Good answer.
And leave it to people on a political site to manage to ignite a debate over an equation!!!!!

Hittin’ Jenny?
Be aware that multiplication and division are actually at the same precedent, as are addition and subtraction. The mnemonic order omits this grouping. Do a search on “order of operations” or “mathematical precedence” and check it, if you like.
I know (at least I think I know).
But I didn’t put the parentheses around the 48/2. Google did.
Why is that? Try it yourself. Click the link in post 6.
When I did it in my head, the answer I got was 288.
When I used a computer, the answer I got was “a jar of almonds”.
I found it, I found her number on the wall..... for a good time, call!
Easy: 48/2(9+3)=ATT :)
**the lack of a stated arithmetic operator between the 2 and the (9+3) associates them. That is the way you can build in an implied * to the equation
answer is 2**
That was the way I was taught. In ENGLISH
fortyeight divided by the answer from 2 times the answer from 9 plus 3 equals what.
288
Post 35 explains it more succinctly than I could .. but that’s how I learned it.
Thank you for the translation. You said it much better than I.
you are absolutely correct
Please check your answer using more than the mnemonic. Search for “order of operations” to get the whole story.
Left-to-right, the answer is 288. ;-P
The correct answer, with standard mathematical notation, is 2. The other answer occurs by dividing 48 by 2, yielding 24, and then multiplying THAT by 12. Bad notation!
I think the answer is 2. The 2(9+3) is, I believe, a notation that the 2 was factored out the 9+3. So, I think we’d factor the 2 back in before doing the division. 2(9+3) is the same as (18+6).

Excel says 288.
Both are correct, but the question is asked differently on each. One calculator is doing RPN (Reverse Polish Notation).
