Short Truth Tables..

Technically, it’s not fuzzy logic — but, the image is fun…

The point of a short truth table is to figure out if the premises of an argument CAN be ALL true while the conclusion CAN be false.

Solving them is not quite that simple, but it can be.

The challenge students have with them is that they get to PICK the assignment of truth values for the variables that could make the argument invalid (true premises and a false conclusion) — this kind of stumps them, because they are working backwards from what they need to assign…

We’re mostly doing this so that the students who didn’t do well on the quiz we had before break can get caught up.  It’s a nice diversion I have often included earlier in the semester…  we’ll do some of it, then get back to proofs soon enough.
