NinjaNick Posted April 12, 2011 Report Share Posted April 12, 2011 That answer would definitely be expected from you. See Nick, Cattani sides with you, thus you're wrong. Ouch! so now we have screen shots of the exact same calculators with different answers. This is how religions get started. Quote Link to comment Share on other sites More sharing options...

It's not that they're more accurate -- it's that TI changed the logic.http://epsstore.ti.com/OA_HTML/csksxvm.jsp?nSetId=103110Nobody is right because there is no agreed consensus on whether implied vs explicit multiplication takes precedence. http://knowyourmeme.com/memes/48293 Edited April 12, 2011 by JRMMiii Quote Link to comment Share on other sites More sharing options...

Hence the updating of the logic. In this instance it doesn't matter. 48÷2(9+3)= only has one instance of multiplication, and that's 24x12. But with what you posted, "Implied and explicit multiplication is given the same priority." Quote Link to comment Share on other sites More sharing options...
chevysoldier Posted April 12, 2011 Report Share Posted April 12, 2011 Multiplication and division are equal, you go left to right after you do the parenthesis. It's 288!I asked my old math teacher and she at first said 2 then caught herself and said it's 288.288.288.288.288.288.288. Quote Link to comment Share on other sites More sharing options...

Interesting. So Multiplication and Division precedence is just wrong but the precedence of implied multiplication is still debatable. Either way, calculators updating their logic and the fact that the standard order of operations give the answer 288 says to me that the agreed on standard is 288 and ultimately in math the most important thing is that we all agree on the same rules otherwise spacecraft will fall from the sky.

Scruit Posted April 12, 2011 Report Share Posted April 12, 2011 Excel says 288 so I'm sticking with that. Quote Link to comment Share on other sites More sharing options...
Bad324 Posted April 12, 2011 Report Share Posted April 12, 2011 the first time i did it I thought it was 288then I looked and see how it could be 2. I asked my math teacher friend and he said 288 so if I'm wrong I'm blaming one of the top public high schools in the state Quote Link to comment Share on other sites More sharing options...
Disclaimer Posted April 12, 2011 Report Share Posted April 12, 2011 But with what you posted, "Implied and explicit multiplication is given the same priority."Right -- but is that correct? http://mathforum.org/library/drmath/view/52582.html5. There is still some development in this area, as we frequently hear from students and teachers confused by texts that either teach or imply that implicit multiplication (2x) takes precedence over explicit multiplication and division (2*x, 2/x) in expressions such as a/2b, which they would take as a/(2b), contrary to the generally accepted rules. The idea of adding new rules like this implies that the conventions are not yet completely stable; the situation is not all that different from the 1600s.In summary, I would say that the rules actually fall into two categories: the natural rules (such as precedence of exponential over multiplicative over additive operations, and the meaning of parentheses), and the artificial rules (left-to-right evaluation, equal precedence for multiplication and division, and so on). The former were present from the beginning of the notation, and probably existed already, though in a somewhat different form, in the geometric and verbal modes of expression that preceded algebraic symbolism. The latter, not having any absolute reason for their acceptance, have had to be gradually agreed upon through usage, and continue to evolve.As a coworker pointed out since his whole job is to fend off ambiguous questions all day long -- "the real idiots are the ones that answer without asking for clarification or don't realize you're allowed to say 'I don't know' when presented with a vague problem like that."

scottie.harris Posted April 12, 2011 Report Share Posted April 12, 2011 ok seriously, its not 288. ive been in school for engineering for 3.5 years and have been through several advanced math classes. According to pemdas (parenthesis, exponents, multiply, divide, add, subtract) thats the order in which you are supposed to do the math. so there for you start with whats in the parenthesis which is (9+3) which equals 12. now you have 48/2(12), a number outside of parenthesis without anything in between means that you multiply so that is 2(12) which is 24. you are left with 48/24 which is 2.BTW to those who used a calculator, they are not always correct ask any teacher or professor. there are several operations that they are not able to do.

shadyone Posted April 12, 2011 Report Share Posted April 12, 2011 as an engineering student i looked at the problem and in my head got 2.now i got 2 because i was taught that distributive multiplication comes before regular multiplication and division there for i did (9+3) then distributed the 2 -- 2(12)=24 then did 48/24. ..= 2EDIT FOR CLARIFICATION:i did not change the problem and got 2..

fizzer Posted April 12, 2011 Report Share Posted April 12, 2011 We can all agree it simplifies to 48÷2*12, and from that point anyone who does the division first must read from right to left, much like a terrorist might(since multiplication and division are equal). Anyone who answers 2 is now in the TSDB(terrorist screening database). 288 FTW! Quote Link to comment Share on other sites More sharing options...
