The SAMS FX-991MS Scientific Calculator processes 401 mathematical functions on a high-resolution 2-line LCD. Twin power circuits use solar cells and LR44 batteries for continuous operation. This 2nd edition adopts a thinner profile and sleeker casing compared to the original SAMS FX-991MS 1st Edition.
Key Features
- 401 Integrated Functions: Supports matrix, vector, and complex number math. Handles complex engineering calculations without programmable memory.
- Dual Power Source: Combines solar panels with an LR44 battery. Maintains power during indoor use or sudden load shedding.
- 12-Month Warranty: Provides coverage for internal circuit failures. Validates hardware reliability over a one-year period.
- Equation Solver: Processes polynomial and linear equations for three unknowns. Accelerates algebraic problem-solving in high-pressure exams.
- 9 Variable Memories: Stores distinct values for quick recall across multiple steps. Reduces calculation errors during long mathematical proofs.
Frequently Asked Questions
Is SAMS FX-991MS allowed in board exams?
Non-programmable design follows most HSC and engineering exam board rules. It lacks data storage features that typically trigger exam bans.
How to solve equations in FX-991MS?
Access the 'EQN' mode to enter polynomial or linear variables. The screen displays roots and values for up to three unknowns.
