Boolean Algebra

Any equation must be within the <math> </math> tags. For Boolean alegbra the main issue is how to negate a term like:

[math] \overline{a}[/math] or [math] \overline{\overline{a}+b}[/math]

this can be done by adding the following around any term you wish to negate.:

\overline{}  

[math] \overline{a}[/math]

is

\overline{a}

[math] \overline{\overline{a}+b}[/math]

is

\overline{\overline{a}+b}.
