definitions
This page provides the means to construct a "shortened" truth
table. That is, it helps you construct a table for one specific assignment
of truth values to a sentence's atomic components.
Directions:
- Begin with a button for problem one.
- Values for atomic values will be randomly generated under these sentences
on the left of the table; rewrite these values under the appropriate atomic
components on the right.
- Move to the sentence you entered and fill in starting with the shortest
sentences (atomic, then negated atomic, then within parentheses, etc.)
- You may enter lower case 't's and 'f's into a field of the table: if your
answer is correct, the lower case will turn to upper when you remove the flashing
cursor from the field (by clicking or TABing).
- If a question mark appears, that means there is a mistake. Correct it or,
if you tried to fill in a value too soon and out of order, come back and correct
it later.
- As usual, keep the table in mind:
| P |
Q |
P&Q |
PvQ |
P>Q |
P=Q |
~P |
| T |

Printing:
After finishing the 10 problems, use the "show and print all finished
problems" button. It will let you print correct problems.

Hints:
- You may move around this truth table form and any form on the Web by using
the "TAB" and "SHIFT-TAB" keys. If the truth value ('t'
or 'f') you entered at a position is correct, it will change to upper case
('T' or 'F') as soon as you move on.
- The Café checks your answer only when you move out of a form field
(by TABing or by clicking outside the field). So, you may enter a 't' somewhere
in the table, move on by TABing, and your answer will be checked.
