Which computational limitation constrained early astrolabes from solving complex astronomical problems using algebraic methods?

💡 Explanation

When employing algebraic formulations on early astrolabes, calculation was geometrically represented as projections on the instrument's face; limited angular resolution from crude scale engraving then introduced cumulative approximation error for iterative algorithms. Therefore scale limitations degraded solution accuracy, instead of gear issues, abacus limitations irrelevant to the analog instrument, or lack of abstract methods like modern numerical iteration which are unrelated to the astrolabe itself.
