Description:
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.
Finish the solution so that it returns the sum of all the multiples of 3 or 5 below the number passed in.
Additionally, if the number is negative, return 0.
Note: If the number is a multiple of both 3 and 5, only count it once.
