Answer 2

Hi friend!

Its me Sheena here...

-17+[2-{(-8)+3-(9*6+1-13*3)]

= -17+[2-{(-8)+3-(54+1-39)
= -17 +[2+8+3-54+1-39]
= -17 + [13-54+1-39]
= -17 + [-3]
= -17 -3
= -20

This is the solution of the problem : )

To know how the signs change follow the below points >>>

 + + (when two positive signs nearby) 

 =>     + (add them)

          + (The answer will 
  =>         be positive sign)
______________________________

 - - (When two negative signs nearby) 

   =>               + (add  them)

    =>    + ( The answer will be 
                      in  positive sign)

__________________________________

+ - ( when a negative sign and a positive sign nearby)
 
  =>   - (Subtract both of them)
                                                                
  =>  The answer will be the sign of
                     Greater number
