Step by step
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
