Respuestas a la pregunta
Respuesta:
A. 172
B. -104
C. 1900
D. -1212
Explicación paso a paso:
A. 200+ [(-32/2) - (-15/5) + (-15)]
200+ [(-16)- (-15/5) + (-15)]
200 + [(-16) - (-3) + (-15)]
200 + [(-16) - (-3) -15]
200 + [-16 - (-3) - 15]
200 + [-16 + 3 - 15]
200 + [-31+3]
200 + [-28]
200 - 28 = 172
B. -80+ [(-2) + (40/5)+ (360/ -12)]
-80 + [-2 + (40/5)+ (360/ -12)]
-80 + [-2 + (8) + (360/ -12)]
-80 + [-2 + (8) + (-30)]
-80 + [-2 + 8 + (-30)]
-80 + [-2 + 8 - 30]
-80 + [-32 + 8]
-80 + [-24]
-80 - 24= -104
C. 20 x [(-2 x 20)+(480/4)-(-15)]
20 x [(-40)+(480/4)-(-15)]
20 x [(-40)+(120)-(-15)]
20 x [-40+(120)-(-15)]
20 x [-40+120-(-15)]
20 x [-40+120+15]
20 x [-40+135]
20 x 95= 1900
D. [(0/1000 ) + (-12 / 1) -(120 x 10)]
[0+ (-12 / 1) -(120 x 10)]
[0+ (-12) -(120 x 10)]
[0+ (-12) - (1200)]
[0 - 12 - (1200)]
[0 - 12 - 1200]
[-1212]= -1212
