Assuming you know that your number is a perfect square, the square root of an even number is even, and the square root of an odd number is odd.

All odd numbers are of the form 2n + 1, where n is an integer.So an odd number minus an odd number is (2n+1) - (2m+1) = 2n -2m = 2(n-m). Both n and m are integers, so while we don't know whether n-m is odd or even, we definitely know that it's an integer and that multiplying it by two cannot possibly give an odd number. So an odd number minus an odd number is an even number. For similar reasons, an odd number plus an odd number is also an even number.

An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. 467 is an odd number.
