To order a set of numbers from least to greatest,

compare each number to the other numbers in the set.

First, compare the digits in the hundreds place of each number.

2 is less than 6, so 256 and 265 are less than 652.

Next, compare the digits in the tens place of 256 and 265.

5 is less than 6, so 256 is less than 265.

256 is less than 265, which is less than 652.
