Explicação passo-a-passo:

a) (47 - 2 + 5) + (16 ÷ 8) =

50 + 2

52

b) [49- (6 x 6 - 15) + 7]=

[49 - 21 + 7 ]

56 - 21

35

C) 54 + {16 - (4 x 4 - 10) 3]) =

54 + [16 - 6 . 3 ]

54 + -2

-56

d) 15 + [6 + (3x 8-21) + 2]) =

15 + [6 + 3 + 2 ]

15 + 11

26

e) (12+ [8 x (19-5) - 10]) =

(12 + [8× 14 - 10])

( 12+ 102)

114

f) 6 x [3 + (9 x 3 - 22)+2] =

6 × [3 + 5 +2]

6 × 10

60

g) 76+ (15 ÷ (6 ÷ 2 + 2) + 1) =

76 + (15÷ 5 +1)

76 + 4

80

h) 4 x (19 + [5 + (32 ÷ 4 - 6) - 10]=

4 × (19 + [5+ 2 -10])

4 × (19 + -3)

4 × -22

-88

i) 60 - 48 - (16 ÷ (4 + 4)) =

16 ÷ 8

60 - 48 - 2

110

j) 45 - {8+ [1 +(14÷ 7 + 6 x 2)] + 1}=

45 - {8 [+1 +14 ] +1}

45 - {8 .15 +1}

45 - 121

-80
