3.2.2: Conditional Statements
3.2.2 Learning Objectives. In logic a statement is something that is either true or false. A statement like 3 < 5 is true; a statement like "a rat is a fish" is false. A statement like " x < 5 x < 5 " is true for some values of x x and false for others. When an action is taken or not depending on the value of a statement, it forms a ...
2.11: If Then Statements
The conclusion is the result of a hypothesis. Figure 2.11.1 2.11. 1. If-then statements might not always be written in the "if-then" form. Here are some examples of conditional statements: Statement 1: If you work overtime, then you'll be paid time-and-a-half. Statement 2: I'll wash the car if the weather is nice.
1.1: Statements and Conditional Statements
Using this as a guide, we define the conditional statement P → Q to be false only when P is true and Q is false, that is, only when the hypothesis is true and the conclusion is false. In all other cases, P → Q is true. This is summarized in Table 1.1, which is called a truth table for the conditional statement P → Q.
3.2.2.1: Exercises
Conditional Statements. Consider the statement "If you are under age 17, then you cannot attend this movie." Identify the two simpler statements used in this conditional statement. Write the converse. Write the inverse. Write the contrapositive. Assume that the statement "If you swear, then you will get your mouth washed out with soap ...

The _____ of a conditional statement is the phrase immediately following the word then. Conclusion A result or judgment based on reasoning, research, calculation, etc.
Conditional Statements
A conditional statement, as we've seen, has the form "if p then , q, " and we use the connective . p → q. As many mathematical statements are in the form of a conditional, it is important to keep in mind how to determine if a conditional statement is true or false. A conditional, , p → q, is TRUE if you can show that whenever p is true ...

To find the converse of a conditional statement, you must switch the. NOT ALL CONVERSES WILL BE TRUE!! An example for which the hypothesis is true, but the conclusion is false. EXAMPLES. = −5, h. = 5. 4 + 3 = 19, h = 4. BICONDITIONAL. If a conditional statement and its converse are both true, they can be.

Choose the correct forms of the second and third conditionals to complete the sentences. 1 If he changed would change would have changed jobs, he would be a lot happier. 2 If I were you, I told 'd tell had told her that I love her. 3 Even if he would ask asked had asked them, they wouldn't have agreed to come. 4 If she hadn't threatened him ...
Conditional Statements (15+ Examples in Geometry)
Example. Conditional Statement: "If today is Wednesday, then yesterday was Tuesday.". Hypothesis: "If today is Wednesday" so our conclusion must follow "Then yesterday was Tuesday.". So the converse is found by rearranging the hypothesis and conclusion, as Math Planet accurately states. Converse: "If yesterday was Tuesday, then ...
17.3: Conditional Statements
As mentioned earlier, conditional statements are commonly used in spreadsheet applications like Excel or Google Sheets. In Excel, you can enter an expression like. \ (=\mathrm {IF}\left (\mathrm {A} 1<2000, \mathrm {A} 1+1, \mathrm {A} 1 \times 2\right)\) Notice that after the IF, there are three parts. The first part is the condition, and the ...
2.7: Conditionals
All of these conditional statements are symbolized the same way, namely R ⊃ G. The antecedent of a conditional statement always lays down what logicians call a sufficient condition. A sufficient condition is a condition that suffices for some other condition to obtain. To say that x is a sufficient condition for y is to say that any time x is ...

Conditionals
They describe the result of something that might happen (in the present or future) or might have happened but didn't (in the past) . They are made using different English verb tenses. Download my infographic! There are four main kinds of conditionals: If you heat water to 100 degrees, it boils.
3.1 Statements, Negations, and Quantified Statements 3.2 Compound
Use a letter to represent each sample statement in the argument. Express the premises and the conclusion symbolically. Write a symbolic conditional statement of the form premise 1 ∧ premise 2 ∧ ⋯ ∧ premise n → conclusion where is the number of premises. Construct a truth table for the conditional statement in Step 3.
