Agent. The galaxy's most advanced space station — NEXUS-7 — has been infiltrated by the Void Collective, a group of rogue AI robots who have locked every critical system behind fraction-based security vaults.

You have 35 minutes before the station's reactor overloads. You must crack through 7 security stages, each protected by fraction puzzles of increasing complexity. Each stage you clear will reveal a digit of the MASTER OVERRIDE CODE.

Work carefully. Work fast. The fate of NEXUS-7 — and everyone aboard — rests on your mathematical skills.

✔ Show all working in your mission log (exercise book)
✔ Answers may be fractions, whole numbers, or mixed numbers
✔ Ask your handler (teacher) for emergency support if stuck
