In the original problem [ 48/2*(9+3) ]

That is not the problem; it is 48/2(9+3).

Showing all the work:

48/(2x9 + 2x3) Distributive property =

48/(18 + 6) Simple multiplication =

48/24 Simple addition

48/24 = 2

Please tell me where this is faulty? Do you even know about the distributive property?

Here is a link that even a third-grader can understand:

The only thing worse than being wrong is to maintain ones ignorance in the face of an undisputable fact.

The correct answer is 2.

“In the original problem [ 48/2*(9+3) ]

It *is* the same problem.

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

I’m starting to understand the distributive argument you and others are presenting better, but I still have a problem not seeing 48/2 as the multiplier outside the parenthesis.

That would make the expression 24(9+3) = 24(12) = 288.

In order to evaluate the 2(9+3) before the 48/2, one would have to ignore the order of operations in the overall equation. I can’t find anything that tells me to ignore the left-to-right precedence outside the parenthesis.

Following your link, when you type the equation in their “Enter Problem” box 48/2(9+3) gave 288, with the solution being 48 over 2 first (24) then multiplied by 9+3 (12). So, it appears my answer of 2 before, is incorrect and should be 288. That’s using your quoted site.
