<mn>

The MathML <mn> element represents a numeric literal which is normally a sequence of digits with a possible separator (a dot or a comma). However,  it is also allowed to have arbitrary text in it which is actually a numeric quantity, for example "eleven".

mathvariant

This attribute specifies the logical class of the number which varies in typography.

The following values are allowed:

• normal (Default value) ; $\mathrm{Example}$
• bold ; $\mathbf{Example}$
• italic ; $\mathit{Example}$
• bold-italic ; $\mathit{Example}$

• double-struck ; $\mathbb{Example}$
• bold-fraktur ; $\mathfrak{Example}$
• script ; $\mathcal{Example}$
• bold-script ; $\mathcal{Example}$
• fraktur ; $\mathfrak{Example}$

• sans-serif ; $\mathsf{Example}$
• bold-sans-serif ; $\mathsf{Example}$
• sans-serif-italic ; $\mathsf{Example}$
