Math is always fun if you understand it. So, Today’s tutorial focusing on how to add series of Odd numbers easily.

Let us take a series of ODD Numbers from **1 to 100**

What do you think?. Going to take a calculator and add the odd numbers one by one?, Not at all!!

All you have do is just **find the number of ODD numbers from 1 to 100**, it’s pretty simple anybody can say **it’s 50!**

Now, Just **square** the number **50**

**50 x 50 = 2500 (Answer)**

So, the sum of ODD Numbers is **2500**, pretty simple right?

But, I think still you don’t believe what I said right?. No worries, now take a small series **1 to 20**

So, how many ODD numbers are there? It is **10** right?** **

**10 x 10 = 100 (Answer)**

Basically, 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 = **100**
