Answer 1

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
