Square and Multiplication of "n" number of 1

The conventional approach is lengthy and time taking in term of calculation. But why we need to spent even couple of seconds when we just give the right answer in just counting the numbers.

In this Vedic Math trick we just need to count how many times digit 1 is repeating itself and write counting from 123..... till 1 repeats itself in problem and then reverse the counting, for example what is square of 111. Convetional method is given below but from Vedic Mathematics we will just write answer i.e, 12321.
