I found this first order logic exercise on Wolfram.
#1 Download Wolfram’s CDF player
-1 The download on their site did not work for me, so I downloaded here from Softpedia.
-2 You will download an .exe file. When it arrives on your personal computer, simply click on the link and it will install as a Program. It takes a little time to install. Big beastie to allow you to view interactive documents.
#2 Now read whatever you want on Wolfram’s Demonstrations
-1 Find the demonstration that interests you. In this case, try this demo for practicing first order logic, also known as predicate calculus..
-2 Click on “Download Demonstration as CDF” at top right and it should open. If not, try firing up Wolfram first from your Start/Programs.
#3 Practice your first order logic
-1 Choose how many objects to play with,
-2 Start at equation number 1.
-3 Move objects around to change the truth value from true to false and v.v
It won’t do your homework for you but it might take the edge off the confusion.
