When you have THE SAME SIGN, the result is always +
+ with + = +
- with - = +

WHEN YOU HAVE DIFFERENT SIGNES, the result is -
+ with - = -
- with + = -

so
-(-A-B+2C)=
A+B-2C

distributive property
a(b+c)=ab+ac
remember that there is an invisible 1 infront so
the equation is really
-1(-A-B+2C)
negative times negative=positive
negative times positive=negative
-1(-A-B+2C)=+1A+1B-2C=A+B-2C
the answer is A+B-2C
