When we add with multi-digit numbers with decimals, we start with the numbers furthest to the right and work our way towards the left.

Add the numbers in the hundredths place:

\(\displaystyle {6+7=13}\)

Because this sum is greater than 9, we write the 3 from the ones place and carry the 1 from the tens place over to the left. Your work should look something like this:

\(\displaystyle \begin{array}{r}\overset{\ ~}{3} \overset{\ ~}{3.}\overset{\ 1}{0}6\\ + \overset{\ ~ }{4}\overset{\ ~ }{5.}\overset{ }{4} \overset{~\ }{7} \\ \hline \space{} \, \space{\, } \space{\, }3\end{array}\)

Add the numbers in the tenths place:

\(\displaystyle {0+4+1=5}\)

Your work should look something like this:

*Notice that the decimal moves directly down when we are adding decimal numbers.
