Let p: the book is interesting and q: the book has pictures. The notation p ∧ q represents the statement “The book is interestin
MatroZZZ [7]
This is a Logic Problem. So we need to use operators to solve this problem. There are several operators in logic. Operators can be <em>monadic or dyadic</em>. A <em>monadic operator</em> operates on a single simple statement. Other operators will all be <em>dyadic operators </em>because they operate on two simple statements. 

So we have the following simple statements:

p: the book is interesting
q: the book has pictures

Thus, let's solve each notation.

First. p ∧ q

<u>Conjunction operator.</u> <span>The conjunction operator creates a compound statement such that in order for the whole statement to be true, <em>each simple statement must be true. </em>

</span><u>Symbol:</u> & (also ∧)
<u>Parts of conjunction:</u> <span>Two simple statements joined by the conjunction symbol. 
</span>
<u>Answer:</u>

<span>p ∧ q: The book is interesting and the book has pictures.

</span>Second. p ↔ q

<u>Bi-conditional operator:</u> The bi-conditional operator creates a compound statement such that in order for the whole statement to be true <em>each simple statement has to have the same truth value.</em> 

<u>Symbol:</u> ↔ 
<u>Parts of bi-conditional:</u> Two simple statements joined by the bi-conditional symbol. 

<u>Answer:</u>

p ↔ q: The book is interesting if and only if the book has pictures.

Third. p ∨ q

<u>Disjunction operator:</u> The disjunction operator creates a compound statement that is <em>true if either simple statement is true but false if both simple statements are false.</em>

<u>Symbol:</u> ∨
<u>Parts of disjunction: </u>Two simple statements joined by the disjunction symbol

<u>Answer:</u>

p ∨ q: The book is interesting or the book has pictures.

Fourth. p → q

<u>Conditional operator:</u> T<span>he conditional operator creates a compound statement that sets up a condition for something to be true. <em>If the condition is met, the statement is true.</em>
</span>
<u>Symbol:</u> →
<u>Parts of conditional:</u> <span>Two simple statements joined by the conditional symbol. The first simple statement in a conditional is called the </span><em>antecedent</em><span> and the second simple statement is called the </span><em>consequent</em><span>.</span>

<u>Answer:</u>

p → q: If the book is interesting then the book has pictures.
