Resposta:
Explicação passo-a-passo:
A)
(20-3)+(7+5)=
= 17+12
= 29
B)
50+{[15+(3-9)+1]}=
= 50+{[15+(-6)+1]}
= 50+{[15-6+1]}
= 50+{[9+1]}
= 50+{10}
= 60
C)
15-(7+2)-8=
= 15-(9)-8
= 15-9-8
= 6-8
= -2
D)
18+(9-15)-8=
= 18+(-6)-8
= 18-6-8
= 18-14
= 4
E)
7-[4+(3-5)]=
=7-[4+(-2)]
=7-[4-2]
= 7 - [2]
= 7 - 2
= 5
F)
{5 - 532-(50-20]}=
={- 527-(30)}
= - 527-30
= - 557
G)
{16-[12+(20-25)]}=
= {16-[12+(-5)]}
= {16-[12-5}
= {16-[7]}
= 16-7
= 9
H)
10-{30+[4-(5+2)]}=
= 10- {30+[4 - (7)]}
= 10 - {30+[4-7]}
= 10 - {30+[-3]}
= 10 - {30-3}
= 10 - {27}
= 10-27
= - 17
I)
= {-2+[3-0-(8+1)]-10}
= {-2+[3-(9)]-10}
= {-2+[3-9] - 10}
= {-2+[-6]-10]
= {-2-6-10}
= {-8-10}
= - 18
