Answer:
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
