saying PEMDAS is wrong? (or the other orders like BEDMAS?)

Could you explain me 2nd situation

5-(4-7)+4/2=10

Who’s here for fun?

How 5 ans came in 3rd question can anyone tell ?

Excuse me po, Professor Dave. Why is my answer in Checking Comprehension in no. 4 is different? My answer is 12, while at the screen, shows 26.

Is the slant (/) meaning half ?

We did BIDMAS = Brackets, Indices, Division, Multipilication, Addition, Subtraction 😅

You make difficult topics increribly easy!

can someone please enlighten me why the second comprehension was 10 and not 4?

I gotta say, I love the little groove music during the "Checking Comprehension" segment. Feels like I'm doing a little video game tutorial. Ha ha.

How on earth did you get -6???? Cmon professor please explain!!!

as an new grade 11 student, thank you math jesus.

55
4
3
26

15+25-54+8
=40-62
= -22

in Guyana we use Bodmas

Isn't it BODMAS (Bracket Order Division Multiplication Addition Subtraction)?

💙💙💙

I FUCKING OWE YOU EVERYTHING, STARTING COLLEGE, all those years in school the teachers couldn't teach ME SHIT BUT IT ONLY YTOOK YOU 4 MINUTES TO TEACH ME love YOU!!!!!

Bodmas vs. pemdas

i get it now

The awesome thing is that I actually get where I went wrong on the comprehension questions rather than having my teacher to "Well you didn't use my method". Bro I got the same answer!!!

Here from a stupid internet poll. X = 1 after all.

Thank you prof do you offer one on one online maths and physics lessons?

I thought I understood and then got all the answers wrong 😂 showing us in red how to solve the equations at the end would be beneficial for further clarity 🥲

the first way you used the negative number but with pemdas u ignore the minus sign?

Okay I kind of got it but I'm curious 🙂

If it was used to do addition the subtraction that's wrong it's not -6 it should be -22 tell me if I'm wrong ????

How is it -6 ???????

So if not told otherwise I just have to stick with PEMDAS?

We learned BEDMAS?

On 1.55 the 5.3 seem like five point three. It should be 5(3) in my suggestion.

Thanks for the beautiful session professor Dave!

I know this is 5 whole years later but I’m binging this. Is there an explanation as to why this is the convention that was settled upon? Like why this specific order and not a different one?

how do u get 26 if 14-9 = 5?

Nice!

From university 😅

= 55
= 10
=5
=26

Thanks thats help me a lots

Thank you for your wonderful channel! My son is a great fan! :)

Thank you I’m still a kid I’m 11 years old

Nice vid

Wow I never enjoyed learning math, until now thanks

pemda, pemdas, pemdas oooh

the face at the end of his song is funny🤣🤣🤣 bvvbbbnnnnnmm,,,,,

Nice math bro you really help me allot

what does 4/2 and /9 means?
is that fraction?

wow, got them all right.

I just came here to say two things, 1 why tf is it called pedmas on this Video we all know its bedmas (bracket b) and two thank-you for sharing your knowledge professor
