EXPANDED FORM
A number written in the form of the sum of the place value of its digits is said
to be in its expanded form.
4
Let us write the expanded form of the number 356.
4 3 5 6
stands for 6 ones or 6
stands for 5 tens or 50
stands for 3 hundreds or 300
4
4
stands for thousands or 000

So, the expanded form of 356 is:
4
4 356 = thousands + 3 hundreds + 5 tens + 6 ones
= 4 000 + 300 + 50 + 6
17 Write the numbers in expanded notation. One has been done for you.
(a) 2376 = 2 thousands + 3 hundreds + 7 tens + 6 ones
(b) 4 618 = thousands + hundreds + ten + ones
4
(c) 51 9 = thousands + hundred + tens + ones
(d) 7961 = thousands + hundreds + tens + one
4
(e) 9 85 = thousands + hundreds + tens + ones
