Add the following binary numbers:

(10111101)₂ + (1101101)₂

$\begin{matrix} & & \overset{1}{1} & \overset{1}{0} & \overset{1}{1} & \overset{1}{1} & \overset{1}{1} & 1 & \overset{1}{0} & 1 \ + & & & 1 & 1 & 0 & 1 & 1 & 0 & 1 \ \hline & \bold{1} & \bold{0} & \bold{0} & \bold{1} & \bold{0} & \bold{1} & \bold{0} & \bold{1} & \bold{0} \end{matrix}$

Therefore, (10111101)₂ + (1101101)₂ = (100101010)₂
