I think it's a

OpenStudy (mathmale):

Please: understand and follow "PEMDAS." You must do mult. and div. before add'n and subtr.

OpenStudy (aishalicious1):

Parentheses Exponents MULTIPLICATION division addition subtarction

OpenStudy (anonymous):

I know i did PEMDAS i think it's a

OpenStudy (aishalicious1):

No A is addition

OpenStudy (anonymous):

can u check?

OpenStudy (aishalicious1):

I know this I am confident should I explain?

OpenStudy (mathmale):

If there are no parentheses, and no exponents, then do either mult. or div. first. Sorry, but I do not deal in answers (a, b, c, d). Please show your work with and explanation of what you did, and then i'd be happy to give you helpful feedback.

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

@mathmale nvm mathmale

OpenStudy (mathmale):

As you wish.

OpenStudy (aishalicious1):

Like @Mathmale said If there is no Parenthese there is no P in PEMDAS so u go to Exponents but in this particular question there r none so you go to Multiplication which is all the way at the end so then you get C

OpenStudy (xxstudyingstuffxx):

Multiplication/Division is the first order. What is farthest to the left in the equation, multiplication or division?

OpenStudy (anonymous):

okay,thanks! c it is

OpenStudy (aishalicious1):

No wait you get D I made a mistake in typing but since Divison is closer than mutiplication its D

OpenStudy (anonymous):

ok.......

OpenStudy (aishalicious1):

Let me sheck the problem k? I dont want u to fail

OpenStudy (anonymous):

ok

OpenStudy (aishalicious1):

Ok so PEMDAS left to right correct?

OpenStudy (anonymous):

yes

OpenStudy (aishalicious1):

So I already explained Parentheses there are none Exponents again none but here's my mistake Multiplication/Division whatever is farther left

OpenStudy (aishalicious1):

So which is left-er...... right?

OpenStudy (xxstudyingstuffxx):

Was my answer efficient?

OpenStudy (aishalicious1):

@XxStudyingStuffxX

OpenStudy (anonymous):

okay, I think it's d would that be correct?

OpenStudy (mathmale):

pink33: Why not show us how YOU would do this problem? That way you'd get the most relevant feedback.

OpenStudy (aishalicious1):

Am I right @mathmale @XxStudyingStuffxX

OpenStudy (xxstudyingstuffxx):

Yes @pink33

OpenStudy (aishalicious1):

Yes D

OpenStudy (anonymous):

ok

OpenStudy (aishalicious1):

U get how u do it right? Srsly

OpenStudy (xxstudyingstuffxx):

Yeah, your right, @Aishalicious1

OpenStudy (mathmale):

I'd prefer that Pink show her stuff (do the problem here for us to check over).

OpenStudy (aishalicious1):

Yeah but Pink has tons of hw and is confused and just needs a new set of eyes plus as long as she can do it it wont harm her in the long run

OpenStudy (aishalicious1):

U get how u do it right? @pink33

OpenStudy (anonymous):

Thanks Alisha! You were very Helpful

OpenStudy (anonymous):

yes, I would need to do PEMDAS

OpenStudy (aishalicious1):

Its Aisha but close enough

OpenStudy (xxstudyingstuffxx):

Do I get medal?

OpenStudy (xxstudyingstuffxx):

*a medal

OpenStudy (aishalicious1):

Wait does medal increase ur smart score?

OpenStudy (xxstudyingstuffxx):

Yes

OpenStudy (anonymous):

yes

OpenStudy (xxstudyingstuffxx):

Can you give me one?

OpenStudy (anonymous):

Which operation should be performed first according to the order of operations? 44 • 2 – [(5 + 20 • 3) – 12] + 16 ÷ 2 A. 44 • 2 B. 5 + 20 C. 20 • 3 D. 16 ÷ 2

OpenStudy (xxstudyingstuffxx):

Again, it will be brackets or parentheses first. What is farthest to the left?

OpenStudy (anonymous):

5+20

OpenStudy (xxstudyingstuffxx):

You need the full thing, so it would be [(5 + 20 • 3) – 12] . Make sense?

OpenStudy (xxstudyingstuffxx):

First of all, do you know what brackets are used for?

OpenStudy (anonymous):

yes

OpenStudy (aishalicious1):

What are they used for?

OpenStudy (anonymous):

i can't rember

OpenStudy (aishalicious1):

So udk........ Google it

OpenStudy (anonymous):

ok u know wht nevermind

OpenStudy (aishalicious1):

The point is Do u know the answer?

OpenStudy (aishalicious1):

Srsly it is C this time Cuz PEMDAS
