288.

48/2(9=3)

=48/2(12)

This where people going wrong...

=24(12)

=288.

In BEDMAS Multipulcation and Division are equal. Divide and Multiply in the order they occur.

I hope I didn't mess up anywhere.

48/2 x (9+3)

48/2 x 12

24 x 12

288

dunno where people are getting 2 from

They are doing,

48/(2(9+3))=2

which isn't incorrect.

For me it's: 48/2*(12)

48/2

24*(12)= 288

Lol guy under me ya jelly.

the way you have it written it's going to be 288. If there had been a second set of parenthesis on the bottom it would be 2.

Edit: satsot said what i was going to while i was typing, faggot

You're probably doing (48/2)(9+3)

^ You guys that are getting 288 are assuming that the 48/2 is in a bracket of its own, when it isn't. The problem is 48 / 2(9+3), which implies that the 48 is divided by the whole of 2(9+3). You're thinking it's (48/2) x (9+3)

It's 2

Brackets Indices Division Multiplication Addition Subtraction - BIDMAS

You do the bracket first: (9+3) which is 12, then multiply that by the 2, so 24 as the denominator, then you divide 48 by the 24, giving 2

I'm doing Maths at Uni next year, don't you dare tell me i'm wrong

Order of operations = PEMDAS

[P]arenthesis

[E]xponents

[M]ultiplication

[D]ivision

[A]ddition

[s)ubtraction

48 / 2(9+3)

first thing you would do is solve inside the parenthesis (9+3) = 11

48 / 2 * 12

now, multiply, 2 * 12 = 24

48 / 24

now, solve. 48 / 24 = 2

2.

And, BTW, I just checked my TI-84 Plus for shits and gigs, and oh yeah...

The right answer is 288.

There is only one parentheses, you do that first.

      48/2(9+3)

>>  48/2(12)

>>  48/2*12

PEMDAS = (STEP 1)Parentheses, (STEP 2)Exponents, (STEP 3) Multiplication, (STEP 3) Division, (STEP 4) Addition, (STEP 4) Subtraction

Though Multiplication and Division have separate letters in the acronym, you actually do multiplication and division in the same step from left to right.

In short, as the 48/2 comes before the 2*12, that function must be done first.

>>  48/2*12

>>  24*12

>>  288

On bodybuilding forums, there was an easy mathematical question that sooo many idiots got wrong.

48 / 2(9+3)

What's your answer? I have mine and I know it's correct.

288

simple order of operations

edit: how can so many of you get 2? thats not right at all lol

Apparently we were all taught differently. Everyone on the BB forums was blaming Canada for the 288 answer. We learned

BEDMAS

Brackers

Exponents

Division

Multiplication

Addition

Subtraction

From what I get from it, the whole world (possibly less the U.S) was taught a different way.

48 / 2(9+3)

48/2(12)

48/24

2

If you don't get this, you need to go back to grade 6. Always solve to get rid of the brackets first.

It is 288.

48 / 2(9+3)    Original problem

48 / 2(12)      Add what's in parenthesis

24(12)           The 48 / 2 is assumed in parenthesis, just like how in 2(2) you assume the first 2 to be in parenthesis. It is just not obligatory to write it there because it is ambiguous.

288                Boom

You're dumb.

PEMDAS, then left to right.

The answer is 288.

Left to right has nothing to do with this.
