I learnt Math by force. Not until later when I presented my dad with a calculus problem. Hihihi.
(21+15+5)!!! thithihihihihihi. My dad would pinch me so hard if he saw me do that!!

@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.

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

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)
