$$\begin{aligned} \mathtt{2}\mathtt{0}\mathtt{0}\mathtt{0}\\ \mathtt{+\phantom{0}}\mathtt{4}\mathtt{5}\mathtt{6}\mathtt{6}\\ \hline \mathtt{6}\mathtt{5}\mathtt{6}\mathtt{6} \end{aligned}$$

$6$ is the digit in the $10^{0}$ place. $0 \times 10^{0} + 6 \times 10^{0} = 6 \times 10^{0}$.

$6$ is the digit in the $10^{1}$ place. $0 \times 10^{1} + 6 \times 10^{1} = 6 \times 10^{1}$.

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

$6$ is the digit in the $10^{3}$ place. $2 \times 10^{3} + 4 \times 10^{3} = 6 \times 10^{3}$.
