Rule of Distribution/Conjunction Distributes over Disjunction/Left Distributive/Formulation 2

Theorem
The conjunction operator is left distributive over the disjunction operator:
 * $\vdash \left({p \land \left({q \lor r}\right)}\right) \iff \left({\left({p \land q}\right) \lor \left({p \land r}\right)}\right)$
