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 - 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.

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.

Should be 13.Erick your calculator appears to be doing Linear processing insread of following BODMAS
