: Before I start: you deserve NO HELP for being so damn careless...

: : 2. ([4*8-5=2]^2)-(3-6-(7^2)*9
: : My answer= [1285]
: : Their answer= [397]

: your ([4*8-5=2]^2) is probably (4*8-5+2)^2 : the + and = on same key
: so that's 29^2 = 841

: your (3-6-(7^2)*9 is probably (-3+6+9(-7)^2)
: so that's 3 + 9(49) = 3 + 441 = 444

: 841 - 444 = 397

: Notice that if you add instead, you get your answer: 841 + 444 = 1285

: Has your damn math book been damaged by rain or something?

NO.
You did the same thing they did, forgot the double negative.

You are right, that was supposed to be a +, not an =.
Now, after you simplify, you have:
(841)-(-444)=1285, because 3-6-441=-444, and when you subtract a negative, its like adding a positive. Right?!?!?
