Problem 6

The sum of the squares of the first ten natural numbers is,

12 + 22 + ... + 102 = 385

The square of the sum of the first ten natural numbers is,

(1 + 2 + ... + 10)2 = 552 = 3025

Hence the difference between the sum of the squares of the first ten natural numbers and the square of the sum is 3025 385 = 2640.

Find the difference between the sum of the squares of the first one hundred natural numbers and the square of the sum.


maxNumber = 100

sum = 0
sumOfSquares = 0

For i = 1 To maxNumber
  sum = sum + i
  sumOfSquares = sumOfSquares + i * i
EndFor

squareOfSums = sum * sum
difference = squareOfSums - sumOfSquares

TextWindow.WriteLine("Difference = " + difference)
