Answer:
680
Explanation:
An easy way to do this is to think of the number as in parts.
213 would be 200 + 10 + 3.
Whereas 467 would be 400 + 60 +7.
Now looking at these numbers, you can add the ones, tens and hundredths place together.
3 + 7 = 10
60 + 10 = 70
200 + 400 = 600
Now you have this equation:
600 + 70 + 10 = 680
The answer to 213 plus 467 would be 680.
