But for that, it is important to understand the place value system. Now, that we have learnt how to decompose numbers from 1 to 100, we shall learn how to decompose larger numbers. Starting from 1 and by incrementing each number by 1, we can form the numbers from 1 10 100 as below – 1 Similarly, 5 = 1 + 1 + 1 + 1 + 1 = 1 + 3 + 1 = 2 + 3 = 1 + 4īased on above, we can thus learn how to decompose numbers from 1 to 100. There are three ways to compose the number 4. 3 can be decomposed by 1 + 1 + 1Īnother way to decompose 3 is by adding 1 to 2, i.e. Similarly, to decompose 3, we can add 1 to itself twice, i.e. To decompose 2 from 1 we have to add 1 to itself, i.e. This is the next counting number after 2.įrom the above, we can see that 1 is the first counting number. This is the next counting number after 1. How many balls can you see in the figure below? Let us learn about decomposing numbers from 1 to 5. The system that is used to represent and compose these numbers is called the number system. These digits, other than 0 are called counting numbers. There are 10 digits, a combination of which is used to compose different numbers. For example, we have the number “ Four “ which in numeric form is written as “ 4 “. So, how do we define a number? A number is an arithmetic value used for representing the quantity and used in making calculations. There are a different sets of numbers such as whole numbers, natural numbers and so on. But we don’t have just one set of numbers. Different arithmetic operations can be performed using these numbers. Without these numbers, it would be impossible to even count things. But, how do we compose these numbers? Let us find out. We are aware of different kinds of numbers that have been defined such as natural numbers, whole numbers, decimal numbers, fractions and so on. When we think of mathematics, the first thing that comes to our mind is numbers. How are Numbers placed in the Place Value System?.Importance of Place Value System in Composing Numbers.
