            Multiplication of 2-Digit Numbers by 2-Digit Numbers



            Example : Multiply 65 by 24.





            Step 1 :  Expand 24 i.e. 20 + 4.
                                                                                                  Th    H     T    O
            Step 2 :  Multiply 65 by 4.                                                                       6     5

                          65 × 4 = 260                                                                   ×    2     4


            Step 3 :  Multiply 65 by 20.                                                                 2    6     0
                                                                                                + 1      3    0     0
                          65 × 20 = 1300
                                                                                                   1     5    6     0
            Step 4 :  Add both the products.


                          260 + 1300 = 1560
                                                                                             \ 65 × 24 = 1560
