Arithym eliminates LLM math hallucinations and reduces wasted tokens on throwaway code generation. Instead of letting your model predict what math looks like, Arithym provides exact fraction arithmetic through a single MCP tool call — no code generation, no rework.
209 methods across 22 domains: basic arithmetic, algebra, statistics, trigonometry, unit conversions, combinatorics, number theory, and system modeling. Every result is exact — fractions stay as fractions through entire computation chains with zero floating-point drift.
Includes a curated reference knowledge layer with physics constants (NIST-sourced), periodic table data, unit conversion factors, and exact trigonometric values for common angles — all queryable as part of the math pipeline.
