I have shown how easy and fast it is to multiply numbers using a base number. However, these bases tend to be factors of 10 or 100, etc. And if the numbers we are dealing with are not close to these factors, using bases such 20, 30 or 40 is desirable.
HINT: Using any number is possible as a base! Wait for the next streaming.
NOTE: These methods are derived from the Hindu scriptures, particularly the Vedas. For further info, check out Swami Bharati Krishna Tirtha's Vedic mathematics.
