Numbers have always existed. The same cannot be said of words. The latter are man made constructs and arbitrary. In Scientology literacy and superliteracy have been stressed and indeed clearing word definitions is of the utmost importance to achieve conceptual understanding.
But if numbers are eternal and even more basic as concepts compared to words it is paramount that students achieve a sufficient level of numeracy in that they at least study and understand basic numerical relationships and a study of enough mathematics will lead to what one might call supernumeracy.
