Contrast Adjustment: Press MODE repeatedly until "CONT" appears, then use the arrow keys to adjust screen visibility.
Clearing Memory: Use SHIFT then 9 (CLR) to reset setup, memory, or the entire system. Core Mathematical Functions
The fx-50FH II handles everything from basic arithmetic to calculus.
Fractions: Use the ab/c key to input fractions. Press SHIFT then ab/c to toggle between improper and mixed fractions.
Trigonometry: Ensure you are in the correct unit (Deg, Rad, or Gra) by checking the top of the screen. Change this in the setup menu.
Calculus: The ∫dx key allows for numerical integration, while d/dx handles differentiation at a specific point.
Coordinate Conversion: Easily switch between Polar (Pol) and Rectangular (Rec) coordinates using the dedicated function keys. Programming Features
What sets the fx-50FH II apart is its ability to store 4 programs with a total of 680 bytes of memory. Writing a Program Press MODE until you reach the PROG mode. Select Edit and choose a slot (P1, P2, P3, or P4). Input your formula or commands. Press AC to save. Running a Program
Simply press the Prog key followed by the number of the slot (1-4) you wish to execute. Using Built-in Formulas
The calculator comes pre-loaded with 23 built-in formulas, covering common physics and math scenarios. Accessing Formulas: Press the FMLA key. Navigation: Use the arrow keys to scroll through the list.
Execution: Once you find the formula (e.g., Quadratic Formula), press EXE and input the required variables when prompted. Statistics and Regression For data analysis, the STAT mode is essential.
Data Entry: Enter STAT mode and choose your type (SD for single variable, REG for paired variables). Use the M+ key to input data points.
Retrieving Results: Press SHIFT then 1 (S-SUM) for totals or SHIFT then 2 (S-VAR) for mean and standard deviation. Maintenance Tips
Battery: The fx-50FH II uses a Two-Way Power system (Solar + LR44 battery). Replace the battery if the display dims significantly.
Storage: Keep the protective hard case on when not in use to prevent screen scratches or key damage.
Resetting: If the calculator behaves erratically, use a thin object to press the RESET button on the back. The Casio fx-50FH II is an HKEAA-approved programmable

π Constant Correctly in ProgramsThe manual notes that π is stored as SHIFT + ×10^x. But in program mode, you must use SHIFT + EXP to get π—otherwise, you will get a syntax error. This is a common trap.
The Casio fx-50FH II is a "programmable calculator," but without the manual, the programming features are useless. Many students buy this calculator believing it will automatically solve calculus problems—it won’t. You must input the formulas yourself, using the precise syntax the manual teaches.
In the weeks leading up to your HKDSE Mathematics Paper 1 (compulsory part) and Paper 2 (multiple-choice), spend one evening reading the manual cover to cover. Pay special attention to:
a b/c vs. SHIFT + a b/c for improper fractions).Download the Casio fx-50FH II user manual today in PDF format and keep it on your phone. Search for the "HKEAA Approved Calculators" notice inside—it confirms you are using the correct model. With the manual as your guide, you can transform a simple plastic device into a personalized math assistant that saves minutes per question, reduces silly arithmetic errors, and gives you a genuine edge in the examination hall.
