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. 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.
