    COMPARISON OPERATORS
                     These operators are used to compare two values with the given set of operators. When two values
                     are compared by using these operators, the result is either True or False. Some comparison
                     operators are = (equal to), > (greater than), < (less than), >= (greater than equal to), <= (less than
                     equal to) and <> (not equal to).

                     REFERENCE OPERATORS

                     These operators are used to combine a range of cells for calculations. Some reference operators
                     are colon(:) (range operator), comma(,)  (union operator),  space  (intersection  operator).
                     Range operator produces one reference to all the cells between two references. Union operator
                     combines multiple references into one reference. Intersection operator produces a reference to
                     cells common to the two references.

                               OPERATORS PRECEDENCE

                     In  a numeric  formula, the  results  of the  formula are calculated  based  on the  given order of
                     precedence:

                       1  Colon (:), single space, comma (,)             2  Percentage (%)

                       3  Exponent (^)                                   4  Multiplication (*) and Division (/)

                       5  Addition (+) and Subtraction (-)               6   Comparison Operators (=, <, >, <=, >=, <>)

                               WAYS TO ENTER A FORMULA IN EXCEL 2021

                     We can enter a formula in two ways:

                     ENTER A FORMULA DIRECTLY INTO THE CELL

                     Enter a formula into the cell after typing an equals sign. Now, press the Enter key to see the result
                     of the formula in the cell.

                     ENTER FORMULA IN THE FORMULA BAR
                     Select the cell and enter the formula in the Formula bar after typing an equal to sign. Now press
                     the Enter key to see the result.

                                                                                     Formulas and Functions in Excel 2021  17
