Carrying Over: It makes it easier to carry over numbers. If you’re adding and the total of a column is bigger than , you can simply move the extra to the next column without worrying.
Keeping Decimal Places: Lining up the decimals makes sure you keep the same number of decimal places in your final answer. You’ll always know how to round or when to stop because it shows how many important digits you started with.
In short, aligning decimal points helps you make fewer mistakes and feel more confident with decimals. It makes math way less scary!
