When we write a number as a sum of place value of its digits, the number is said to be in expended form and when we write a number using digits, the number is said to be in short form. There are 3 ways to write the expanded form. There are 3 ways to write the expanded form for a given number.
Examples on Expanded Form and Short Form of a Number:
1. Write the expanded form for 43,257.
Solution:
1^{st} way: 4 ten thousands + 3 thousands + 2 hundreds + 5 tens + 7 ones
2^{nd} way: 4 × 10000 + 3 × 1000 + 2 × 100 + 5 × 10 + 7 × 1
3^{rd} way: 40000 + 3000 + 200 + 50 + 7
2. Write the expanded form for 14,080.
Solution:
14,080 = 1 ten thousand + 4 thousands + 8 tens [Note: We do not write the place value for hundreds and ones as these places are filled with zero.]
or, 1 × 10000 + 4 × 1000 + 8 × 10
or, 10000 + 4000 + 80
3. Write the short form for the given expanded forms.
(i) 8 ten thousands + 6 hundreds + 6 tens + 3 ones
(ii) 9 × 10000 + 7 × 1000 + 4 × 10 + 2
(iii) 40000 + 3000 + 900 + 70 + 8
Solution:
Expanded Form (i) 8 ten thousands + 6 hundreds + 6 tens + 3 ones (ii) 9 × 10000 + 7 × 1000 + 4 × 10 + 2 (iii) 40000 + 3000 + 900 + 70 + 8
