Don't use Nivea for Men as your lubricant. It leaves you dry longer.

for it to be 288 it would have to be written as (48/2)(9+3), as it is not written like this it must be 2.

ditto the only way to get 288 is if it was produced as 48/2x(9+3) or as above.

written as the way the op did it equals 2. the way the op wrote the equation places it as 42 over 2(9+3)

I think you're all just taking the piss.

It's not even a real question.

It's 288 if you have your restricted and have just passed a practical exam for your full license. Now shut up and go to bed. Don't make me come in there!

What you've written (I've bolded) is actually exactly the same as the original question. 2( is actually 2x(

Therefore, the brackets are resolved, (12) and then it goes from left to right, as multiplication and division have the same priority. It's 48 / 2 x 12 = 288.

For it to be as you say in the second, the equation would need to be on two lines. Brackets would be implied on both lines, to resolve each line, then the division.

yes correct but the whether the multiplication symbol is there or not changes the status of the 2. when its just 2(9+3) then it is part of the brackets piece of bedmas and gets done before the division.
If the multiplication symbol is in place then multiplying what's in the brackets happens after the division of 48/2
all depends how its wtitten too, but as written in the op answer=2
see like this ----

two !

Right I've had my weetbix and the alcohol is mostly out of my system and I still cannot see how you get 288.

I interpret equation written as thus:
48
-----------
2(9+3)
Following the rules of BEDMAS
1. Solve inside the brackets 9+3 =12 which makes equation 48/2(12)
2. Expand the brackets 2x12=24 which now makes 48/24
3. Solved = 2

Cross mutipication of fractions still comes up as 2 when solving inside brackets first:
48 12
___ x ___ = 2
2 1

It is my thought that if it is done as so that 24 x 12= 288 the brackets are now being expanded last?

my head hurts!... is this how they work out the regos?

**marie_speeds** · 9th April 2011, 06:52

Can't get my fractions sorted sorry should show 48 over 2 multiplied by 12 over 1

This is correct.
The multiplication step is implied as Gremlin says.
