Editorial Integrity
Editorial Standards & Guidelines
Ensuring mathematical correctness, pedagogical clarity, and rigorous cross-examination against state and national curricula.
1. Content Authorship and Review
All worked exemplars, theoretical foundations, and Casio hardware keystroke sequences published on Biggan.me are drafted by STEM educators and engineering graduates. We do not generate unverified computational text or black-box calculations.
2. Verification Protocols
Every calculator module undergoes dual verification:
- Algorithmic Validation: Code undergoes continuous automated integration testing against edge cases and reference textbooks.
- Physical Hardware Verification: Exact button press sequences are executed on genuine Casio hardware (fx-991CW, fx-991EX, fx-991ES PLUS, fx-100MS) to ensure 100% exam-hall replication accuracy.
3. Correction & Transparency Policy
We treat educational accuracy with paramount importance. If an educator, student, or researcher spots an inaccuracy, our editorial desk reviews the submission within 48 hours and documents any amendments in the release log.
