OpenStudy (goldphenoix):

Writing a number to show the value of each digit. It is shown as a sum of each digit multiplied by its matching place value (units, tens, hundreds, etc.) - Mathisfun.

OpenStudy (jasmineflvs):

yup do that

OpenStudy (jasmineflvs):

like 127,980 would be 100,000+20,000+7,000+900+80

OpenStudy (goldphenoix):

So the 6 in the ten million would be written as 60,000,000 +

OpenStudy (goldphenoix):

What about the 4 in the millions digit? How would it be written as?

OpenStudy (anonymous):

4,000,000

OpenStudy (goldphenoix):

Good job! So you have 60,000,000 + 4,000,000 + What about the 1 in the hundred thousands place?

OpenStudy (jasmineflvs):

OpenStudy (anonymous):

+ 80,000 + 6,000 + 300

OpenStudy (jasmineflvs):

great job jen!!

OpenStudy (goldphenoix):

Yes. So in expanded form, it would look like: 60,000,000 + 4,000,000 + 100,000 + + 80,000 + 6,000 + 300.
