And, it’s complete! Oh! You’re back. I’ve missed you. So, what do you think of my new
collection of Numbers! Something is missing? That’s impossible. Everything’s here. There’s nothing missing. Oh, wait. Now I see. You are talking about the number
that denotes nothing. You are talking about the number Zero!
Right? So, let’s zero in! Oh, sorry. I mean, zooom in. Don’t you wonder why the number zero is
so important in mathematics? When it only means nothing? Well kids, it because of the two very
different and very important purposes.. ..that zero serves. Firstly, it’s Zero that separates the
negative numbers from the positives. Secondly, it serves as a place holder
for writing numbers. Consider the number 10 for example. It has two parts. 1 and 0. The number zero is placed here to say,.. ..that it is 10 times bigger than
the number 1! However, people from ancient times could
not wrap their heads around the idea.. ..of denoting nothing, by something. So, they never considered zero as a number. Consider this man, for example. Excuse me, Sir. Will you please tell me how many
sheep you have now? I don’t have even 1 sheep. You see, people were able to communicate
the idea of nothingness… Uh.. One minute, Sir. But they did not have a
representation for it. What is it? My sheep. Oh, yes of course. I’m sorry. Here you go. It was not until 628 AD.. ..that zero became an important part of the
number system, in East India. An Indian Astronomer and Mathematician,
Brahmagupta.. ..took the idea of nothingness… Symbolized it with a dot. And, included it in the number system. This was the first time in the whole world.. ..that zero was included in the number club. Hey, hold on. Wait a minute. Not so fast, with your celebrations
there, peeps. Although, Brahmagupta gave us the rules
for using zero in calculations.. ..defining it’s very first important use. He never introduced zero for
it’s second purpose. That is, as a place holder digit. It was another Indian mathematician,
Aryabhata. Who gave rules to use zero as a place holder. This helped representing numbers like 10,
with 1 and 0. Instead of coming up with a whole
new symbol for them. Thanks to these mathematicians for nothing! I mean zero. Soon this revolutionary knowledge spread
around the whole world. And, mathematicians across the globe started
using it in their calculations. Today, zero also forms an integral
part of Physics, Chemistry.. ..Astronomy and Computer Science too. Welcome, Welcome. We have been waiting for you all. Our family of numbers with the hero, Zero. So now, let’s look at some
of his properties. When the integers are placed
on a number line.. ..number 0 places itself before number 1. The number 0 is neither
negative nor positive. It’s a natural number. Come friends, let’s take this Zero back to
our number collection. Oh, look at this. Isn’t our Zero looking beautiful? What? No way. Something is missing again? 1..2..3..4… Oh! I see, I remember. TRIVIA TIME! There is a large number called Googol. That is written as 1 followed by
a hundred zeros. And do you know who coined it? Someone just like you. Googol. Milton Sirotta, the 9 year old nephew of
US mathematician Edward Kasner.. ..came up with the term Googol. That’s a lot of zeros, isn’t it? But wait till you hear about Googol Plex. Which is 1 followed by 1 googol zeros. Even Google could not have found me there. Wait. Doesn’t Google sound like Googol? It does! And that’s because the popular search engine
derived it’s name from the number Googol. And that my friend, is the story
of number zero. So kids, I hope you learnt something
interesting today. To know more about such cool inventions,
tune in next time. This is me zoooming out. Hey, kids. You liked my videos, didn’t you? Before you go, don’t forget to click on
