Some points must be kept in mind while creating a formula:
                     A formula must always begin with an equal (=) sign.

                     Operators must be included to direct the operation.
                     The data can be either numbers or cell addresses.

                           A formula can contain a maximum of 8,192 characters in length.             FACT






                            OPERATORS IN EXCEL 2021

                  Operators are the symbols that are used to perform calculations on the elements of a formula.
                  There are three different types of operators: Arithmetic, Comparison and Reference.

                  ARITHMETIC OPERATORS

                  These operators  perform basic  mathematical  operations.  Some  arithmetic  operators  are:
                  +(addition), -(subtraction), *(multiplication), /(division) and ^(exponential).

                  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 (=, <, >, <=, >=, <>)
