Either use this or remove it.

You can also just omit "values" above.
sub(Vector<CSSNumberish>&&)

inconsistent spacing.

remove

This is probably also good to have above.

> +    Ref<CSSNumericValue> add(Vector<CSSNumberish>&& values);

"values" is probably unnecessary here.  It doesn't add any meaning.

> Source/WebCore/css/typedom/numeric/CSSMathMax.cpp:50
> +const CSSNumericArray& CSSMathMax::values()

const after values()
and in header.

> Source/WebCore/css/typedom/numeric/CSSMathOperator.h:32
> +enum class CSSMathOperator: uint8_t {

nit: space before colon

> Source/WebCore/css/typedom/numeric/CSSMathSum.cpp:50
> +const CSSNumericArray& CSSMathSum::values()

const after values()

> Source/WebCore/css/typedom/numeric/CSSMathValue.h:36
> +enum class CSSMathValueType: uint8_t {

space before colon.

> Source/WebCore/css/typedom/numeric/CSSNumericBaseType.cpp:28
> +#if ENABLE(CSS_TYPED_OM)

You should probably just omit this file, unless you have plans for it.
If you do need it, you need to include config.h and CSSNumericBaseType.h outside the ENABLE macro.

> Source/WebCore/css/typedom/numeric/CSSNumericBaseType.h:32
> +enum class CSSNumericBaseType {

: uint8_t

> Source/WebCore/css/typedom/numeric/CSSNumericType.cpp:31
> +#if ENABLE(CSS_TYPED_OM)
> +
> +#include "config.h"
> +#include "CSSNumericType.h"

include outside the ENABLE macros.

Omit this file.

This really needs bounds checks.  I'm not sure what to return if it's out of bounds.

Omit this file.

This pattern can be replaced by one of two things to become more efficient:
1. WTF::map
2. Something like this:
Vector<Ref> values;
values.reserveInitialCapacity(numberishes.size());
for (auto&& numbers : numberishes)
    values.uncheckedAppend(...)

Currently, each append needs to check the capacity of the Vector which adds unnecessary branches, and if there is a large number of numberishes then we will reallocate and copy several times.  Using these patterns makes it so there is 1 allocation and 0 capacity checks.
