Simplify the following by removing the grouping symbols:
a. -[4-(-5)]-16
b. -18-[-4-(-8)]
c. -{4x-(3y-16x)}
d. -{16x-(12-3x)}
e. -{-4-[10-(-6)]}-[8-(-18)]
f. -{-9-[-12-(-7)]}-[-15-(-2)]
------------
f. -{-9-[-12-(-7)]}-[-15-(-2)]
= -{-9-[-12+7]}-[-15+2]
= -{-9-[-5]}-[-13]
= -{-9-[-5]} + 13
= -{-9+5]} + 13
= -{-4} + 13
= 4 + 13
= 17
