3 The expanded form is a way of expressing the value of each number on its place value. Understanding large numbers becomes easier when the number is expressed in expanded form. The expanded form helps us to know the building blocks of higher numbers. Let us now see more about expanded form in the following topic.

7 Expanded form is a method of separating<a>numbers</a>or<a>expressions</a>into their parts. It involves expressing an algebraic statement as the<a>sum</a>of its<a>terms</a>in an expression or the place values in a number, and breaking down<a>decimal numbers</a>according to their place values.

8 The exact process of 'expanding' varies depending on whether<a>algebraic expressions</a>or numbers are involved. The following table shows the numbers and their expanded forms:

9 Number

10 Ten Thousand

11 Thousands

12 Hundreds

13 Tens

14 Ones

15 11

16 10 1253

17 200

18 50 39852

19 9000

20 800

21 50 254852

22 50000

23 4000

24 800

25 50 2<h2>What is the Place Value?</h2>

26 Place value shows the worth of a digit depending on its position in a number. It indicates how much each digit contributes to the total number. Each position in a multi-digit<a>integer</a>corresponds to a<a>power</a>of 10.

27 For example, the<a>place value</a>of the given digit 78,205 is:

28 7 is in the ten thousands place (70000)

29 8 is the thousands place (8000)

30 2 is in the hundreds place (200)

31 0 is the tens place (0)

32 5 is in the units place (5)

33 <h2>How to Write Numbers in Expanded Form?</h2>

34 To write numbers in expanded form, below-mentioned steps are followed -

35 Step 1:First write the number in<a>standard form</a>.

36 Step 2:Identify the place values for each digit.

37 For example, in the number 6,745

38 6 is in Thousands place (6000)

39 7 is in Hundreds place (700)

40 4 is tens place (40)

41 5 is in units place (5)

42 Step 3:Multiply the place values with their respective digits.

43 (6 × 1000), (7 × 100), (4 × 10), (5 × 1)

44 Step 4:Represent all the numbers as the sum of the<a>product</a>of the digit and their place value (digit × place value).

45 (6 × 1000) + (7 × 100) + (4 × 10) + (5 × 1)

46 Step 5: Represent the number in the Expanded Form.

47 The expanded form of 6,745 is 6000 + 700 + 40 + 5.
