To round a number to the nearest hundred, you first take only digits that are place value hundreds and greater. In this case, we have 500. The next step is to look at the 10s place to see if we need to round up or not. If the tens place is a 5,6,7,8 or 9 we round up. Otherwise, we don't. In this case, it is a 2, so we leave it as it is. Thus, 523 rounded to the nearest hundred is 500.
