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.

Find the sum of all the multiples of 3 or 5 below 1000.

It has always been fun for me to play with mathematic prob...

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, ...`

By considering the terms in the Fibonacci sequence whose v...

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

What is the smallest positive number that is evenly divisible by all of the numbers from 1 to 20?

**This is the fastest and shortest...

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

`1^2 + 2^2 + ... + 10^2 = 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...
