Exact math stays live
Change one coefficient and watch factors, derivatives, roots, and exact mathematical evidence update together.
Read transcript
- Exact algebra can stay live inside an ordinary model.
- With plus two x, this perfect square has one double root.
- In Grid's Author view, change plus two x to minus two x.
- Factors, derivative, and root recompute exactly, not as rounded text.
- The new certificate fingerprint is the evidence trail for that result.
- Edit the term. Keep the proof.
