It's 1/2. It's never about old or new interpretaion of PEMDAS. The parenthesis MUST remain intact after performing the operation on whatever is inside it. You downgraded it to Multiplication which is a no-no, i.e. = 6÷3(4) = 6÷12 as parenthesis comes first. Algebraically, a(b+c) = ab + ac always, regardless of what is in front. Math is an exact international language interpreted the same way in every country. It does not change with time and has no ambivalence. Your posting can be very damaging to Math learners.
this is how I see it too. And there really is not any other way. Parenthesis still remain after the addition 1+3 .. only way to get rid of parenthesis is doing the multiplication 3(4), generating the 12 under the devicion mark. So, parenthesis all the way first!
One cannot arbitrarily place a multiplication symbol between the 3 and the left parentheses. It is understood that 3 is a “FACTOR” of each of the numbers inside. For what other reason would the 3 be written outside the () without a multiplication symbol?
6 : (1 + 3) = 6 : 3x4 = 6 : 12 = 1:2 Los factores de un producto, NO SE PUEDEN SEPARAR. Expliquen esto: Si 6 : 3x4 = 2x4 = 8, siendo 3x4 igual que 4x3, 6 : 4x3, también debe ser 8. Compruébenlo.
There should not be any argument because of the implied operator only operates on the parentheses, meaning the 3 cannot be separated from the parentheses, its one term and must be simplified. It’s not 6/3*(1 + 3) which would be a fixed operator, meaning the 3 does not operate on the parentheses. Writing equations has rules just like solving equations. And give up on PEMDAS, it’s long overdue to throw it out because it is flawed in too many way to count!
Nope! 3(1+3) is implied multiplication! You cannot magically change the symbology to explicit multiplication after doing the addition. The rule for implied multiplication changes the precedence such that after work inside the parentheses is done then the multiplication that is implied is done. Casio's website gives a good explanation of the rule. If you write the original problem using explicit multiplication, 3*(1+3), then you would get the answer you are presenting. The underlying reason for all this has to do with how computer algorithms and hardware have to parse input lines. I will add a caution to math students when using calculators to work problems such as this: not all calculator manufacturers have incorporated the implied multiplication rule. TI, for example has not. Some computer software, like Matlab and Maxima, will give a syntax error if the user tries implied multiplication notation.

Distance traveled divided by circumference is equal to revolutions regardless of which formula for circumference you choose.
D÷2πr≡D÷(2πr)≡D÷[πd]
So
6÷3(1+3)≡6÷[3×(1+3)]=
6÷12=1/2
6 ÷3 (1 + 3) = (2)(4)= 8

The answer is 1/2. If 97% failed this then I start to believe we didn’t get to the moon!…😂
Answer is 8(b).
@@RamDas-eo3ol Hi you right I must have mistaken with another answer, (brackets first and time the previous 8)
Somebody got bumped off before it lifted off!

3 it can be a factor as well because the brackets are always first. Last minute too scared to join the club, cheers 🙂

Brackets got precedence,
always in any form. 1/2. Last minute scared to join the club before take off. 😊Cheers
You might have me drive the rocket ship so we can get back.

The answer is by which is 8 ie 1+3=4
6÷3=2 therefore 4*2=8

B 8
Brackets are first 1+3=4. Always left to right. 6÷3=2. 2×4=8. Pretty basic math.
2@4=8
b)8
I think its 8
6 :3 ( 4 ) = 2(4) = 8 ( b )
6 ÷ 3 ( 1 + 3) =?
6÷ 3 x 4 =?
2 x 4 = 8
Who is Brian Logic? Maybe he is a guy who follows PEMDAS to solve math?
3 isn't a factor here.
Answer is 8 . Not 1/2 .

Si 6:3x4 = 8, 6:4x3, también debe dar 8. Pero no.... Porque el método empleado, es erróneo.

The answer is 1/2 because parenthesis has presidency. ( 3×1 + 3x3) r= 12
It´s 1/2, I guarantee it!

Nope. They are rules. Arbitrary, perhaps, but the rules nonetheless. As such the answer is 8
