3. Nga Tohutohu Whakahaere
This section provides a guide to the various functions and operations of your Casio fx-300MS Plus 2nd Edition Scientific Calculator.
3.1 Tatau Taketake
Enter numbers using the numeric keypad and perform operations using the [+], [-], [×], a [÷] patene. Perehi [=] hei whakaatu i te hua.
3.2 Ngā Mahi Pūtaiao
The calculator offers a wide array of scientific functions. Many functions are accessed by pressing the [SHIFT] key followed by the desired function key (indicated in yellow above the keys).
- Taumahinga Trigonometric: Whakamahi hara, [ko], [pango] for sine, cosine, and tangent. Inverse functions (sin⁻¹, cos⁻¹, tan⁻¹) are accessed via [SHIFT].
- Ngā Kōarotāma: Whakamahi [rārangi] for base-10 logarithm and [ln] mō te logarithm tūturu.
- Ngā Mana me ngā Pūtake: Whakamahi [x²] for square, [√] for square root, [x³] for cube, and [³√] for cube root. General powers ([^]) and roots ([SHIFT] [^]) are also available.
- Ngā Whakatauranga: Whakamahi [x!] (i uru atu mā [SHIFT]) for factorial calculations.
3.3 Fraction Calculations
The dedicated fraction key [a b/c] allows for easy entry and calculation of fractions and mixed numbers. Use [SHIFT] [a b/c] to convert between improper fractions, mixed numbers, and decimal equivalents.
3.4 Ngā Tātaitanga Tatauranga
To enter Statistics Mode, press [MODE] and select the appropriate statistical option (e.g., SD for standard deviation, REG for regression). Follow the on-screen prompts to input data and perform calculations.
3.5 Variable Memory
The calculator can store up to 9 variables (A-F, X, Y, M). To store a value, enter the number, press [STO], and then press the alpha key corresponding to the desired variable (e.g., [ALPHA] [A]). To recall a value, press [RCL] and the variable key.



3.6 Ngā Aratau me ngā Tautuhinga
Pehia te [MODE] button to cycle through different calculation modes (e.g., COMP for basic arithmetic, STAT for statistics). The [SETUP] button (accessed via [SHIFT] [MODE]) allows you to configure display settings, angle units (degrees, radians, grads), and number formats.
3.7 Whakaweto
Hei whakaweto i te tātaitai, pēhia [SHIFT] whai muri [AC] (WATA).

4. Tiaki
4.1 Te horoi
To clean the calculator, use a soft, dry cloth. For stubborn dirt, lightly dampen the cloth with water and a mild detergent, then wipe dry. Avoid using strong solvents or abrasive cleaners, as these can damage the calculator's surface or display.
4.2 Rokiroki
When not in use, store the calculator in its protective hard case to prevent scratches and damage. Keep it away from extreme temperatures, humidity, and direct sunlight. The solar panel requires light to function, but prolonged exposure to intense heat can be detrimental.
4.3 Whakakapinga Pūhiko
If the display becomes dim or calculations are slow, even in good lighting, it may be time to replace the LR44 backup battery. Refer to section 2.1 for battery installation instructions.
5. Te Raru
- He waatea te whakaaturanga: Ensure the calculator is in sufficient light for the solar panel. If it remains blank, replace the LR44 backup battery.
- Ngā hua hē: Check the current mode (e.g., degrees vs. radians for trigonometric functions). Press [SHIFT] [MODE] to access setup and adjust settings. Ensure correct input of numbers and operations.
- Calculator freezes: Pehia te [AC] button to clear the current calculation. If the issue persists, try removing and reinserting the battery to perform a hard reset.
- Ko nga paatene kaore i te aro: Ensure no debris is lodged under the keys. Clean the calculator as described in section 4.1.
