But in this particular problem, where order of operations are in play, you can't just add, until AFTER you divide.

You can add 9+3 first because its in the PARENTHESIS where the P in PEMDAS comes from. You solve/simplify whats IN the parenthesis.

as shown here:
http://www.mathgoodies.co...l7/order_operations.html

where ALL examples simplify whats in the parenthesis FIRST.

Yea but this special distributive property rule isn't in play in any of those problems. It is here.

Show an example of your distributive property from a source.

Look at the example shown at the 2 minute mark. THE FINAL ANSWER is 266 in that problem which is what is left.

exactly! there is an implied set of parenthesis around that. if they are like terms you combine and drop the parenthesis. if they are not like terms, you can just drop the parenthesis outright

[ncmalko1]

Step one is to do the parenthesis completely which is 24
Step two is to divide 48 by 24

THE ANSWER IS 2

48/2(9+3)

Using Quotient rule and Distribution rule the problem can be re-written as

48*.5(9+3)

Which still gives you 288.

thank you.

for the parethenses purists...the 48/2 should be multiplied by the value in the parenthesis, not just the 2.

which gives you the correct answer, 288.

Only true if 48 / 2 were (48 / 2).
Sorry bro.

Y'all fail to realize that problem doesn't involve Order of Operations.

That's the key.

What I find most amazing is that people still don't know how to use PEMDAS. Arguing that you HAVE to multiple then divide. That argument is already proven irrelevant and put down MULTIPLE times. But hey look at the bright side you learned basic math in Niketalk.


The real argument here is what to do with 48/2(12)

Are people saying you multiple the 48 because the 9 plus 3 are in ( ). That is wrong. You don't multiply is by 2 and then keep the brackets up and multiply by 48 also. Brackets don't mean you continually multiply it.

Sorry bro.

doesn't 48÷2 = 48
                           ------ ?
                               2

if so, i don't see your argument.

your answer is only true if 2(9+3) were (2(9+3), which it IS NOT in the original equation.

[stay lurkin]

BUT, 288 doesn't even check, tho, so how could it possibly be the right answer?

What is this I don't even

2(9 + 3) is equivalent to (2 * 1(9 + 3)) which is the extended version. 2(9 + 3) is simplified. It's implied.

Divide it first. Then multiple. I learned that if the equation is this short and only 2 basic operations are left in the problem ( Multiplication and Division) ( Addition or subtraction) at this point one just does basic math and PEMDAS becomes void. So in this case divide 48 by 2 and then multiply by 12. This only is used though if the problem has only addition and subtraction remaining or if the problem has multiplication and division remaining. Even though there is a parenthesis here it serves the same purpose as a multiplication sign. I've literally only seen this example in my lifetime of doing math once.
