48÷2(9+3) = ???

By fernandes_ - 28-07-2015 13:24

This one's got the internet stumped. The main problem here is: when do you stick the value in the brackets into the equation: Before, or after the division is made? The answers either 2 or 288. Both sides have merit. Enjoy your flame wa- i mean debate :P.This one's got the internet stumped.

The correct answer, is that the equation is written with ambiguous notation and that in the form it is currently written as is not valid. It should either be written with the 48 above a line, with 2(9+3) below the line, or written as 48 above the line, 2 below the line, then the (9+3) in a bracket next to it. There is no answer because there is no valid question.The correct answer, is that the equation is written with ambiguous notation and that in the form it is currently written as is not valid.

There is a problem there, I suggest you re-read my post :-p It is written as a pre-schooler would write it, the reason that the divisor sign is not used in algebra is because it allows for ambiguity. It is not possible to write the same equation using the divisor line, which shows you it is not valid.

If you are resorting to a who has the biggest balls already it means you have very little evidence to support your position. The bottom line, is that you could never reverse engineer an equation into this format because you would never be left with the obelus nor an equation without full parenthesis. The equation written in this form is sloppy, the onus is on the writer of the equation to provide clarity that devoids the equation of ambiguity. You don't use the obelus in Algebra because it encourages ambiguity, its as simple as that.

Google's answer, if you actually look at the equation they put into the calculator (above the answer) shows you they they put brackets (parentheses) around "48 / 2" which completely changes the equation. If you put "48÷(2(9+3))" into google then you get 2. And that is the correct answer (and also the correct equation).

We have two possible answers: 288 or 2. If 2 is the correct answer it will be this: 48/2*(9+3) = 2 If we divide both sides for (9+3) we should get the same numbers on both sides, right? So, we get this: (48/2*(9+3))/(9+3) = 2/(9+3) After that, we get: 48/2 = 2/12 24 = 1/6 So, thats wrong. Same stuff for 288: (48/2*(9+3))/(9+3) = 288/(9+3) Getting: 48/2 = 288/12 Then: So, 48/2 = (288/6)/(12/6) And VOILA! 48/2 = 48/2 So, 288 is the right answer.We have two possible answers: 288 or 2.

If 2 is the correct answer it will be this:

So, we get this:
(48/2*(9+3))/(9+3) = 2/(9+3)
After that, we get:
48/2 = 2/12
24 = 1/6
So, thats wrong.

Same stuff for 288:
(48/2*(9+3))/(9+3) = 288/(9+3)
Getting:
48/2 = 288/12

So, 48/2 = (288/6)/(12/6)
And VOILA!

I spoke to a patient of mine at work today who stated what I believe to be true: - both answers are correct a) the answer is 2 is correct because the lack of a multiplication sign is said to imply that the "2(9+3)" should be treated as one unit (instead of the equation saying "2*(9+3)" b) the answer 288 is correct as the lack of additional brackets complicates the issue. I won't comment again, I believe that there is room for both answers to be correct and that the question has been designed specifically to cause arguments. The way maths is taught in Australia, anything added onto brackets, with no sign present in between, should be treated as a whole, aka: ~ Re-draw the equation 48/2(9+3) into algebra: A/B(C+D) = A/(BC+BD) (expanding brackets) Let A = 48, B = 2, C = 9, D = 3 (the equation) = 48/[(2*9)+(2*3)] = 48/[18+6] = 48/24 = 2 As you can see there, if you were to solve this equation algebraically, you cannot get 288.I spoke to a patient of mine at work today who stated what I believe to be true:
