Explanation:
remember the priorities of operations :
1. brackets
2. exponents
3. multiplications and divisions
4. additions and subtractions
so,
(4 - (-2 - (1 + 3)))×-6 - 13 - 32 - 48 - 60 =
= (4 - (-2 - 4))×-6 - 13 - 32 - 48 - 60 =
= (4 - -6)×-6 - 13 - 32 - 48 - 60 =
= (4 + 6)×-6 - 13 - 32 - 48 - 60 =
= 10×-6 - 13 - 32 - 48 - 60 =
= -60 - 13 - 32 - 48 - 60 = -213
