Here is the problem as copied and pasted from the title of the thread:

48÷2(9+3) = ?

It is not 48 divided by two times (9+3)

There is a huge difference.

“48÷2(9+3) = ?

It is not 48 divided by two times (9+3)”

The correct order of operations is the same no matter how you pronounce the problem in English.

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

"Here is the problem as copied and pasted from the title of the thread: 48÷2(9+3) = ?

48÷2*(9+3) = 48/2*(a+b)= (48*9)/2+(48*3)/2 = 48*(1/2)*(12) = 12*48*0.5

"It is not 48 divided by two times (9+3)

Yes it is. Otherwise it would be written: 48/(2(9+3)) = 48/(2*12) =48÷(2*12)

"There is a huge difference."

When you insert parenthesis that were never in the original equation; of course there is! You just changed the meaning of the equation by doing so.

Yes it is......order of operations requires that since multiplication and division are equal in terms of solving, you work the problem left to right.

Parenthesis is first (9+3=12)...then, working the problem left to right is 48/2 = 24. THEN 24x12 = 288.

Just change the Obelus (÷)

to a Vinculum (_____)

and the correct answer becomes obvious

        48      
  2(9 + 3)
