10000 1 2 = 33 100001_2=33 10010 1 2 = 37 100101_2=37

⇒ 10000 1 2 + 10010 1 2 = 70 = 100011 0 2 \Rightarrow 100001_2+100101_2=70=\boxed{1000110_2}

Binary addition follows the same rule as integer addition

1 1 1 0 0 0 0 1 + 1 0 0 1 0 1 1 0 0 0 1 1 0 ‾ \begin{matrix} 1 & & & & & 1 & \\ & 1 & 0 & 0 & 0 & 0 & 1 \\ + & 1 & 0 & 0 & 1 & 0 & 1 \end{matrix}\\ \overline { \begin{matrix} 1 & 0 & 0 & 0 & 1 & 1 & 0 \end{matrix} }
