  1. Variables
    1. A Variable is a piece of data which can be changed, there are data types that contain certain types of data.
      1. Data Types
        1. String
          1. An ordered array of alpha-numeric text
          2. Integer
            1. – A number without decimals
            2. Character
              1. A single piece of alpha-numeric text
              2. Boolean
                1. A data type with only two possible values
                2. Real (Decimal)
                  1. A number with decimals
              3. Scoping
                1. A variables scope refers to where the variable can be accessed and modified.
                  1. Scopes
                    1. Local Scope
                      1. When a variable can be read and modified only within the procedure in which it is declared.
                      2. Module Scope
                        1. Procedures that are in the same module can be read and modify that variable when it’s declared
                        2. Project Scope
                          1. If a variable is in project scope the variable can be read and modified within the same program and project.
                      3. Selection
                        1. An IF statement is a conditional statement and is a type of selection, it will only run parts of the program if the Boolean is True.
                          1. Operators
                            1. ==
                              1. Checks if the values for the operands are equal or not;
