WHAT IS THE NEED FOR THE SYSTEM IN NUMBER SYSTEM? Welcome to my blog and thanks for your time today. Happy to inform everybody that I have been promoted to the middle grade. My math book has many chapters - Number System, Fractions, Decimals, Integers and so on. I am going to share some of the topics that I learnt in my MATH class.  My teacher started explaining about one of the concepts: What is the need for the system in Number System?  She started with this question and then continued: Numbers 0 to 9 followed by 10 , 11 , ------- Why all this?  We can write 1 as 01, 2 as 02, 9 as 09. The ones place has got all the numbers right from 0 till 9. Let us stop at 09. Now move towards getting the next number in the list.  After 9, we come back to 0 in the ones place. But the 0 in 09 is moved to the next number 1. Now we get the next number as 10. Now 1 is fixed at the leftmost place and 0 moves to 1 thereby giving us the next number 11. This goes on till we reach 19....
