Answer:

Step-by-step explanation:

Order of operations:

a)parenthesis

 b) exponents

 c) multiplication or/and division from left to right

 d) addition and/ or subtraction from left to right

The most inside parenthesis  are (-4) , (-10), (-5) and those are just negative numbers that we need to combine with others:

4x negative 4 = -16;  2 - negative 10 = 2+10 = 12; and 9 +negative 5 = 9-5 = 4

( 4 x (- 4 )) / ( 2- (-10) +9 +(-5)) =

( 4 x -4 ) / ( 2+10 +9 -5) =

-16 / (12+4) =

-16 / 16 =

-1
