pvf (por favor) me ajuda é para hoje ​

Answer 1

31) 6 × (2 + 7) = 6 × 9 = 54.

32) 7 × (3 + 5) = 7 × 8 = 56.

33) 8 × (10 - 2) = 8 × 8 = 64.

34) (6 + 4) × 2 = 10 × 2 = 20.

35) (6 - 4) × 9 = 2 × 9 = 18.

36) 3 × (15 - 5) = 3 × 10 = 30.

37) (9 - 2) × 4 = 7 × 4 = 28.

38) 24 ÷ (15 - 7) = 24 ÷ 8 = 3.

39) 40 ÷ (8 - 3) = 40 ÷ 5 = 8.

40) 45 ÷ (12 - 9) = 45 ÷ 3 = 15.
