Mathematical Truth,
Not Statistical Probability.
Stop treating math as a language problem. QWED parses natural language into symbolic logic and executes it using a hardened SymPy kernel. It doesn't predict numbers; it solves for absolute truth.
Why do LLMs fail at math?
Large Language Models like GPT-4 and Claude are "Next Token Predictors." They don't actually perform calculation; they remember arithmetic patterns from their training data.
The Memorization Trap
An LLM knows that "2 + 2 =" is usually followed by "4". But ask it to calculate the cube root of 8,492, and it will confidently hallucinate a number that looks right but is mathematically wrong.
Floating Point Drift
Even when they try to calculate, LLMs often struggle with precision. A 0.01 deviation in a financial report or an engineering load calculation is catastrophic.
No Logic Constraints
LLMs lack an internal consistent world model. They can say "A > B" and "B > C" but then fail to conclude "A > C" in complex word problems.
How the Engine Works
A deterministic pipeline for absolute precision.
Intent Parsing
Extracts mathematical entities (numbers, units, operations) from natural language prompts.
AST Generation
Constructs an Abstract Syntax Tree representing the problem as pure logic, stripping away linguistic noise.
Symbolic Kernel
Executes the logic using SymPy (Python) or Z3. Solves integrals, derivatives, and equations algebraically.
Formatting
Converts the result back into human-readable text, JSON, or LaTeX for rendering.
The Liability Shield
In regulated industries, an AI hallucination is not just a bad answer. It can create legal, financial, and operational exposure. QWED adds verification checks and auditability before those results reach production workflows.
FinTech Compliance
Truth in Lending Act (TILA) requires 100% accurate APR disclosures. Relying on raw GPT-4 for loan estimates exposes you to massive regulatory fines.
EdTech Integrity
You cannot teach math with "approximate" answers. QWED ensures your AI tutor provides the correct steps and final solution, every time.
Engineering Safety
Validate unit conversions (e.g., PSI to Pascals) and load calculations. A decimal point error in structural engineering can be fatal.
