                    Multiplication of Large Numbers by 2-Digit, 3-Digit                            Top Tip
                    and 4-Digit Numbers (Long Multiplication Method)                           We usually write
                                                                                              the bigger number
                    Long multiplication is a method used for multiplying numbers            as multiplicand and the
                    larger than 10.                                                           smaller number as
