1 Chapter 3 section 3

2 Conditional pqpqpq TTT TFF FTT FFT The p is called the hypothesis and the q is called the conclusion.

3 Examples I am an owner of a small factory, a rush order must be filled out by Monday. I approach you with this generous offer: p = You work for me on Saturday. q = I’ll give you a $100 bonus. If you work for me on Sat., then I’ll will give you a $100 bonus.

4 Case 1 You come to work and you receive the bonus. If p is true and q is true. Case 2 You come to work and you don’t receive the bonus. If p is true then q is false.

5 Case 3 You don’t come to work, but I will give you a bonus. If p is false, then q is true. Case 4 You don’t come to work and you don’t receive the bonus. If p is false, then q is false.

6 Case 3 explaination Do you understand why? In mathematics we tend to use if…then statements a little different. Do not read more into my statement. You do not expect to get the bonus if you did not come to work because that is your experience. I never said that. You are assuming this condition.

8 Biconditional Iff- if and only if. It means that two statements say the same thing.

9 Examples x+3 = 7 iff x = 4 Today is Monday iff tomorrow is Tuesday.
