The solution goes like this:
# Answer first the operation in the parentheses.
/9 + ( 4- 3 ) - 17/   then it will become
/ 9 + 1 - 17/       ( nine plus 1 is 10)
/ 10 - 17/           ( seventeen subtract to ten is negative seven)
/ -7 /                  ( when there is absolute value sign, numbers are always positive, so the                        absolute value of  negative seven is seven.)
= 7

/9+(4-3)-17/  and that absolute value ... 
 /9+1-17/
/10-17/
/-7/ 
so it becomes +7
