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
