00:01 Which of the following is correct name for the given number? we've got a massive big number here but it does not matter however big the number be there is a logic to writing this and once this logic is clear i think we can write out any big number as it gets now the logic is this if you have a very big number the first place would always correspond to the correspond to the once place then you have three zero so the second place would be the tenth place third place would be the thousand place and the next place and the next place and the next place and the next place next one would start as a thousand so a thousand would have three zeros a million would have six zeros as you can see a billion would have as many zeros as this so you for instance a billion would have three three six and nine so nine zero's so if you have a number let's say two and if you have let's say nine zeros one two three four five six seven eight nine so you can separate them by commas here so this that would be a two billion so likewise it's possible to see that a trillion would have a 12 trillion would have 12 zeros and then you have other higher order terms such as quadrillions quintillions etc so with respect to what the level of detail that is that we are look we will be looking at today is up to a trillion so i will look at how we can express this number suitably in a trillion form so the first thing that we need to do is write out the given number so let's write it down let's write the number down so let me move this a little bit this is just an example so let's write the given number so the given number is actually 8 zero six zero zero zero come a zero two zero and then we have zero zero zero and then we have another zero zero zero zero as you can see the first three places and right here so for instance if you look at the three zeros instead of if you had if you had three zeros which means you have let's say you have a number and followed by three zeros that would mean a thousand so up until this bit because there is no number existing in front we can call it this is the thousand this is the together with the number in front we can call it this is the thousandth place this would cover a thousand basically so the next bit is this bit that would cover a hundred thousand that would cover a hundred thousand so the next bit as you can see has six zeros one two three four five six now let's go back to this example let me rub this down because it's just for the sake of example so some number with the three with the with the with the six zeros would be represented as millions as we can see okay so that bit would cover another hundred million the next order is this here that would cover another hundred hundred but the order would be in billions the next order is another hundred but trillions so it's now clear that we've arranged them so this would be classified as eight hundred and six there are no numbers here so you would say eight hundred and six trillion twenty million that's it eight hundred and six trillion twenty million because there are no other numbers here so for example so as far as this problem is concerned, it's pretty clear that we can say this is 806 trillion and 20 million.
