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.
2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder.

Each new term in the Fibonacci sequence
is generated by adding the previous two terms.
By starting with 1 and 2, the first 10 terms will be:
1, 2, 3, 5, 8, 13, 21, 34, 55, 89, …
Find the sum of all the even-valued
terms in the sequence which do not exceed one million.
If we list all the natural numbers below
10 that are multiples of 3 or 5, we get 3, 5,
6 and 9. The sum of these multiples is 23.
