Hey there~

I just logged each iteration to the console, here's how you're ending up at 55:

 Total of 0 + Count of 1 = 
1
 Total of 1 + Count of 2 = 
3
 Total of 3 + Count of 3 = 
6
 Total of 6 + Count of 4 = 
10
 Total of 10 + Count of 5 = 
15
 Total of 15 + Count of 6 = 
21
 Total of 21 + Count of 7 = 
28
 Total of 28 + Count of 8 = 
36
 Total of 36 + Count of 9 = 
45
 Total of 45 + Count of 10 = 
55

Here's how I logged it:

let total = 0 
let count = 1;
while (count <= 10) {
  console.log(`Total of ${total} + Count of ${count} =`);
  total += count;
  console.log(total);
  count++;
}
alert(total);

Hope this helps!
