This talks about Project Euler's problem #1, with a bonus challenge from Gauss.

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

-=EXAMPLE=-
"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..." -PE

Thanks to Scratch, Project Euler, Wikimedia, MIT's Learning Creative Learning, and you for making this planet a better place.

Thanks to Leonhard Euler and Carl Friedrich Gauss for their invaluable contributions to the world and their "swift" ways of thinking about maths.

-=KEEP SCROLLING=-

-=MINI SPOILER=-
Multiples of 3 - 3, 6, 9
Multiples of 5 - 5

Sum of 3, 5, 6, and 9 = 23

That was easy, you may have figured it out before reading this spoiler and may have even done it all in your head. But what about all multiples of 3 or 5 from 1 to 999?

(hint: not 3 or 5 or 15, just 3 or 5)

I think we'll need a faster way than counting them all up manually.

Think you have what it takes? Try Project Euler's problem #1 and see if you can code up your own solution in Scratch or another programming language! You can check to see if you get the answer right at Project Euler!
