I'm writing in a style somewhat following a Warring States to Han Dynasty text (the 九章算术). The problem isn't the concision per se, it's that that's just not what 术 means here; it's not something that takes arguments. I'm being slightly verbose but I can't think of a construction that doesn't involve 以 or 数 (or synonyms thereof). It's true you don't need both. Now there is a way to make your construction work with a wider context, for example in one where you've established 术 as the notion of a function. Your general impression is correct that earlier texts tend to get more concise and that Classical Chinese is quite grammatically flexible. But there's still limits. Moreover ancient mathematical texts tended to be far more explicit and written in a far more direct style. Ending particles such as 也 are actually fairly rare in such texts.
