I guess this kinda stuff confuses me because of the

assumptions.

*> Now let us consider whether her father is telling
*

*> the truth. Suppose
*

*> Sally is good and he does take her. In this case
*

*> his statement is true.

Are we using symbology to analyze someone's statement?

In boolean algebra, we don't care what the values are.

We use symbology to define the behavior of a system

described with a boolean algebra statement.

Here it appears we are implying:

1. That there is a statement.

2. That there is an expression.

3. That the <IF> statement attempts to formalize

the relationship between a statement and an

expression and express them with a second

statement.

This is much different from the use of logic to define

a logic circuit. The final expression is the result of

an input expression and a statement (algebraic

formula), resulting in an output statement.

My biggest problem in understanding this kind of

language or dialog is the difference I just described.

*> are good." This means that if she is good, he will
*

*> take her, but if
*

*> she is bad, he will not take her. The truth table

*

*>

*> AB:C
*

*> 11 1
*

*> 10 0
*

*> 01 0
*

*> 00 1
*
