This comprehensive guide aims to unravel the calculation, providing a step-by-step explanation and exploring the underlying mathematical principles.

Demystifying the Order of Operations

The cornerstone of any mathematical calculation lies in the order of operations, a set of rules dictating the sequence in which operations must be performed to ensure accuracy. The acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right), serves as a handy mnemonic for remembering the order. In the given expression, we encounter multiplication and division. According to PEMDAS, multiplication and division hold equal precedence and are performed from left to right. Therefore, we must first address the multiplication operation before proceeding with the division. Understanding the order of operations is paramount to solving mathematical problems correctly. Without adhering to these rules, the outcome of calculations can be skewed, leading to inaccurate results. In this specific calculation, prioritizing multiplication before division ensures that we are adhering to the established mathematical principles, paving the way for a correct solution. By adhering to the order of operations, we establish a clear and logical path towards solving mathematical problems, ensuring accuracy and consistency in our results. This foundational understanding is crucial not only for basic calculations but also for more complex mathematical equations and formulas.

Step-by-Step Breakdown of the Calculation

Step 1: Multiplying 12 by 24

Our initial task involves multiplying 12 by 24. This can be approached in a couple of ways: manually or with the aid of a calculator. To perform the multiplication manually, we can break it down into smaller steps. Multiplying 12 by 4 yields 48, and multiplying 12 by 20 (which is 2 tens) yields 240. Adding these two results (48 + 240) gives us 288. Alternatively, using a calculator, we directly obtain the product of 12 and 24 as 288. Thus, the first step in our calculation reveals that 12 multiplied by 24 equals 288. This foundational step sets the stage for the next operation, which is dividing this product by 124. Accurate multiplication is crucial in this process, as any error in this step will propagate through the rest of the calculation. Whether performed manually or with a calculator, ensuring the correctness of this initial multiplication is essential for obtaining the final accurate result. This step exemplifies the importance of precision in mathematical calculations, where each operation builds upon the previous one, and accuracy at every stage is paramount.

Step 2: Dividing 288 by 124

Having determined that 12 multiplied by 24 equals 288, our next step is to divide 288 by 124. This division can be performed either manually using long division or with the assistance of a calculator. When performing long division, we find that 124 goes into 288 two times, resulting in 248. Subtracting 248 from 288 leaves us with a remainder of 40. To express the result as a decimal, we can add a decimal point and a zero to the dividend (288), making it 288.0. We then bring down the zero, making the remainder 400. Now, 124 goes into 400 three times, yielding 372. Subtracting 372 from 400 gives us a remainder of 28. We can continue this process to obtain further decimal places, but for practical purposes, we can round the result to two decimal places. Using a calculator, we find that 288 divided by 124 is approximately 2.32. This division step demonstrates the process of splitting a quantity (288) into equal parts (124), resulting in a quotient that represents how many times the divisor (124) fits into the dividend (288). The remainder, in this case, indicates the portion of the dividend that is left over after the division is performed. The quotient obtained from this division, whether calculated manually or with a calculator, is a crucial component in understanding the relationship between the numbers involved and arriving at the final solution.

The Final Result: Approximately 2.32

After completing the multiplication and division operations, we arrive at the final result: approximately 2.32. This value represents the outcome of the calculation (12 × 24) / 124. It's essential to recognize that this result is an approximation due to the decimal nature of the division. In certain contexts, rounding the result to a specific number of decimal places may be necessary or appropriate. The final result, 2.32, provides a concise answer to the initial mathematical expression, demonstrating the culmination of the step-by-step calculation process. This numerical value serves as a tangible outcome, representing the quantitative relationship between the numbers involved in the expression. Understanding the significance of this final result allows for its application in various contexts, whether it be in practical problem-solving, scientific analysis, or mathematical modeling. The precision of this final result, determined through careful calculation and rounding, ensures its accuracy and reliability in diverse applications.

Alternative Approaches and Simplifications

While the step-by-step approach provides a clear understanding of the calculation, alternative methods can streamline the process. One such approach involves simplifying the expression before performing the calculations. In this case, we can observe that both 12 and 124 share a common factor of 4. Dividing both numbers by 4, we get 3 and 31, respectively. Therefore, the expression can be rewritten as (3 × 24) / 31. This simplification reduces the magnitude of the numbers involved, making the calculation easier to manage. Multiplying 3 by 24 yields 72, and dividing 72 by 31 gives us approximately 2.32, the same result as before. This alternative approach demonstrates the power of simplification in mathematics, where complex calculations can be transformed into more manageable ones through strategic manipulation. By identifying common factors and reducing numbers, we can often arrive at the same solution with less effort and potential for error. This concept of simplification is a valuable tool in mathematical problem-solving, allowing for efficiency and accuracy in calculations.
