Is my truth table correct?

Question

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

Answer 1

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.
