$$\begin{aligned} \phantom{0}\mathtt{3}\mathtt{2}\\ \mathtt{+\phantom{0}}\mathtt{4}\mathtt{4}\mathtt{5}\\ \hline \mathtt{4}\mathtt{7}\mathtt{7} \end{aligned}$$

$7$ is the digit in the $10^{0}$ place. $2 \times 10^{0} + 5 \times 10^{0} = 7 \times 10^{0}$.

$7$ is the digit in the $10^{1}$ place. $3 \times 10^{1} + 4 \times 10^{1} = 7 \times 10^{1}$.

$4$ is the digit in the $10^{2}$ place. $0 \times 10^{2} + 4 \times 10^{2} = 4 \times 10^{2}$.
