Answer 1

Resposta:

c) 22

d) 43

e) 10

f) 16

g) 58

Explicação passo-a-passo:

25 - [10 - (2 x 3 + 1)]

25 - [10 - (6 + 1)]

25 - [10 - 7]

25 - 3

22

70 - [12 + (5 x 2 - 1) + 6]

70 - [12 + (10 - 1) + 6]

70 - [12 + 9 + 6]

70 - 27

43

8 : 2 + [15 - (4 x 2 + 1)]

8 : 2 + [15 - (8 + 1)]

8 : 2 + [15 - 9]

8 : 2 + 6

4 + 6

10

9 + [4 + 2 x (6 - 4) + (2 + 5)] - 8

9 + [4 + 2 x 2 + 7] - 8

9 + [4 + 4 + 7] - 8

9 + 15 - 8

24 - 8

16

50 + {10 – 2 x [( 6 + 4 : 2 ) - (10 - 3)]}

50 + {10 – 2 x [( 6 + 2 ) - 7]}

50 + {10 – 2 x [8 - 7]}

50 + {10 – 2 x 1}

50 + {10 – 2}

50 + 8

58
