$$20 + 76=96$$

$$\begin{aligned} \mathtt{2}\mathtt{0}\\ \mathtt{+\phantom{0}}\mathtt{7}\mathtt{6}\\ \hline \mathtt{9}\mathtt{6} \end{aligned}$$

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

$9$ is the digit in the $10^{1}$ place. $2 \times 10^{1} + 7 \times 10^{1} = 9 \times 10^{1}$.
