In order to use this box method you must first start with 500 and find out what the smallest number is that goes into it. That smallest number is 2, and then you move 250 under the 500 because 250x2=500. and then you keep repeating this process until you get the number 1 at the bottom. Then the rest of what you need to know is written under the problem in the picture below. Now you might be thinking that this problem would be much easier to solve with a calculator. However, with a calculator you get a decimal (22.36) which is not specific enough. But, a calculator is good to use when you get an even number. For example, the square root of 25 is 5.
