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 + 15 + 5 = 74
22 + 32 - 21 + 15 + 5
Then Addition:
Then Subtraction:
74 - 21 = 53
.
. . Ans = 53
