The key difference when adding decimals compared to whole numbers lies in the alignment of the decimal points. When adding decimals, you must ensure that the numbers are lined up according to their decimal points, which makes it easier to keep track of the place values (tenths, hundredths, etc.). This is important because it helps maintain the accuracy of the sum and prevents errors that could arise from misplacing a digit, especially when dealing with fractional values. Proper alignment ensures you add each place value correctly and get an accurate result, which is crucial in many real-life applications like financial calculations, measurements, and data analysis.
