Expanded form is just the place values added together.
Do you remember how to write a simple number in expanded form? For example, is written as:
thousands + hundreds + tens + ones
9,75,218 expanded in the three forms page 13 prints.
Problem. Write the 6-digit numeral in expanded form in three different ways.
One numeral in all three expansions, side by side.
Remember: Expanded form of a numeral is the sum of the place values of each digit of the numeral.
What about zero? A place holding a contributes to the sum. The book writes that in the sum to clearly show the place is kept. For example: .
Two items from Worksheet 6 with the boxes left blank.
Fill in the missing values to complete the word form of these expanded numbers.
(a) The expansion of is ten thousands + thousands + hundred + tens + ones.
(c) The expansion of the larger numeral is lakhs + ten thousands + thousands + hundreds + tens + ones.
The two Worksheet 6 items where a place holds nothing.
Let's see how to handle a in expanded form.
(d) For the numeral , we write the directly in the sum to show the ten thousands place is kept: + + + + + .
(e) Sometimes, zero terms are skipped completely depending on how it's written. For example, can be written simply as + + .
Going the other way: from a sum back to the numeral.
Given the expanded form of a number, we can easily run the process backwards to write the numeral in standard form.
The page 13 items with a zero term and a missing place.
Problem. Write the standard numeral for:
(c)
(d) .
