This ones done to death. Can someone please give us another (more difficult) math question to do/debate when we are soposed to be working. Thanks

There is nothing to discuss, the answer is 41. Simply 'Order of Operations'.
If the equation was 48÷2(9+3) then there is a discussion as technically there are two answers.

Yup. All it highlights is either how retarded some people are or how shite our education is. Or both.

Think of a number between 1 and 100
add 26
subtract 8
add 47
subtract the number you thought off
answer = you are left with 65
maths is fun

I see what your saying with that example BUT, with BODMAS/BIDMAS/PIDMAS where the Division and Multiplication are interchangeable, you work in order from left to right and therefore there is only one answer to the above and it is 288
Edit: But a Casio fx-85MS says its 2 but then a Casio fx-85MS is wrong

In the 'order of operations' multiplication out weighs addition hence the answer 41. If the equation included both division and multiplication then it gets trickier but it then depends on if the the 'Left to Right' rule is applied.
But you're right, you need to add parentheses.
Alternatively, write it out in Reverse Polish (which is what most computer languages use).

You might as well be speaking in reverse polish to me

u should be using Reverse Polish notation 2 clarify the expression
40 40 0 x + 1 +
Or a Prefix ordering in standard Polish notation:
+ + 40 x 40 0 1

I remember having a discussion with a mathematician at uni about the same and he basically said it was all subjective (from what I remember LtoR isn't a hard defining rule, nor is BIDMAS; could be wrong though) in the case of equations like that and any decent mathematician would apply the correct parentheses in the first place.
Edit - Just found this on Youtube, http://www.youtube.com/watch?v=SB3Ekgt1pHw

To refute his claims of no "generally accepted convention" on whether multiplication or division comes first, you may look at division as a form of multiplication.
= 1 / 2
= 1 * (1/2)
= 1 * 0.5
Any division operation can be converted into a multiplication operation, and there is in fact a "generally accepted convention" of performing multiplication (or equal level) operations from left to right.
The answer is 288, and anyone who says otherwise is a testament that our schools are not working.

From here, he just changed a few words around to make it look like he wrote it.

40+40x0+1= stake from Doyle.
(40+40)x0+1= profit for Doyle.
