Long multiplication is a method of multiplying two numbers which are difficult to multiply easily.
For example, we can easily find the product of 55 × 20 by multiplying 55 by 2 and then adding a 0 at the rightmost place of the answer.
55 × 2 = 110 and 55 × 20 = 1100.
But, many a time finding the product is not this easy. At such times we use the long method of multiplication.
