2.3

The main points in 2.3 are the if, then way of writing a statement. The part after the if is the hypothesis and the part after the then is the conclusion. Not all conditional statements are in if, then form. The other way is very similar to the if, then form but the difference is that there is no if, then just the hypothesis and conclusion by themselves. The truth value of conditional statements is if the hypothesis is true than the conclusion will be true. There are three other kinds of if, then statements. They are converse, inverse and contrapositive. Conditional statements and contrapositive statements are always true and converse and inverse statements can be true or false, it depends on what the statement is saying.
