 +Truth tables:
 +first columns : True/False values of the variables, such as p, q, or p' or ~p for inverse values. Next columns are logic combinations of the variables
 +
 +| p | q | p ⋂ q | p ⋃ q| p => q |
 +| T | T | T | T | T |
 +| T | F | F | T | F |
 +| F | T | F | T | T |
 +| F | F | F | F | T |

 +p => q means condition p implies condition q. If p is true, then an implication can be drawn or not, depending on q. If p is false, then an implication cannot be ruled out, regardless of q, so it is left as true.
