The *Sutra* **“Puranapuranabhyam”** which means “By the Completion or Non-Completion” shows the ability of wholeness.

The representation of numbers from 1 to 10 in cyclic progression is called “Ten Point Circle”.

The important observation in the above “Ten-Point Circle” is that there are only five unique pairs of number that add up to 10.

**1 + 9 = 10**

**2 + 8 = 10 **

**3 + 7 = 10**

**4 + 6 = 10**

**5 + 5 = 10.**

Now the big question is – Why is “Ten-Point Circle” important? Why should we learn this?

Let’s understand this with an example:

**28 + 32**

The last digits above sum (8, 2) add to 10. So, whenever we see such pairs (which add to 10), there is no need to do manual addition.

It becomes very easy.

**28 + 32 = 60**

Let’s practice now:

**a.** 3 + 17 ** b. ** 6 + 24

**c. ** 8 + 32 **d. ** 47 + 3

**e. **55 + 5 **f. **9 + 61
