**Tell us what’s happen
Test case run failed.

Your code so far


<style type='text/sass'>
  $x: 1;
  @while $x < 11 {
    .text-#{$x} { font-size: 5px * $x;}
    $x: $x + 1;
  }
</style>

<p class="text-1">Hello</p>
<p class="text-2">Hello</p>
<p class="text-3">Hello</p>
<p class="text-4">Hello</p>
<p class="text-5">Hello</p>
<p class="text-6">Hello</p>
<p class="text-7">Hello</p>

5px is not a number, so you can’t multiply it.

You should be passing the test. Try a different browser I have seen people have some bugs with this challenge.

Number Operations
