    It's a badly written problem precisely BECAUSE it is vague.

    If a problem can't be conclusively solved as written then it is a crap equation.

    When first looking at it, and going by how I learned and was taught math for the last 40 years, the answer would be 2.

    Again, Math is stupid. But, despite that, I was always taught that the number on the outside of the parenthesis had more pull to the parenthesis. 2(x + y), in the answer 288, they want to take 2 away from the parenthesis, which I thought was against the rules. 48/2 (12) attempts to do just that.

    I was taught once it's only multiplication/division or add/sub you just got left to right....so 288.

    It is 288. I don't see it as poorly written.

    I am left wondering if people are just joking, or if people really can't read a simple operation?

    IIRC the rules are:

    1. Inside parenthesis first
    2. Attached to parenthesis 2nd
    3. Loose bits 3rd.

    So:

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

    I get 2 as the answer.

    How did you come up with 288? Any why did you divide before you multiplied. Maybe now you'll see why.

    I can't tell if people are trolling anymore. It's probably been awhile since you've taken a math class, just admit you are wrong so we can end this.

    Tutorial


    This tutorial is designed to help you solve problems correctly by using the 'Order of Operations'. When there is more than one operation involved in a mathematical problem, it must be solved by using the correct order of operations. A number of teachers use acronyms with their students to help them to retain the order. Remember, calculators will perform operations in the order which you enter them, therefore, you will need to enter the operations in the correct order for the calculator to give you the right answer.

    * In Mathematics, the order in which mathematical problems are solved is extremely important.

    Rules

    1. Calculations must be done from left to right.

    2. Calculations in brackets (parenthesis) are done first. When you have more than one set of brackets, do the inner brackets first.

    3. Exponents (or radicals) must be done next.

    4. Multiply and divide in the order the operations occur.

    5. Add and subtract in the order the operations occur.



    AND ANOTHER ONE

    http://www.mathgoodies.com/lessons/vol7/operations_exponents.html

    Rule 1: Simplify all operations inside parentheses.
    Rule 2: Perform all multiplications and divisions, working from left to right.
    Rule 3: Perform all additions and subtractions, working from left to right.

    However, the problem above includes an exponent, so we cannot solve it without revising our rules.

    Rule 1: Simplify all operations inside parentheses.
    Rule 2: Simplify all exponents, working from left to right.
    Rule 3: Perform all multiplications and divisions, working from left to right.
    Rule 4: Perform all additions and subtractions, working from left to right.

    We can solve the problem above using our revised order of operations.





    Come on guys. 288. Always has been. Always will be.

    Are people who didn't answer 288 trolling? I can't tell.

    People who answered 2 are idiots, trolling or not. They never learned math correctly. The answer is 288.

    48÷2(9+3) = 48÷2x12

    now do the math.

    Left to right:
    48/2=24
    24*12=288
