How to Multiply with base of 1000 – Vedic Multiplication – Lesson Four

What we have done so for? Multiply with base of 100, Multiply with base of 10. Now, we learn how to multiply with base of 1000.
Let’s take first example.
Example 1 .Multiply 787 by 998
Deviation of 998 is –002, and Deviation of 787 is –213.
787    -213 
 
998    -002
(787-002) or (998-213) | (213x2)
Solving above, we get
787   -213 
 
998   -002
785 | 426
Hence, 787x998 = 785426
Let's take another example when right-hand-side contains two digits.
Example 2. Multiply 995 by 987
Deviation of 995 is –005, and Deviation of 987 is –013.
987    -013 
 
995    -005
(987-005) or (995-013) | (13x5)
Solving above, we get
987   -013 
 
995   -005
982 | 065
As I already explained in previous post that how many Zeros(0) a base will have that many digits right side will contain. Here base is 1000, so it will contain 3 digits on the left side.
Hence, 987x995 = 982065
Now, another example when we got carry on right hand side. Example 3 .Multiply 770 by 990
Deviation of 990 is –010, and Deviation of 770 is –230.
770    -230  
 
990    -010
(770-010) or (990-230) | (230x10)
Solving above, we get
770   -230  
 
990   -010
760 | 2300
Here, we get carry 2, simply add it to left side as we do in natural addition.
Hence, 770x990 = 762300
In this post I just focus on examples. If you not able to understand yet, you can check the previous post. Where I explained full step by step methods.

Digital roots or Digital Sum of Numbers

The word Digit means the single figure numbers; the numbers from 1 to 9 and zero Digital Root or Digital Sum of a number : is the remainder when the number is divided by 9. So for 31, the remainder is 4 because 31/ 9 = 3 remainder 4. The digital root is also 4. The digital root can also be obtained by summing the digits of the number.

In the last lesson of Vedic Multiplication Methods , I mean here that in my last post I have explained the step-by-step procedure of Vedic Multiplication Methods . If you not read that post, you can read here to understand full concept of this fast calculation methods . In this post, I will demonstrate How to multiply with base of hundred within 15 secs? As I already explained the concept of Vedic Multiplication in my previous post. Now, I will show the examples with little description. But you will be able to understand. So, Lets start with the first example: How to Multiply with Base of 100 Example 1. Multiply 78 by 96 Step 1. Well, here base is hundred, Put the two numbers 78 and 96 above and below on the left-hand side. Step 2. For the right-hand-side , find out Deviation of both numbers. That is, 78-100 = -22 and 96-100 = –04 , Write Numbers as shown below: Step 3. Now, for the right-hand-side of answer multiply the deviations 22 and 04, you will get 88, that is right
