As a result of my daughter birthdates's inquiry, the five elements are short of "soil". I want to know whether this soil is supplemented in the name mathematics or in the three talents mathematics.

depends on pronunciation

not radicals

and the missing phase is based on the lunar month

There is no need to involve too much

The five-element arrangement of names should also consider

strokes

surnames

and of course the radicals involved in the zodiac

and so on

.
