Step-by-step explanation:
Order of operations Parentheses, exponents, multiplication/division, addition/subtraction (Please, Excuse, My, Dear, Aunt, Sally)
-3 ( - 4 ( 3 - 10 ) - 12 ) - 2 ( - 1 )
Start with your innermost parentheses
subtract 10 from 3 to get -7
-3 ( - 4 ( - 7 ) - 12 ) - 2 ( - 1 )
Multiply -4 and -7 to get 28
- 3 ( 28 - 12 ) - 2 ( - 1 )
Subtract 12 from 28 to get 16
-3 x 16 - 2 ( - 1 )
Multiply -3 and 16 to get -48
Multiply 2 and -1 to get -2
( -48) - (-2)
the opposite of -2 is 2 because the of the double Neg.
( - 48) + 2
add -48 and 2 to get -46
