Interesting, does missing the operator between the 2 and (9+3) imply they are the same as being inside brackets?

48/2*(9+3) is definitely 288 , and thats how I read the original question.

Plugging 48/2(9+3) into google = 288.

I only have the scientific calculator in windows

- and thats 288.

BEDMAS isn't really relevant as we are only working with div/multi once the brackets are calculated (BEDMAS = BEMDAS = BEMDSA etc etc)

Quite interesting.

[Edit: Snap!]

I'm with the 288.

But, for me division and multiplication are really the same thing. After all, multiply by 1/2 is the same as divide by 2. (Just like minus 2 is the same as plus negative 2).

So the rule is just, when written like this: left to right.

BO(DM)(AS) = BO(MD)(SA) = ...

48/2(9+3)
= 48/2x12 (brackets first)
= 24x12 (left)
= 288 (right)

Similarly, I'd do 2x6/3 as
= 12/3
= 4 (same answer as 2x2, of course)

Because, seen another way
2x6/3
= (2/1)x(6/3) because 2 = 2/1 (we just don't normally write the .../1)
= (2x6)/(1x3)
= 12/3
= 4

Using casio fx caculator which is programmed for BEDMAS answer is 2
48/2(9+3)
1.Solving inside the brackets first 9+3 = 12 you are now left with 48/2(12)
2. Eliminate the bracket altogether 2 x 12 =24
3. Do final division 48/24 = 2

looks like some calculators are rebelling against google, this cannot end well

That's a description, and your step 2 is weird. What exact keys are you pressing, in the exact order you are pressing them?

NB: Excel also gives the correct answer, 288. (Though the multiplication has to be explicitly written, of course).
In a cell: =48/2*(9+3)

You're a disgrace to the Terminator

**mashman** · 8th April 2011, 20:47

The computer programme says 288.

Tis only 2 if there's brackets around (2(9+3))... bagga

on casio fx-82MS which is a basic scientific
48/2(9+3)=

convert the cartesian form of 3 +j4 into polar form?

ha ha ha = 5 at angle of 53.13 degrees basic farken trig.....

one more vino and i won't be able to do that

You do not eliminate the bracket by multiplying first. BEDMAS only applies as in solve whats INSIDE the bracket first, so once you reach the end of step one then you simply solve left to right.

48/2 = 24
24*12 = 288

You people havent been to school in far too long :P

I happen to have an FX-82MS right here in front of me (Daughters from school).

Typing 48/2x(9+3)= gives 288.

Same on a more advanced FX power graphic calculator I've also got here.

If you are getting 2, you are doing something weird.... missing out the multiplication between the 2 and the brackets.

OK, I admit that's weird (of the calculator). That seems to force it to do things in that order. As though it were 48/(2x(9+3)).

That would freak me out.

**huff3r** · 8th April 2011, 20:51

Also, BEDMAS correctly written should read:

B
E
DM
AS

As division and multiplication have the same importance, as do Addition and Subtraction.

type it in as original 48/2(9+3) do not put 2x as you have done

You are putting the times in the equation. She isnt. That's why they're different.
