Boolean Operators

Boolean is similar to binary since it has two possible values. The only difference is that in Boolean, True is 1 and False is 0

Relational Operators can work between any two values of the same type known as operands, provided that the type supports such types of operators
Some of these operators include…
- == (equal to)
- != (not equal to)
- (greater than)
- < (less than)
- = (greater than or equal to)
- <= (less than or equal to)
Work on strings and lists too, values at each index is compared in order to determine which one is greater (ex. abg < acd)

Operators that works operand(s) to produce a single boolean result. (ex. and, or, not)
“and” only returns true when both operands around it are true
“or” returns true when at least one of its operands is true
“not” returns true when the boolean after it is false

algorithm - a set of instructions that are designed to accomplish a certain task
selection - the process that determines which parts of an algorithm is being executed based on a condition that is true or false

A conditional is a statement that affects the flow/outcome of a program by executing different statements based on the result of a true or false statement (boolean expression!)
Conditionals appear in almost every programming language because of how important it is for changing the flow of the program
Conditional statements are used by the selection process for a program
One example of a conditional is an if/else statement. If/else statements are used in almost every programming language

Nested Conditional Statements consist of conditional statements within conditional statements
Essentially, one can think of nested conditional statements as an if statement within an if statement.
If Else statements can be put inside of another if else statement
