Add: \( 9.18+27.01+0.53+4.25= \)

To make the addition process easier, you can group the numbers. For instance, adding \( 9.18 \) and \( 0.53 \) gives you \( 9.71 \), while \( 27.01 \) and \( 4.25 \) totals \( 31.26 \). Then, simply add those two results together: \( 9.71 + 31.26 = 40.97 \). Voilà! One common mistake when adding decimals is misaligning the decimal points. Always check to stack your numbers properly, ensuring that the decimal points are in line. This helps avoid mix-ups, especially when dealing with more complex calculations and decimal places!
