Answer
An argument consists of two parts which are called the premises and a conclusion. An argument is called valid argument if conclusion is true whenever the premises are assumed to be true.
Consider the simple statements in the argument with a letter:
\[p\]: I am going.
\[q\]: You are going.
Express the premises and the conclusion symbolically as
I am going if and only if you are not: \[p\leftrightarrow \tilde{\ }q\]
\[\frac{\text{ You are going}\text{.}}{\therefore \text{Im going}\text{.}}\]: \[\frac{q}{\therefore p}\]
Write a symbolic statement of the form:
\[\left[ \left( \text{premise}\ \text{1} \right)\wedge \left( \text{premise}\ \text{2} \right) \right]\to \text{conclusion}\]
The symbolic statement is
\[\left( p\leftrightarrow q \right)\wedge \left( q \right)\to p\]
