Calcule o valor das seguintes expressões:

a) -10 -(-7+ 4 -6)
b)-14 -(7 -6) + (8- 5)
c) 10 - {-2 +[1 +(+4) -8]}
d)25 + [-4 +1 -(-3 +7)]
e)21 - [-17 +(19 -4) +12]
f) 39 + [-10 -(+32 -10 -8) +9]
g)6 -{-9 + [-1 +14 - (8 +17 -12)]}​

Answer 1

a) -10 -(-7+ 4 -6)= -1

b)-14 -(7 -6) + (8- 5)= -12

c) 10 - {-2 +[1 +(+4) -8]}= +9

d)25 + [-4 +1 -(-3 +7)]= +18

e)21 - [-17 +(19 -4) +12]= +11

f) 39 + [-10 -(+32 -10 -8) +9]= +24

g)6 -{-9 + [-1 +14 - (8 +17 -12)]}​= +15
