Answer 1

64 + 5 = 69

75 - 4 = 71

84 + 3 = 87

3 + 52 = 55

88 - 4 = 84

73 + 4 = 77

87 - 5 = 82

2 + 47 = 49

52 + 10 = 62

39 - 20 = 19

98 - 50 = 48

75 - 2 = 73

12 + (20 + 30) - 2 = 12 + 50 - 2 = 62 - 2 = 60

4 + 6 + (45 - 5) = 10 + 40 = 50

65 - 30 + (20 - 10) = 35 + 10 = 45

(97 - 7) - (35 - 5) = 90 - 30 = 60

Answer 2

To solve the given expression, let's break it down step by step:

1. Start with the addition and subtraction operations within parentheses: (20 + 30) = 50 (45 - 5) = 40 (20 - 10(97 - 7)) = (20 - 10 * 90) = (20 - 900) = -880 (35 - 5) = 30

   The expression now becomes: 64 + 575 - 484 + 33 + 5288 - 473 + 487 - 52 + 4752 + 1039 - 2098 - 5075 - 212 + 50 - 24 + 6 + (40 * 65) - 30 + (-880) - 30

2. Perform multiplication inside the expression: (40 * 65) = 2600

   The expression now becomes: 64 + 575 - 484 + 33 + 5288 - 473 + 487 - 52 + 4752 + 1039 - 2098 - 5075 - 212 + 50 - 24 + 6 + 2600 - 30 + (-880) - 30

3. Continue with the addition and subtraction operations: 64 + 575 - 484 + 33 + 5288 - 473 + 487 - 52 + 4752 + 1039 - 2098 - 5075 - 212 + 50 - 24 + 6 + 2600 - 30 + (-880) - 30 = 8484

Therefore, the value of the given expression is 8484.
