Introductory lesson Mathematics Tricks and Fun

Hello, children and and friends, today while launching this -new YouTube channel" Mathematics tricks and fun " I offer my obeissance to that great mathematician -The Mother Nature.

I am Prema BSejekan, a retired medical professional I love mathematics and I pursued the passion for it ever since my childhood. It got ignited recently,when my elder sister gifted to me a book "Lilavati by 

Bhaskaracharya 2".After that I started collecting books on Vedic Mathematics by several authors. Among these the book by JagathGuru Swami Bharathi Krishna Theertha Maharaj is really an asset to my collection, some chapters of which I still I have to digest. 

Without wasting time, I will dive deep and come out with some magical pearls for you .

Now how much is (9999999999)2 don't panic the answer is 9999999998000000001 . what is the answer for 99999999*99999 = 9999899900001

Interesting,isn't it ? There are patterns like these arising from arithmatic progression, geometric progression, whorled pattern, fractal patterns etc.These patterns are seen in natural phenomenon as well.

 Give me the answer to 1 2 3 4 5 6 7 9 x 9.The answer is 111111111. Another example similar to this is 1 2 3 4 5 6 7 9 x 81 = 999999999

How quickly can you multiply 123456789x999999999.It is not difficult. The answer is 123456788876543211.

    Now I am going to arithmetic progression.I will teach all these, one by one in detail later . Can you square(2222222222)2 fast. The answer is4938271603950617284 Yet another example is (7777777777)2 =60493827148395061729.Isn't it fascinating? When your calculator fails, you will be able to do manually.The will and practice is needed in any field to become masters.Perdistence and perseverance always helps to achieve goals.

 Now the long multiplication example using Urdhwa Thiryagbhyam sutra we will see.87265x32117 = 2802690005.you can do squaring more easily of these numbers. (24856)2. =604471396. 

Conversion of fractions to decimals is very easy using Vedic mathematics. One example I will give here.

1/19 = .052631578947368421. I will teach all these in the coming videos.

Maths is to be appreciated and enjoyed.It is there everywhere. In the movement of ants, the migration of birds,inthe arrangement of petals in flowers,and of leaves,Fibonacci sequence seen evidently in purple cabbage,in the sinuous curves of a moving snake,in the spiralling of snail shell,in the trees, in the flow of the river,in the mountains, in the sand dunes, in the clouds,in the outer space ,even in you and me.

Because of its play in the reduction division of chromosomes to 22X or 22Y,and its fusion, multiplication and exponential growth we are here bestowed with intelligence by complex calculations and yet failing to mimic and make artificial intelligence in its highest degree. Even in nature failures do occur.We call them as aberrations of nature. What does it teach us? Not to stop Reason it out why it occurs? And solve it. This is how maths improves our brain. It increases our patience ,reasoning , analytical skill and intuitive power. 

This is simply seen in the the continuous spinning of the yarn, in an effort to make the net, by the spider the smallest creature . So why not you? ask the nature .

Let us start understanding mathematics step by step without fear and boredom,learning from each other and nature.Subscribe to my channel and ring the bell icon for notifications. I will be uploading the videos twice a week.Small concepts you can learn and surprise others ,thus making it thorough .When you share with others ,you learn more. Thank you.
