Write 7,090 in expanded form

Step by step

The question

Question: write 7,090 in expanded form.

1 Put the digits in the chart

Each digit has a place.

2 Find the value of each digit

The 7 is 7 thousands.

That is 7,000.

The 9 is 9 tens.

That is 90.

The 0 means no hundreds.

We leave it out of the sum.

3 Write it as a sum

Expanded form means we write the value of each digit, with + between them.

4 Check

We add them back: 7,000 and 90 make 7,090.

Yes!

It works.

Let's look back.

First: put the digits in the chart.

Then: find the value of each digit.

Then: write it as a sum.

Last: check.
