Hallar las cifras que debemos escribir en lo​

Answer 1

Respuesta:

a)-5-[-17+ (15 -6)]+ (-15-8)-{-1+ (8- + (7-10)]

-5-[-17+ (9)]+ (-23)-{-1+ (8- + (3]

-5-(-17+ 9) -23-[-1+ (8+3)]

-5-(-17+ 9) -23-(-1+11)

-5-8 -23+10

26

b)-13-4+ [9+(-5-6+12) + (-2)] - 5)

-13-4+ [9+1 + (-2)] - (5)

-13-4+ (9+1-2) - 5

-13-4+ (8) - 5

-13-4+ 8 - 5

-14

c)-15+[(-3-18-4+(6-1)] + 12-[6-(5-11)]

-15+[-3-18-4+(5)] + 12-[6-(-6]

-15+(-3-18-4+5) + 12-(6-6)

-15+(-20) + 12-0

-15+20 + 12

17

D)-14-{-9-[15-(16+31)]-[-12 + (-8-7)

-14-{-9-[15-(47)]-[-12 + (15)]

-14-[-9-(15+47)-(-12 +15)]

-14-[-9-(62)-(3)]

-14-(-9-62-3)

-14-74

-88

e) 4-15- [7- (3-2-6) -8]-(-3-(7-5)

4-15- [7- (-7) -8]-[-3-(2)]

4-15-(7- 7 -8)-(-3+2)

4-15-(-8)-(-1)

4-15-8-1

-20
