Sum of the first 2010 square numbers

We define square numbers as numbers that when squared will equal a whole number. Thus, the list of the first square numbers starts with 1, 4, 9, 16, and so on.

What is the sum of the first 2010 square numbers, you ask? Here we will give you the formula to calculate the first 2010 square numbers and then we will show you how to calculate the first 2010 square numbers using the formula.

The formula to calculate the first n square numbers is displayed below:

		n(n + 1) × (2(n) + 1)
		6

To calculate the sum of the first 2010 square numbers, we enter n = 2010 into our formula to get this:

		2010(2010 + 1) × (2(2010) + 1)
		6

First, calculate each section of the numerator: 2010(2010 + 1) equals 4042110 and (2(2010) + 1) equals 4021. Therefore, the problem above becomes this:

		4042110 × 4021
		6

Next, we calculate 4042110 times 4021 which equals 16253324310. Now our problem looks like this:

		16253324310
		6

Finally, divide the numerator by the denominator to get our answer:

16253324310 ÷ 6 = 2708887385

There you go. The sum of the first 2010 square numbers is 2708887385.
