Yes, When Adding and Subtracting decimals you should line up the decimals. You need to keep each place value in the same column, the same as when you add whole numbers you keep the ones column lined up, same for the tens, etc. Lining up the decimal points makes sure that the tenths column is kept together, same for the hundredths, and so on.

How is adding decimals similar to adding whole numbers?
Adding whole numbers is the addition of decimals where the decimal part is zero; in both cases the digits are place value aligned meaning that the decimal points, which lies between the units (or ones) and tenths columns, are aligned - in the whole number the decimal point is "hiding" at the end.
