Hi, I have a decreasing while loop to which I have to add 3 each time I show an even number, but I can not get it added to me. What am I doing wrong?
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">

</head>
<body>
<script type="text/javascript">
var num = 100;
while(num >= 50){
document.write("Numero: " + num + "<br>");
if(num%2==0){
num + 3;
}
num--;
}
</script>
</body>
</html>
