Proportion/Many Forms

Stuff you need to know before starting:
Before starting with Anurupyena multiplication tricks , I recommend you to go through the 2.Vinculum Process and Nikhilam Sutra of Multiplication. This 2 techniques will help you to understand Anurupyena.
Specific Condition Required:
- Anurupyena sutra multiplication is used whenever both numbers are not closer to power of 10(10, 100, 1000, etc) and hence applying Nikhilam Method is not simple.
- But if numbers are closer to multiples of 10’s (i.e. closer to each other) and their difference are easy to multiply then we can apply this Anurupyena Technique.

Process:
- Working Base(W.B.) concept: If numbers are closer to 60, we take working base as 60 (10X6) instead of 100. Here factor is 6. If numbers are closer to 50, we can take working base as 50 (10X5) OR 50 (100/2), etc, here factors are 5 and 2 respectively
- Apply concept of Nikhilam as usual.
- Mutiply/divide by the SAME factor used in 1st step. i.e. W.B. is obtained by multiplication of factor then Mutiply else divide.

Ann says
Can you please tell me how to do 18*28 with this method.
Rahul Bhangale says
You can consider base as 20 = 10 x 2 … Now carry out like above examples.
Ann says
Rahul,
I am getting my answer wrong, could please help.
I get
18 -2
28 +8
—————-
26 -16
*2
——
52 -16
changing to normal,
52+1 / 84
53/84, carrying forward 8
614.
Rahul Bhangale says
Hello Ann,
After you get 52 -16,
You need to carry forward -1 to 52, so it becomes
51 -6 (This is Vinculum Number)
Converting to Normal Number, it gives
504.
