Answer 1

first solve the bar,then remaining part
$5) \: 11 - (( - 8) - (10 - (9 - bar7 - 4))) \\ = 11 - (( - 8) - (10 - (9 - 3)) \\ = 11 - (( - 8) - (10 - (6)) \\ = 11 - (( - 8) - (10 - 6)) \\ = 11 - (( - 8) - 4) \\ = 11 - ( - 8 - 4) \\ = 11 - ( - 12) \\ = 11 + 12 \\ = 23$
$( - 9) - (( - 5) - (11 - (8 - bar(5 - 2))) \\ = ( - 9) - (( - 5) - (11 - (8 - 3)) \\ = ( - 9) - (( - 5) - (11 - 5)) \\ = ( - 9) - (( - 5) - (6) \\ = ( - 9) - ( - 5 - 6) \\ = ( - 9) - ( - 11) \\ = - 9 + 11 \\ = 2$
$7) \: 10 - (8 - (11 + 30 \div (4 - bar(5 - 7))) \\ = 10 - (8 - (11 + 30 \div (4 - ( - 2))) \\ = 10 - (8 - (11 + 30 \div 6) \\ = 10 - (8 - (11 + 5) \\ = 10 - (8 - 15) \\ = 10 - ( - 7) \\ = 10 + 7 \\ = 17$
