================
= (9 - 4)(1 - 2) + 4(-8)÷(-16) Simplificamos -8 en -8 y -16
= (5) (-1) + 4(1)÷(2) Simplificamos 2 en 4 y 2
= -5 + 2
= -3 <-------Respuesta:
Punto b) Solución
================
= (+2)(-8) -(3)(-7) -4(+3)
= -16 + 21 - 12
= 5 - 12
= -7 <--------Respuesta
Punto c) Solución
================
= -10 ÷ ( - 2 - 3) - [4 - (1- 7)]
= -10 ÷ (-5) - [4 - (-6)]
= 2 - [4 + 6]
= 2 - 10
= -8 <--------- Respuesta
