‎48÷2(9+3) = 48÷2(12)
48÷24= 2

Lol... Toppa yuh bring dis here now?

My answer is still 288.

BODMAS (or even BOMDAS) says you solve the brackets first (yielding 12). That much everybody could agree on. There are no exponents to consdider so next we move to the the "DM" part. Multiplication and Division (and Addition and Subtraction) are operations which occur at the same level of priority, so you can do either first... the only thing that the rules specify is that you evaluate them left to right.

There for you ought to do 48÷2 before you do 2(12). 24x12= 288.

Actually is 288 I did get yes. Ah gremlin did put ah extra 12 number in de calculator.

The disagreement between the "2" and "288" camp centering on the priority of operation between multiplication and division. Some insist that yuh must perform any multiplication first. Others like me say there is no order of priority, and none of the old mnemonic rules (BODMAS, BOMDAS, PEMDAS etc.) say anything about a hierarchy between the two, but rather they ought to be treated as equals.

Me eh no maths man though... I wash out at integrals.

If you wrote this in code such as C++ then answer is 288.

Consumer arithmetic real useful. In fact they could replace a large chunk of Maths with that and finance. Maths real important for the sciences. Countries that produce a lot of scientists have an advantage in Research and Development of new technology and products. Yeah, it important.

But honestly, anybody here ever had cause to use vectors or quadratic equations outside of a classroom ?

Daft Trini · « **Reply #21 on:** April 13, 2011, 04:18:33 PM »

If we have 48/2(9+3), then if we correctly interpret it as

Then we can distribute the 1/2 through the (9+3) term. E.g. 48/2(9+3)=48/2(12)=48*(12/2)=48*6=288

And (12/2) can be written as (9+3)/2, so I see no problem with writing it that way, other than the fact that writing 12 as the sum of three and nine is cumbersome.

Not personally, but I saw it used to identify a man from a helicopter video in the Reginald Denny case after the LA Riots.

24 x 12 = 288

de notation

2(...)

means something a little different from

2 * (...)

there is an implied brackets around the 1st term

so, ‎48÷2(9+3) is really

‎48÷(2(9+3))
