Modus Ponens, Modus Tollens, & Syllogisms Crap....

Oook so today in class we discussed deductive logic, syllogisms, modus ponens, modus tollens etc...


Deductive Logic is basically made up of a Syllogism, Modus Ponens, and Modus Tollens.
An example of a Syllogism would be:

All girls PMS.
Erika is a girl.
Erika PMS'.


In the Syllogism it would be in an order like
A = B
B = C
C = A


All girls PMS.
Erika is a girl.
Erika PMS'.


PMS = A
Girl = B
Erika = C


confusing much? yes.




Modus Ponens is somehow a little easier to understand (well for me).

Example:

If I shoot my mom, ill go to jail.
I shot my mom therefore, I will go to jail.

its kind of like a cause and effect thing....
It's like if something happens then something else will happen as a result.
This is very hard fore me to explain...ehhh.




Modus Tollens is just about the same as Modus Ponens except you're just making it negative.

Example:

If I'm pregnant, then I had sex.
I'm not pregnant therefore, i didn't have sex.




get me?




it was possible to click in my head fore me. eek.
