Answer 1

Resolva as expressões numéricas

a) 30-(6-1)= 30 - 5 ==> 25

b)15+(-3+2)= 15 - 1 ==> 14

c)-6-(-3+2)=  - 6 + 1 ==> - 5

d)18-(-5-2-3)= 18 + 10 ==> 28

e)4+(3-50+(-2-6)= 4+(-47-8)= 4 - 55 ==> - 55

Answer 2

a) 30-(6-1)=
     30-6+1
       25

b) 15+(-3+2)=
     15-3+2
        14

c)-6-(-3+2)=
    -6+3-2
      -5

d) 18-(-5-2-3)=
     18+5+2+3
        28

e) 4+(3-50+(-2-6)=
     4+(-47-8)
      4-55
       -51
