In his *Elem A lot of elementary mathematics involves converting from one form to another and back again. Sometimes these forms have important differences of use, e.g. factored form or completed square form for a quadratic. However, sometimes these equivalent forms are more customary than because it *"manifestly corresponds with the nature of the thing"* in question.
