About Multiplication:

We can easily multiply single digit whole numbers without the use of a pencil and paper. When we start multiplying multi-digit whole numbers, it becomes more difficult to perform the operation in one’s head. Generally we multiply two or more multi-digit whole numbers using vertical multiplication.
