$\bar{A}+\bar{B}=\bar{A}\cdot \bar{B}\backslash bar\{A\}+\backslash bar\{B\}=\backslash bar\{A\}\; \backslash cdot\; \backslash bar\{B\}$

$\bar{A}+\bar{B}=\overline{A\cdot B}\backslash bar\{A\}+\backslash bar\{B\}=\backslash overline\{A\; \backslash cdot\; B\}$

$\bar{A}+\bar{B}=\overline{A+B}\backslash bar\{A\}+\backslash bar\{B\}=\backslash overline\{A+B\}$

$\bar{A}+\bar{B}=A\cdot B\backslash bar\{A\}+\backslash bar\{B\}=A\; \backslash cdot\; B$
