(−5.2)+(−3.8)–{(−1.2)–[(−0.5)–(−0.7)]}
Just use your BEDMAS rules, but we only have to worry about brackets, which are worked from the most inside to the outer.
(−5.2)+(−3.8)–{(−1.2)–[(−0.5)–(−0.7)]}
= (−5.2)+(−3.8)–{(−1.2)–[−0.5 + 0.7]}
= (−5.2)+(−3.8)–{(−1.2)– 0.2}
= -5.2 - 3.8 - {-1.4}
= -5.2 - 3.8 +1.4
= -7.6
or you can just google it:

(−5.2)+(−3.8)–{(−1.2)–[(−0.5)–(−0.7)]}=?
