Re: Is the semantic tags example correct in https://www.w3.org/Math/whatIsMathML.html?

Shouldn't the first example on that page be formatted a little better? and
use the numeric entity instead of the named one?

<math xmlns="http://www.w3.org/1998/Math/MathML">
  <mrow>
    <mrow>
      <msup>
        <mi>x</mi>
        <mn>2</mn>
      </msup>
      <mo>+</mo>
      <mrow>
        <mn>4</mn>
        <mo>&#x2062;<!--INVISIBLE TIMES--></mo>
        <mi>x</mi>
      </mrow>
      <mo>+</mo>
      <mn>4</mn>
    </mrow>
    <mo>=</mo>
    <mn>0</mn>
  </mrow>
</math>
