ok, I might be wrong in my explanations by the very meaning of my words, but for sure it applies logically....at the point where you only have + and - signs The placing of brackets at this point (22+32) - (21+15+5) is where they went wrong.....and its actually confusing if care is not taken [and here is the point where the-not-soooo-maths-savy skunks start thinking in a complex way and do magic!!] At this point, (22+32) - (21+15+5) they should actually have done this, if they really have to follow BODMAS rules and placing of braces... (22)+(32)+(-21)+(15)(+5) In fact, me thots.... their complexing thinking made them assume - sign in 22+32 - 21+15+5 was to separate the equation into 2 parts, so they got (22+32) - (21+15+5)!!! thithihihihihihi.

@Gregory,
I disagree. BODMAS is used on all operators and not "when u have multiplication and division signs (in a complex equation)" as you put it.
BODMAS is just a system that helps us remember the order in which to deal with the operators.
But I agree with you on the answer.
operators between, u just apply simple arithmetic and logic. U just add subtract add blah blah, whenever u see the appropriate sign!!!!!!
Mul and division signs r binary operators, + and - are unary operators....if u don't hv the capacity to sink this in grey matter, don't bother trying any harder, coz that the way maths is!!! duhhhhhh!!!!!!! Where r the mathematicians?!!!
53 is the answer!! CASE CLOSED! Even a standard 8 pupil would do this in seconds, whatever happened to our maths.........!!!!!!!

@Collins was wrong at this point
=>(22+32) - (21+15+5)
Without the brackets as it was before it would be
22 + 32 - 21 + 15 + 5
Then Addition:
22 + 32 + 15 + 5 = 74
Then Subtraction:
74 - 21 = 53
. . . Ans = 53

BODMAS : 11 x 2 + 32 - 21 + 5 x 3 + 5 x 1
since we have no brackets, or division, we go to multiplication: hence
(11X2) +32-21+(5X3)+(5X1)
=> 22 + 32 - 21 + 15 + 5 Then Addition
(22+32) - (21+15+5) => 54 - 41
=> 13.
My 2 Cnts.

Such a mathematical calculation does not require BODMAS, I was taught that in school, since there is not bracket. If done as it is, the answer should be 53. Therefore the 'winner' of that 160K, is just 'one of the few picked up' guys and declared them winners.

IMO, The link provided by @Erick is right... the answer should be 53; and @Brian the calculator did use BODMAS.

For all I know, BODMAS comes in when u have multiplication and division signs (in a complex equation), and its here that u r required to put brackets, for simplicity sake. When u reach the point where u have + and
