Expanded Form
If we arrange 24568 in the place value chart, we see that the numeral contains
24 thousands, 5 hundreds, 6 tens and 8 ones.
Therefore, it can also be written as 20000 + 4000 + 500 + 60 + 8.
A number can be expressed in expanded form in any of the given three
methods :
« 24568 = 2 ten thousands + 4 thousands + 5 hundreds + 6 tens + 8 ones
« 24568 = 2 × 10000 + 4 × 1000 + 5 × 100 + 6 × 10 + 8
« 24568 = 20000 + 4000 + 500 + 60 + 8
Example : Write the following numbers in expanded form.
a. 23456 b. 35463
Solution :
a. 23456 = 2 ten thousands + 3 thousands + 4 hundreds + 5 tens + 6 ones
Or
(2 × 10000) + (3 × 1000) + (4 × 100) + (5 × 10) + 6
Or
20000 + 3000 + 400 + 50 + 6
