Good morning children now you know how to count till ten thousand let's learn more of counting which is the smallest single digit number which is the counting number it is 1 and which is the greatest single digit number it has to be 9 now let us set 1 to 9 what do we get it is equal to 10 so we get 10 which is the smallest two digit number now which is the greatest two digit number we can form it by using the greatest number or the greatest digit which is nine so for two digit use 9 two times we get 99 and what is 99 plus 1 it is equal to hundred so we get the smallest 1 2 3 3 digit number so 100 is the smallest 3 digit number if we keep going like this which is the greatest three digit number it has to be 3 times 9 written so 9 9 9 now again if we add 1 to it what should we get we should get the smallest four digit number let's add 9 plus 110 carry over 1 again 9 plus carry over 10 again 9 plus carry over 110 so we get 1,000 and as we said 1,000 is the smallest four-digit number continuing which is the greatest four-digit number it has to be nine nine nine nine four times nine written now add one to it what do we get we get 9 plus 1 10 0 here 1 goes above again 9 + 1 10 1 goes here again 10 1 goes here 10 so we get the smallest 5 digit number which is 10,000 so 10,000 is the smallest 5 digit number similarly the greatest five digit number should be 9 written 5 times so nine nine nine nine nine now let's again add 1 to it what do we get let's see nine nine nine nine nine which is exactly equal to 90 9999 if we add 1 to it what do we get 9 plus 1 is 10 carry over 1 now here adding 9 plus 1 again we get 10 so 0 1 is carry again 9 plus 1 is 10 0 here 1 is carry 9 + 1 10 0 here carry and lastly 9 + 1 it is equal to 10 now which is this number 1 2 3 4 5 6 it has six digit numbers it is the smallest 68 number and what do we call it one stands one hundred thousand ten thousand and one hundred thousand so this is equal to one hundred thousand and what is it called an Indian system it is the smallest six digit number see there are hundred thousands so one hundred thousand you know this one hundred thousand is the smallest six digit number which is equal to one hundred thousand and it is known as one lakh so remember children one lakh means one hundred thousand and it has one two three four five zeros to it and smallest six digit number understood so now you know what is one lakh it is nothing but it is equal to one hundred thousand is called one lakh so how do we get one lakh if we add one to ninety nine thousand nine hundred and ninety-nine we get 1 lakh or we can also do it other way if we multiply ten thousand by ten what do we get we get one hundred thousand and this is equal to one lakh so now you know what is 1 lakh equal to now let's try to add this is 1 lakh as it has five zeros to it plus 1 lakh if we add we get 2 lakhs so this is 2 lakhs - followed by five zeroes now let us see this is Munira and he bought huge land for rupees five seven six eight five zero how to read this it's little confusing is it five lakhs or fifty seven lakhs or fifty seven thousand so let us try to place the number under a place value chart and then it will be easy to read the number so this we have put five seven six eight five zero the number here and let's start putting the place value names so starting from the rightmost side once place tens place hundreds place thousands place next what will come ten thousands place and then what will come the hundred thousands place which is called lakh place so now it becomes very easy to read the number c5 is under lakh so it should be five lakh and seven is under ten thousand so seventy thousand and six is under thousand so six thousand and eight is under 100 its place so eight hundred five under tens place so fifty and zero is under ones place so zero only so what is it equal to we can say five lakh seventy six thousand eight hundred and fifty as there is no one's place here which is zero here specifically so it is not red so the number is five lag seventy six thousand eight hundred and fifty understood now let us try to put this number which is five lakh seventy six thousand eight hundred and fifty in expanded form so let's do it first starting from the lakhs 5 lakhs oh five x 1 lakh and we know there are five zeros in one lakh next coming here we know it is equal to what is it equal to it is ten thousands place so seven x now let us write this number in expanded form not that we have placed the number under the place value chart it becomes very easy so let's start from the lakh position so 5 into 1 lakh plus 7 into 10 thousand next 6 in two 1000 class what do we have 800 so 8 into 100 plus what do we
