Respuesta:
a) 15 + 7 - 7 - 9 + 54 -7 = 53
b) 45 - 7 + 10 - 32 + 5 - 7 = 14
c) 6 + 7 + (8 + 7 - 5) + 40 - 18 = 45
d) (6 + 45 + 12 - 8) - (4 + 20 + 56 - 30) = 5
e) 7 + 9 ÷ 3 + 8 × 4 + 15 + 20 ÷ 5 = 61
f) 45 ÷ 9 + 7 - 9 + 6 × 8 + 69 ÷ 3 - 6 = 68
g) 9 + 30 - (7 + 5 × 4) + (5 + 30 ÷ 6 + 12) = 34
h) 8 + (6 × 3 + 5) - (56 ÷ 7 - 5) × 8 = 7
paso a paso:
a) 15 + 7 - 7 - 9 + 54 -7
= 15 - 9 + 47
= 6 + 47
= 53
b) 45 - 7 + 10 - 32 + 5 - 7
= 38 - 22 - 2
= 38 -24
= 14
c) 6 + 7 + (8 + 7 - 5) + 40 - 18
= 6 + 7 + 10 + 40 - 18
= 13 + 50 - 18
= 13 + 32
= 45
d) (6 + 45 + 12 - 8) - (4 + 20 + 56 - 30)
= 55 - 50
= 5
e) 7 + (9 ÷ 3) + (8 × 4) + 15 + (20 ÷ 5)
= 7 + 3 + 32 + 15 + 4
= 10 + 32 + 19
= 42 + 19
= 61
f) (45 ÷ 9) + 7 - 9 + (6 × 8) + (69 ÷ 3) - 6
= 5 + 7 - 9 + 48 + 23 - 6
= 12 + 39 + 17
= 41 + 17
= 68
g) 9 + 30 - (7 + 5 × 4) + (5 + 30 ÷ 6 + 12)
= 39 - (7 + 20) + (5 + 5 + 12)
= 39 - 27 + 22
= 34
h) 8 + (6 × 3 + 5) - (56 ÷ 7 - 5) × 8
= 8 + (18 + 5) - (8 - 5) × 8
= 8 + 23 - 3 × 8
= 31 - 24
= 7
