Quick Six Times (II)

As per the method learned in the article Quick Six Times (I) , as a first step we find out five times 6582. .

In this case we need to take care of the remainder that we get after dividing the digit 5 by 2. As you can see in the calculations shown here we have accounted for the remainder by adding 5 to the quotient of the next digit's (which is 8) division by 2.

Thus, five times 6582 is 32910. In order to obtain six times 6582 we now follow Step II. In this step we add 6582 to '5 times 6582. We do this systematically writing both these addends one below the other. .

This systematic addition helps us to understand the place where we need to add '5' for the remainder of the "odd digit". You can see that we added '5' to the odd digit "5" itself. Thus, we will always "add 5" to the odd digit in the number along with half of the digit to its left and carry, if any. Initially we may write 5 above the odd digits in the number as a reminder. With enough practice we may add 5 to the odd digit without writing 5 above it.

Let us now write six times 6582 in one step. We start calculations by writing 6582 as *65820. .

Let us try finding six times 3548. We start calculating by writing 3548 as *35480. We also write '5' above the odd digits 3 and 5 of 3548. This is a reminder for adding 5 to the odd digits along with half of the left-digit and the carry, if any. .

Now find out six times of the following numbers using one step mechanical method discussed in this article. .
