My table on this link

I am not really sure about the symbols. does the over line mean negation?does the asterisk mean conjunction?if there's mistake, i'd be grateful if someone could upload the corrected table. thanks

  • Looks ok to me. Your understanding of the Line above (Negate) and Asterisk is correct. – Mike Nov 11 '16 at 14:23

The symbols in corresponding standard notation are: \begin{align*}&+\quad \text{corresponds to}\quad \lor\quad, \quad\text{ "or"}\\ &* \quad \text{corresponds to}\quad \land\quad, \quad\text{ "and"}\\ &\overline{\cdot}\quad \text{corresponds to}\quad \lnot\quad, \quad\text{ "not"} \end{align*} Besides that, the table looks correct.

  • I'd avoid using tilde (~) here because this is not infrequently used to mean logical negation ("not"). – hardmath Nov 11 '16 at 14:25
