Answer 1

1 Simplify {3}^{2}3
​2
​​ to 99
-12+5\times -8-(-16)\div (-1+9)−12+5×−8−(−16)÷(−1+9)

2 Simplify -1+9−1+9 to 88
-12+5\times -8-(-16)\div 8−12+5×−8−(−16)÷8

3 Simplify 5\times -85×−8 to -40−40
-12-40-(-16)\div 8−12−40−(−16)÷8

4 Simplify brackets
-12-40-(-16\div 8)−12−40−(−16÷8)

5 Simplify -16\div 8−16÷8 to -2−2
-12-40-(-2)−12−40−(−2)

6 Simplify brackets
-12-40+2−12−40+2

7 Simplify
-50

RESULTADO FINAL: -50
