48÷2(9+3) = ?

[wagonrunner]

hmm.

x=2(9+3)
48/x

is that the same as the original equation?

just typed it in my casio with S.V.P.A.m(super visually perfect algebraic methods) got 2, the casio has carried me through a distinction in math, an A in a level math and a maths minor...

Good thing this question didn't come huh?

48/24 = a totally different equation from the original one!

48÷(2(9+3)) = 2

48÷2(9+3) = 48÷2*(9+3) = 288

that there is wrong, because the a number right outside of the bracket, implies that each term inside the brackets be multiplied by it ( it can be before or after the brackets but before is the norm). the bracketed terms associate themselves with the '2' which is the denominator, so the denominator is actually '2(9+3)'
for the denominator to be just '2' alone, the terms 48/2 would need to be in brackets i.e. (48/2)...
... that is the purpose of the brackets, to separate them from being done left to right, and to be worked out before and the result being used after.

think about it like this,,, if u work out the brackets first, u would have
48/2(12)=

now if this was the sum, then what would u work it out to be?

48/2 cannot be worked out the same stage as 9+3 because the 9+3 is bracketed and the 48/2 is not.

the steps have to be:
48/2(9+3)=
48/2(12)=
48/24=2

if u could work out the 48/2 at the same stage as 9+3, then there is no reason for putting the 9+3 in brackets... just leave it out.

I stand corrected but...* the brackets first, what # you get then * by the # in front of bracket ...then divide by first #.

QED.....for those who know !!!

[Rutless Tiida]

Interesting I put
48/2(9+3) in my sharp I get 2
I then put
48/2*(9+3) and get 288

but I would have to say that because the sum was not written as (48/2)(9+3) that it would have to be 48/24 = 2

Wouldn't have mattered, would still have gotten the correct answer

[Gladiator]

I always knew it as brackets and everything associated with brackets first...2(9+3)

Then continue with the rest which will give the answer as 2.

For the other questions.

[~Vēġó~]

the answer IS 2....

[Chemical]

sound like a guy did Chemistry wrt applied maths?

^^Correct !

[Stephon.]

the answer IS 2....

Step 1: 48÷2(9+3) = 48÷2(12)
Step 2: 48÷2x12
Rule: BODMAS
Step 3: Division first
48÷2x12 = 24x12
Step 4: 24x12 = 288

why every time i see your name i need to shout it?

When did the brackets suddenly disappear from 2(12) to 2x12 ?

(12) still needs to be solved. You cannot even work the problem without getting rid of those brackets!

ok.. i didnt read the whole thread.. but what the hay are u talking about? 12 needs to be solved?

a(b) = a.b = a*b

ent ???

[TK!]

ppl.. pls avoid adding brackets where you *think* they belong. you can remove brackets, once u follow the rules.

[FullStop]

a(b) = a.b = a*b

does that mean 2(3)---which is clearly =2.3=2*3?
cus if ur saying that then u cant say 8÷2(3)=12, cus is clearly 8÷6.

48÷2(9+3) =

48÷(18+6) =
48÷24 =
2

[phreakazoid]

If 48÷2(9+3) = 48÷(2x9+2x3) , Why wasn't it stated like that in the first place?

[sharkman121]

dis ched still goin on..??

the answer will still always be 2

[Bizzare]

You're not serious about that question right?
