# Project Euler Problem 1: Multiples of 3 and 5¶

The source code for this problem can be found here.

## Problem Statement¶

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 $$1000$$.

## Solution Discussion¶

Nothing sophisticated here, explicitly perform the computation.

## Solution Implementation¶

def solve():
""" Compute the answer to Project Euler's problem #1 """
num_range = range(1, 1000)
valid = lambda n: n % 3 == 0 or n % 5 == 0  # number must be a multiple of 3 OR 5
numbers = [i for i in num_range if valid(i)]
