start simplifying inside the highest imbedded paranthesis

-(-7) -(-(-7)) -(-(-(-7))) = -(-7) -(-(-7)) -(-(+7))
= -(-7) -(+7) -(-7) = +7 -7 +7 = 7

Follow me step by step:

-(-7) -(-(-7)) -(-(-(-7)))
= 7 -(-(-7)) -(-(-(-7)))
= 7 -(7) -(-(-(-7)))
= 7 -7 -(-(-(-7)))
= -(-(-(-7)))
= -(-(7))
= -(-7)
= 7

do the inside of the brackets first

-(-7) -(-(-7)) -(-(-(-7)))
-(-7) -(-(-7)) -(-(7)))
-(-7) -(-(-7)) -(-7)
-(-7) -(-(-7)) +7
-(-7) -(7) +7
7 -7 +7
7
