What is BODMAS . how to use with example .

                                     What is BODMAS

BODMAS rule explain the order of different operations (such as ➗ , ✖ , ➕, ➖) and bracket to simplify a mathematical expression. 

                       BODMAS means -

                 B - Bracket (it is of four types )

                                                          

                           1) Vincolumn or bar

                            2) Parantheses or round bracket ( )

                                  E.g (3+2-1) 

                             3) Braces or curly bracket⦃  ⦄

                             4) square bracket or Box brackrt ⦍  ⦎

                    O - of (power of percentage or multiply)

                    D - Division (➗)

                    M - multiplication (✖)

                     A - Addition (➕)

                     S - Subtraction (➖)

First solve ' bracket ' ( in above order), then ' of ' ,then performs operation in sequence i.e. , ' Division ' - first, ' Multiplication ' - second,' Addition ' - third, and 'Subtraction' - fourth . 

What is Factor and Prime factor with example

                   WHAT IS FACTOR AND PRIME FACTOR 

1) Factor : A factor is a small number which divides exactly a bigger number. 

      for example : 

                               18 = 2 ✖ 3 ✖ 3 

                                        |___|____|____________ 2 and 3 are factor of 18 .

                                64 = 2 ✖ 2 ✖ 2 ✖ 2 ✖ 2 ✖ 2 

                                         |___|___|___|____|___|____________ 2 is factor of 64 .

                                 45 = 3 ✖ 3 ✖ 5 

                                           |___|___|______________ 3 and 5 are factor of 45 .

2) Prime factor : If the factor of a given number are prime number then they are called prime factor .

            For example : 

                                          39 =3 ✖ 13 

                                                  |____|_______________ 3 and 13 are prime factor of 39 . 

                                          57 = 3 ✖ 19 

                                                   |____|_______________ 3and 19 are prime factor of 57.
