48÷2(9+3) = ???

The power of the parenthesis

Like homie said last page (and others within this thread) it's a poorly written problem.

we know how youre getting 2 and we just happen to disagree, distribution is a product of pemdas... PEMD>AS

48 + 2(9+3) ... distribute
48 - 2(9+3) ... distribute

48 ÷ 2(9+3) ... dont distribute... follow order of operations

actually you follow the order of operations in all three examples.

in examples 1 and 2, you do inside parenthesis first, then multiply (notice i didn't say distribute, as you add the numbers in the parenthesis before multiplying), then add/subtract

example 3 has been explained ad naseum, but all 3 examples follow the order of operations...not sure what your argument is here.

youre misunderstanding me, distribution is a product of order-of-operations, but people are treating it like its its own rule, its not

what you call "order-of-operations" is the same thing as distribution in those first two cases

because its the SAME thing

2(7-3)2

solve that with your interpretation of "parentheses" in PEMDAS

youre, the one thats manipulating the problem, giving special preference to that 2 thats outside the parentheses when there shouldnt be

would love to see an answer and explanation to this problem by the 2 crew...

if the 2 is included with the parentheses, it should be multiplied to the 4 before the exponent is done correct?

youre NOT understanding me, in those first two cases, "distribution" and "order of operations" are the same thing

because distribution just happens to apply to those first two cases (addition and subtraction), people seem to think it applies to the third case (division) BUT it doesnt, thats how theyre winding up with 2 as the answer

yeah, i don't understand what you're saying...but after re-reading your post i see you're team 288, which is what matters here anyway.

the same way you say that i assume because i added another set of parenthesis, i say you're assuming by adding parenthesis to make it (48÷2)(9+3).
my point is: there is a division sign, not a /. when you change it from  ÷ to a / you open up a venue for misinterpretation(whether its 48/2 times (9+3) or if it is 48 divided by 2(9+3) ), which in my opinion, is where the 288 believers have been led astray.
THE DIVISION SYMBOL DOES NOT SEPERATE FRACTIONS. Only a horizontal line indicates a fraction. Im not adding a parenthesis because its not needed if you go by order of operations you will get the answer. You cant find any evidence of the division symbol indicating a complete fraction for an equation. Im giving you the opportunity now to find proof of your belief. Obviously if you cant find proof your belief is false.

The irony of your screenname.

You're doing a little too much work.
