I Need Help Solving This Math Problem

[The Duke]

How's that and I'm still confused how people are getting 11. I get 5 if we're not doing PEMDAS but I'm not sure where the 11 is coming from. Then again I was in special education so I held my own but I'm not as advanced as most of you on here.

MDAS

3x3-3÷3+3

Oh, it's 11.

3x3=9
3/3=1
9+3=12
12-1=11

 

[The Duke]

PEMDAS is Parentheses, Multiplication, Division, Addition and Subtraction in that order. The only one I forgot is what the E is supposed to stand for.

Probably exponents.

This is what ChatGPT says


To solve the expression 3÷3×3+3, we follow the order of operations, often abbreviated as PEMDAS/BODMAS (Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right)).

1. First, perform the division and multiplication from left to right:
   3÷3×3=1×3=3
2. Next, perform the addition:
   3+3=6

Therefore, the value of the expression 3÷3×3+3 is 6.

So is it five or eleven guys? I'm confused.

5 is what I get.

Oh, it's 11.

3x3=9
3/3=1
9+3=12
12-1=11

You did subtraction before division though.

Probably exponents.

Yeah, that's it.

6 makes a whole lot more sense but my brain hurts from all of that writing. I'm just going to see what I get from watching MisterBeale's video.

No. 3/3=1, that is done right after multiplication.

Everything was done in the proper order. I spelled it all out.

Yes, but it's 3x3-3÷3+3

 

[Natural Citizen]

I do believe that we're supposed to use PEMDAS here but I'm not sure how to get the final answer. It's:

3x3-3÷3+3

You have to write the equation like this...

(3 × 3) - (3 ÷ 3) + 3

So then simplified it's (9 - 1) + 3

Which equals 8 + 3

That sum equals 11

Which a lot of people already said.

This makes a whole lot more sense and I wouldn't get five using this system.

Oh oops, my mistake you're right.

You have to write the equation like this...

(3 × 3) - (3 ÷ 3) + 3

So then simplified it's (9 - 1) + 3

That equals 11

Which a lot of people already said.

Oh yeah!! That's right if there's no parentheses you're supposed to add them.

Order of Operations Definition​

As we discussed above Order of operations can be defined as, a set of basic rules of precedence we use while solving any mathematical expression, involving multiple operations. When a subexpression appears between two operators, the operator that comes first according to the list given below should be applied first. The order of operations, rules are expressed here:

• Brackets ( ), { }, [ ]
• Exponents
• Division (÷) and Multiplication (×)
• Addition (+) and Subtraction (-)

The above-mentioned set of rules always varies according to the respective given mathematical expressions.

**division goes first in the OP example (3x3-3÷3+3) = ((9) - (1)) + (3) = (8) + (3) = 11
Based on the Order of Operations, addition and subtraction are of equal importance. We must subtract first because the operation of subtraction comes before addition when viewed from left to right. The last step is to add because there is no other operations left.

I don't ever remember subtracting before adding in PEMDAS though.

You're not supposed to.

 

[Ava]

So is it five or eleven guys? I'm confused.

5 is what I get.

I get 3.

I figured my answer of 5 was so easy it had to be wrong. LOL

 

[Road Runner]

You're not supposed to.

I thought so so why was leftwinger saying that we were supposed to subtract first?

 

[Road Runner]

5 is what I get.

I figured my answer of 5 was so easy it had to be wrong. LOL

I thought that everybody was going to know the right answer right off the bat but I've seen quite a few different answers on here but I do believe that the correct answer now is 11 after seeing The Duke break it down.

 

[lg325]

If you were a book keeper which system would you use?
I still say 5 is the correct answer by the way the problem is setup with out parentheses.

What do you mean by that?
