Read the OP. It does not say 48÷2*(9+3), which would of course evaluate to 288. It very explicitly says 48÷2(9+3). Order of operations is a matter of notation, and the use of a different notation for multiplication (juxtaposition across a parenthesis, instead of a 'times' sign) allows for a different order of operations. Indeed, it is common to interpret 2(9+3) or 2x as an inseparable block which takes precedence over division, even though multiplication by 'times' sign does not. Of course, problems of this nature only arise if you're working in the primitive world of division signs... | ||

Having 2 terms written directly next to each other does nothing but leave the * out. So 2*(9+3) = 2(9+3) The only reason you think that the 2 should be muliplied with each number in the bracket individually is because usually it's something like (9x+3) in typical math questions in which case you would have to multiply 2 with each individually to solve the bracket. In this case however, you can solve the brackets by just adding the two numbers together, which removes the brackets, making it 48/2*12. You could also write it like this (48)/(2)*(12) if you want your brackets. Still 288, no argument necessary here. http://www.wolframalpha.com/input/?i=48/2(9+3) http://www.google.de/#hl=de&source=hp&q=48/2(9+3)&aq=f&aqi=&aql=&oq=&fp=a175e2da902f2e1b | ||

But it isn't it is 48 / 2(9+3) expanding the brackets with the implied muliply takes precedence the B in BODMAS stands for brackets To get 288 it would be better written (48/2) X (9+3) brackets (24) X (12) therefore 288 There is a degree of ambiguity to it. It would be better if it could be draw more like 48 OVER 2 X (9+3) with a big line 48 OVER 24 then (9+3) next to it BTW what does the O in BODMAS stand for? | ||

Everyone knows constants are boring. Reminds me of a joke from studies. When they asked a CS guy in the first year of uni how much is 2+2, he answered immediately. Student in the second year typed it into a calculator and answered. Student in the third year wrote a program in C to get the answer. Student in the 4th year wrote whole OS designed to solve problems like that and at the end asked : What was the question ? And the student just before final exams angrily shouted : how should I remember all those stupid constants. I'd love to see you prove that the answer to 2+2 is 4. IIRC, it took Russell 300+ pages to prove that 1+1 was 2. | ||

I will always read it as 288 but I will accept the answer 2 since the way OP posted the equation is flaw(It's not really flaw but I'm really conflicted as to how people keep arguing it's 2) but I'm willing to accept the answer 2. | ||
