Logical operators allow programmers to create complex conditional statements by combining two or more simple conditional statements using logical operators like AND, OR, and NOT. This is more efficient than writing multiple separate conditional statements. Logical operators evaluate statements in a certain order - AND statements require both statements to be true, while OR statements require only one to be true. Truth tables can be used to explore the logical values that result from combining statements with different logical operators.

1. Computer Logic

2. Logical Operators
 Logical operators are ways in which
we can create more complex
conditional statements.
 More efficient code
 Computer ranges of values
 A logical operator is formed by
usually combining 2 conditional
statements utilizing
 and
 or
 not

3. Logical Operators
 The computer evaluates the 1st statement and
then the 2nd statement
 Question: Why is this a more efficient way? Think
of the and/or situations separately?
 Fist statement And Second statement
 For a True-response both statements have to be true
 Fist statement Or Second statement
 For a true response only 1 statement has to be true
 They can even include more than 2 conditional
statements. 3, 4, or however many as you like.
 You can work with or’s or and’s in a statement.
 Question: Which Operator takes precedence and
why? Think order of Ops

4. Exercise
 Exploring logical values and truth tables
 Truth Tables Exercise
 Assume p = driving fast q = w/o a seat belt
 Chances of getting a ticket
p q p And q
1 1 1
0 1 0
1 0 0
0 0 0
