12+27-27=12

9+24-12+7=28

18+18-24=12

15+21-13=23

Answer 2

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

Step 1: Evaluate expressions within parentheses.

• (15+9) = 24
• (6+15) = 21
• (2×7+12) = 26
• (82-79) = 3

The expression becomes: 3×4 + 9×3 - 24 : 8×9 + (50-23) : 3 + 8×3 - 6×2 + 21 : 3 + 3×6 + 9×2 - 26 : 6×5 + (5×3 - 3×2 + 18 : 3) + 3×7 - 13

Step 2: Evaluate divisions and multiplications from left to right.

• 24 : 8 = 3
• 3×9 = 27
• 21 : 3 = 7
• 3×6 = 18
• 9×2 = 18
• 26 : 6 = 4
• 5×3 = 15
• 3×2 = 6
• 18 : 3 = 6
• 15 - 6 + 6 = 15
• 3×7 = 21

The expression now becomes: 3×4 + 27 - 3×9 + 7 + 8×3 - 6×2 + 21 + 18 + 18 - 4×5 + 15 + 3×7 - 13

Step 3: Perform additions and subtractions from left to right.

• 3×4 = 12
• 27 - 27 = 0
• 0 + 7 = 7
• 7 + 24 = 31
• 31 + 18 = 49
• 49 + 18 = 67
• 67 - 20 = 47
• 47 + 15 = 62
• 62 + 21 = 83
• 83 - 13 = 70

Therefore, the final result of the expression is 70.
