2-3 Conditional Statements Vocab: Conditional Statement: An if-then statement Hypothesis: An educated guess (the if part) Conclusion: The result of a hypothesis (the then part)

Identifying the Hypothesis and Conclusion Ex 1: If the forecast is rain, then I will take an umbrella Hypothesis: The forecast is rain Conclusion: I will take an umbrella Ex 2: A number is divisible by 10 if the number ends in 0

Writing in If-Then Form Ex 3: Identify the hypothesis and conclusion, write in if-then form, then give a truth value: A mammal is a warm blooded animal. Dividing an integer by an integer, the result is always an integer

Related Conditionals Conditional: if p then q Converse: if q then p Inverse: if ~p then ~q Contrapositive: if ~q then ~p Ex 4: Conditional: If it’s lunchtime, then you ate cheesesticks.
