Securing Accuracy in Addition: Understanding the Total Mistake — Why 14.013 Is Not Equal to 15 When performing basic arithmetic operations, precision matters — even in simple sums. A common misconception arises from incorrectly rounding or miscalculating decimal additions. Consider the equation:
Total = 3.387 + 4.852 + 6.774 = 14.013 ≈ 15? At first glance, the addition looks correct: 3.387 + 4.852 = 8.239, and then 8.239 + 6.774 = 14.013. However, rounding 14.013 to 15 involves a significant rounding error and misrepresentation of value. Let’s break down why this approximation is misleading and how proper calculation maintains accuracy. ### Why Rounding to 15 Is a Mistake
