The question

Question: what number is 200 + 7?

200 + 7

1 Put each part in the chart

Here is a place-value chart.

200 is 2 hundreds.

The 2 goes in the hundreds.

7 is 7 ones.

The 7 goes in the ones.

There are no tens.

We write 0 in the tens.

2 Read the number

So the number is 207.

= 207

Careful!

Without the 0, the digits move to the wrong places.

The 0 holds the tens place.

Careful: not 27 ✗

3 Check

We split it again: 207 is 200 and 7.

Yes!

It works.

207 = 200 + 7

Let's look back.

First: put each part in the chart.

Then: read the number.

Last: check.

Answer
= 207
