Answer 1

Explicação passo-a-passo:

5° Calcule o valor das expressões numéricas:

a) 8+ (22-12)+45 =

8+(10)+45=

18+45=

63

c) 9 + ( 6+11 ) − ( 10−8+ 2) =

9+(17)-(2+2)=

9+(17)-(4)=

9+13=

22

e) 79- (32 +23) +200 +18=

79-(55)+200+18=

24+200+18=

224+18=

242

g) 32 +23+79 + 18+ 200 =

55+97+200=

152+200=

352

i) (134-34)+(25-13) =

(130)+(12)=

142

b) 16-10+5-1=

6+4=

10

k) 9+(6+11)-(10-8+2)=

9+(17)-(2+2)=

9+(17)-(4)=

9+13=

22

d) 32+200- (23 +79) +18=

32+200-(102)+18=

32+200-120=

32+80=

112

f) 200-(32+23+79 +18) =

200-(55+97)=

200-(152)=

48

h) 17+(15-8) + (4 + 6) =

17+(7)+(10)=

24+10=

34

j) 8+ (20-3)+(30 +24) + (16-13) =

8+(17)+(54)+(3)=

25+57=

82

1) 167-(24-13)+67=

167-(11)+67=

156+67=

223
