Equation 8: (12 + 12 - 3²) × 4 - 23

Equation 8, a seemingly intricate expression, presents a blend of arithmetic operations, exponents, and parentheses. To conquer this equation, we must embark on a step-by-step journey, meticulously applying the order of operations to unveil its solution. Our adventure begins with the parentheses, where we encounter a symphony of addition, subtraction, and exponentiation. Within this enclosed realm, the order of operations dictates that we first address the exponent, transforming 3² into 9. With this transformation complete, we proceed to the addition and subtraction, working from left to right, combining 12 and 12 to reach 24, and then subtracting 9 to arrive at 15. The parentheses, once a realm of complexity, now yield a single, elegant value: 15. This value becomes our key to unlocking the next stage of the equation. We venture beyond the parentheses, encountering multiplication and subtraction. The order of operations guides us to prioritize multiplication, transforming 15 × 4 into 60. With this multiplication complete, we stand at the precipice of the final operation: subtraction. We subtract 23 from 60, and the equation surrenders its solution: 37. Thus, Equation 8, once a puzzle, now stands resolved, its answer revealed through the power of methodical calculation. The solution is 37.

Step-by-step breakdown:

  1. Parentheses: 12 + 12 - 3² = 12 + 12 - 9 = 24 - 9 = 15
  2. Multiplication: 15 × 4 = 60
  3. Subtraction: 60 - 23 = 37

Equation 9: 4³ - 15 × 6 ÷ (32 - 29)²

Equation 9 presents a more intricate challenge, weaving together exponents, multiplication, division, subtraction, and parentheses. To unravel this equation's complexity, we must meticulously adhere to the order of operations, navigating each step with precision. Our expedition commences within the parentheses, where subtraction awaits. We subtract 29 from 32, a simple act that yields the value 3. However, the parentheses hold another secret: an exponent. We square the result, transforming 3 into 9. The parentheses, once a domain of subtraction and exponents, now yield the value 9, a key that unlocks the next stage of our journey. We venture beyond the parentheses, encountering a tapestry of exponents, multiplication, and division. The order of operations guides us to prioritize the exponent, transforming 4³ into 64. With the exponent resolved, we turn our attention to multiplication and division, operations that share equal precedence. We proceed from left to right, first multiplying 15 and 6 to obtain 90, and then dividing 90 by 9 to arrive at 10. With multiplication and division conquered, we stand at the threshold of the final operation: subtraction. We subtract 10 from 64, and the equation surrenders its solution: 54. Thus, Equation 9, once a labyrinth of mathematical operations, now stands resolved, its answer revealed through the power of methodical calculation. The solution is 54.

Step-by-step breakdown:

  1. Parentheses and Exponent: (32 - 29)² = (3)² = 9
  2. Exponent: 4³ = 64
  3. Multiplication and Division (from left to right): 15 × 6 ÷ 9 = 90 ÷ 9 = 10
  4. Subtraction: 64 - 10 = 54

Equation 10: 2 × 11² - 2 × (4 × 7 - 3)

Equation 10 presents a complex interplay of multiplication, exponents, subtraction, and parentheses. To unravel its intricacies, we must meticulously follow the order of operations, navigating each step with precision and clarity. Our expedition begins within the parentheses, where multiplication and subtraction intertwine. The order of operations dictates that we first address the multiplication, transforming 4 × 7 into 28. With this multiplication complete, we proceed to subtraction, subtracting 3 from 28 to arrive at 25. The parentheses, once a realm of multiplication and subtraction, now yield the value 25, a key that unlocks the next stage of our journey. We venture beyond the parentheses, encountering multiplication, exponents, and subtraction. The order of operations guides us to prioritize the exponent, transforming 11² into 121. With the exponent resolved, we turn our attention to multiplication, an operation that appears twice in this equation. We multiply 2 and 121 to obtain 242, and then multiply 2 and 25 to arrive at 50. With multiplication conquered, we stand at the precipice of the final operation: subtraction. We subtract 50 from 242, and the equation surrenders its solution: 192. Thus, Equation 10, once a complex tapestry of mathematical operations, now stands resolved, its answer revealed through the power of methodical calculation. The solution is 192.

Step-by-step breakdown:

  1. Parentheses: 4 × 7 - 3 = 28 - 3 = 25
  2. Exponent: 11² = 121
  3. Multiplication (from left to right): 2 × 121 = 242 and 2 × 25 = 50
  4. Subtraction: 242 - 50 = 192

In this comprehensive exploration of complex equations, we have witnessed the power of methodical problem-solving and the elegance of mathematical principles. By meticulously applying the order of operations and dissecting each equation into manageable steps, we have successfully unraveled their solutions.
