**G.1 a,b,c LOGIC**

Students use deductive reasoning to construct and judge the validity of a logical argument consisting of a set of premises and a conclusion. This will include:

a) identifying the converse, inverse, and contrapositive of a conditional statement

b) translating a short verbal argument into symbolic form

c) determining the validity of a logical argument

Please review this material with the following material:

. Use chain reasoning to make a logical conclusion given a set of statements.
