<h1>Multiples of 3 and 5</h1>
<h3>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.</h3>

JavaScript

var sum=0;

for(var i=0; i<1000; i++) {
    if(i%3===0 || i%5===0) {
        sum+=i;
    }
    console.log(sum);  //open the console to see the correct answer or just unmessage the alert below;
}
//alert(sum);  //233168 is the answer.
