288.   going left to right, with order of operations (divide and multiply are interchangable)

its 288. parentheses come first, then you go left to right

so it becomes 48/2(12). then you go left to right so you get 24(12) which equals 288.

done. learn to maths.

well, it depends. technically it is written in an incorrect manner.

although it is pretty clear that you mean the first option, it could be interpreted as

a: 48/(2(9+3)) = 2
b: (48/2)(9+3) = 288

Everyone who said 288 is fucking retarded, yes you do the numbers inside the parenthesis and since the 2 is next to the (12) it is pretty much part of it. So you do 48÷ last, so it ends up being 48÷24=2. NOT FUCKING 288.

72 i think....parenthesis first: 9 + 3=12. Then multiplication: 2 x 12=24. Then addition: 24+48=72

My computer says it's 288 or 2. I get different values based on different languages o.0

I thought 2(12) went first cuz distributive technically comes before division of integers?

P.arenthesis
E.xponents
M.ultiplication
D.ivision
A.ddition
S.ubtraction

Original Problem

48/2(9+3)

Parenthesis

48/2(12) OR 48 / 2 X 12

Exponents (None)

Multiplication/Division (LEFT TO RIGHT)

24 X 12
THEN
288

Unless you take PEMDAS literally (which you should've come to the same conclusion if you did follow it), and disregard distributive properties, yes, it's 288.

For bedmas doesn't it mean brackets first? so you would go 9+3 first not 48 divide 2?

it's for sure 2, just written very poorly.

9+3 is obviously first, so 48÷2(12)

now, sub in x=12

so 48÷2(x)

what would you do in that case?

quite obviously that is equivalent to 48÷2x or 48/2x

now, make it equal to 288 and it's:

48/2x=288
48=288(2x)
sub back in
48=288(24)

obviously wrong.


so, letting it equal 2:

48/2x=2
48=2(2x)
48=4x
sub back in
48=48



therefore it is absolutely 2

brackets = []
braces = {}
parenthesis = ()

You WILL need to learn the difference for programming, higher maths, and theory.

Okay so we all know PEMDAS correct? Well now there is a secondary rule that is a part of this, the Multiplication and Division are on the same level as well as Addition and Subtraction. For example once you break down a problem if you have division and multiplication together you just work from left to right and vice versa, same for addition and subtraction. Therefore 288

Its all how you look at it.

9+3 is obviously first, so 48÷2(12)
sub in x=12
so 48÷2(x)
what would you do in that case?

quite obviously that is equivalent to 48÷2x or 48/2x

now, make it equal to 288 and it's:

48/2(x)=288
24(x)=288
sub back in
288=288

what can "x" be? 12, just as it was subbed for
