how can you still be arguing? Its 288. Period. PEMDAS is actually PE(MD)(AS) since multiplication and division as well as addition and subtraction are interchangeable and go from left to right.
This has already been debunked several pages ago, giddy. And it's been corrected again and again and again on many of the pages following. :grin: PEMDAS never says multiplication comes before division, but rather that multiplication and division are on the same order of precedence, as are subtraction and addition. When the operators are on the same ranking of precedence, you perform the leftmost operation first.
those who answered 2 are r****ded and needs to start reading from left to right like everyone else those who answered 2 and are also in IT need to get out of IT for those still non-believers here's how oracle and sybase (database software) handle it oracle: select 48/2*(9+3) from dual 288 sybase: select 48/2*(9+3) from [some table] 288
just wanted to add, my 79 year old grandfather got 288, so those blaming it on "how i learned it ages ago" are full of BS!
In my opinion, the higher up in math you went in college, the more likely you are to get it wrong on first glance. After slogging all the way through calculus 1,2, and 3 in addition to diff eq, you are almost "brainwashed" into needing to address everything around the parenthesis first. I admit to answering the problem wrong on the first pass. I literally looked at it for a half second and clicked on 2 in the poll. I'm with the others in the thread that agree the problem is poorly written.
Thats not true. The reason why multiplication and division are on same level is that you can substitute one for the other: ex: 2/4 = 2 * (1/4) so if you want to you can rewrite above as 48(1/2)(9+3). This has nothing to do with calculus and I have taken all of them including diff eq.
It's a math optical illusion. Since one is forced to deal with the right side of the equation first, such a logic-oriented brain function tries to order the equation, in this case right-to-left. Also, the brain subconsciously favors easier computations over more difficult ones, thus the favoring of 48/24 instead of the 24(12). We all agree that mathematics at this level follows strict rules. In the case when more than one interpretation can be made of an equation, the rule is that one performs the operations from left to right. Pump up your brain!
I wish there's an option to change votes, so that we can see how many people are actually convinced and changed, and who wouldn't. That would be interesting.
You missed my point. Completely. Correct it has nothing literally to do with calculus. However, my math professors would use all kinds of shorthand writing their equations (probably due to laziness). So you had to interpret what they meant. Anyway, I do agree the answer is intended to be 288. I'm saying I understand why folks can make the careless error.
CAN SOMEONE STICKY THIS POST PLEASE?? Hi, can someone please sticky my message please. I have the correct answer. 48÷2(9+3) = ? replace (9+3) with x, you get 48÷2x. You cannot rewrite this as 48÷2Xx, which will result in the answer being 288 because of incorrectly thinking that PEDMAS applies reading from left to right. The Distributive Property overrides PEDMAS which means that 2x has to remain together. 48÷2(12)= 48÷(24)=2 The way the question is written, 48÷2(12) does NOT equal to 48÷2X(12), due to the Distributive Property. Someone please sticky this, because this is in fact the real answer. There are others who have copied and pasted google links or from their calculator which recognizes PEDMAS but not the distributive property.
Distributive property is a method of solving math equation and not a way for the equation to be used.
NOt sure what to say. I would have solved it using the PEMDAS method and I put it in an online calculator at Basic-Mathematics.com and both of "us" came up with 2.
Lol at the excuses. What does it matter? If I say ÷ = : = / = , ( = :grin:, ) = and write 482:grin:9+3, the answer is still 288. And smh at "the higher you get in college, the dumber you are" comment. On a brighter note, it's funny that DD is wrong even in thread like this.
