Answer 1

Respuesta:

C. - 31

D. 9

E. - 3

F. 37

G. 30

H. 4

I. - 15

Explicación paso a paso:

C. (-20)+{(-15)-11+7+8}

= (-20)+{(-15)-4+8}

= (-20)+{(-15)+4}

= (-20)+{-15+4}

= (-20)+{-11}

= -20-11

= -31

D. (-4) + 6 - { 7 - [9 - 5] + 3 + (-13)}

= (-4)+6-{7-[4]+3+(-13)}

= (-4)+6-{7-4+3-13}

= (-4)+6-{3+3-13}

= (-4)+6-{6-13}

= (-4)+6-{-7}

= -4+6+7

= 2+7

= 9

E.{4 - 5 - [10 + 3] + [3 + 8]}

= {4-5-[13]+[11]}

= {4-5-13+11}

= -1-13+11

= -14+11

= -3

F. 17 - {5 +[(-6) - 3 + (2 - 3)] - 15}

= 17-{5+[(-6)-3+(-1)]-15}

= 17-{5+[-6-3-1]-15}

= 17-{5+[-9-1]-15}

= 17-{5+[-10]-15}

= 17-{5-10-15}

= 17-{-5-15}

= 17-{-20}

= 17+20

= 37

G. 9 - {3 - [(10 +5) - (8 - 17)]}

= 9-{3-[(15)-(-9)]}

= 9-{3-[15+9]}

= 9-{3-[24]}

= 9-{3-24}

= 9-{-21}

= 9+21

= 30

H. 26 - {18 - (-3) + (-10) + [32 - 17 + (-12) + 8)]}

= 26-{18-(-3)+(-10)+[32-17-12+8]}

= 26-{18-(-3)+(-10)+[11]}

= 26-{18+3-10+11}

= 26-{21-10+11}

= 26-{11+11}

= 26-{22}

= 26-22

= 4

I. 13 - 12 + 5 + {(-4) - [5 + 6 + (7 + (-8) + 1)] - 6}

= 13-12+5+{(-4)-[5+6+(7-8+1)]-6}

= 13-12+5+{(-4)-[5+6+(0)]-6}

= 13-12+5+{(-4)-[11]-6}

= 13-12+5+{-4-11-6}

= 13-12+5+{-15-6}

= 13-12+5+{-21}

= 13-12+5-21

= 1+5-21

= 6-21

= -15
