48÷2(9+3) = ?

288

48/2=24

9+3=12

24*12=288

You do the division first, and the parenthesis separately, then multiply the results.

The answer is 2

Please
Excuse

Dear

Sally

Parenthesis -> Exponents -> Multiplication -> Division -> Addition -> Subtraction

48/2*(9+3) = 48/2(12) = 48/24 = 2


It's actually:

Parenthesis -> Exponents -> Multiplication/Division -> Addition/Subtraction with precidence for items on the same tier = left to right rule.

48/2(9+3)=x
48/2(12)=x
24(12)=x
288=x

48÷2(12) = ?

48÷24 = ?

48÷24 = 2

48 = 2x24

48 = 48

is it

48/ (2*(9+3))

or

(48/2)*(9+3)

?


it's exactly what it says, 48/2(9+3) which is the same when written as (48/2)*(9+3). if it was 48/(2(9+3)) then it would be written that way instead. there is no ambiguity, the expression is completely valid and always equals 288. math is not subjective.

288

48/2=24

9+3=12

24*12=288

your order of operations is incorrect


yes he did make the mistake of not doing parenthesis first but he got the right answer.

There's no other answer than 288. Simple order of operations. There are some exceptions as to how multiplications can be interpreted, but in this case, it's unambiguous.

Next.


It's very ambiguous. This is a troll post due to the nature of the division symbol, which leaves the process open to interpretation. You can either do (48/2)*(9+3), or 48/(2(9+3)).

It's a troll post.

Actually the correct answer is that the question is rigged in the way it's presented. There is a reason math classes stop using the division symbol usually after elementary school, it's ambiguous and confusing. There is no right answer, because the question is flawed.

BEDMAS! If you didn't get 2 you're doing it wrong, take some actual math classes.

Screw aunt sally.


HEY!! Aunt Sally will kick your new maths butt!! Watch it!

By order of operations, it is (48 / 2) × (9 + 3) = 24 × 12 = 288.

In the case of ambiguities, you go left to right. If you suggest otherwise then you are changing the question.

48/2*(9+3) = 48/2(12) = 48/24 = 2


or you could use a calculator/wolfram alpha and get 288.

multiplication and division have equal priority, in case of a tie you go sequentially from left to right, so you divide 48 by 2 before multiplying by 12.

The troll is around how many people can't do basic math, run to the calculator, and depending on if your calculator is a piece of !@#$ 4-function or something that you can put () into you're going to get different answers.

For those of us who can actually, you know, do math there is one answer. It's 288.
