b) 25 - ( 15 + 6 : 3) = (R: 8)
c) 25 +[7 + ( 8 - 4 :2)] = (R: 38)
d) 60 - [8 + ( 10 - 2 ) : 2] = (R: 46)
e) 80 - [ 22 + ( 5 . 2 - 1 ) + 6] = (R: 43)
f) 14 : 2 + [ 13 - ( 4 . 2 + 1 ) ] = (R: 11)
g) [ 30 + 2 x ( 5 – 3 ) ] x 2 – 10
h) 20 : 10 + 10
i) 10 + [ 4 + ( 7 x 3 + 1 ) ] – 3
11) Resolva as expressões numéricas:
a) 8 – ( 1 + 3)
b) 7x 3 – 2 x 5
c) ( 13 – 7 ) + 8 – 1
d)4 x 3 + 10 : 2
e) 15 – ( 3 + 2 ) – 6
f) 40 – 2 x 4 + 5
g) ( 10 – 4 ) – ( 9 – 8 ) + 3
h) 50 – 16 : 8 + 7
i) 50 – [37 – ( 15 – 8 ) ]
j) 32 : 4 : 2 : 2
l) 28 + [ 50 – ( 24 – 2 ) – 10 ]
m) ( 13 + 2) x 3 + 5
n) 20 + [ 13 + ( 10 – 6 ) + 4 ]
o) ( 7 + 2 ) x ( 3 – 1 )
p) 52 – { 12 + [ 15 – ( 8 – 4 )]}
q) ( 4 + 2 x 5 ) – 3
r) 7 + 15 : 3
s) 20 – ( 15 + 6 : 3)
t) 4 x 5 + 1
u) 15 + [ 6 + ( 8 – 4 : 2 )]
v) 10 : 2 + 8
x) 40 – [ 3 – (10 – 2 ) : 2 ]
z) 32 + 12 : 2
Faça com capricho e dedicação!!!!
Boa sorte!!!!
