2.1 Fa'apipi'i ma'a
The Sharp EL-531TH calculator requires one AAA battery for operation. A battery is typically included with the product.
- Saili le ufi o le vaega o le maa i tua o le calculator.
- Faase'e ese le ufi i le itu o lo'o fa'aalia e le aū.
- Insert one AAA battery, ensuring the correct polarity (+/-) as marked inside the compartment.
- Toe fa'apipi'i le ufi o le vaega o le maa se'ia kiliki ma le mautu i lona nofoaga.
2.2 Malosiaga Muamua i luga
A maeʻa ona faʻapipiʻi le maa, oomi le ON/C key to turn on the calculator. The display should show "0" or a similar initial state. If the display does not appear, recheck the battery installation or replace the battery.

3. Fa'atonuga o Galuega
3.1 Fuafuaga Fa'avae
Enter numbers using the numeric keypad and perform operations using the +, -, ×, ÷ keys. Press = ia maua le iʻuga.
Example: To calculate 15 + 7:
- Tusitala 1 5
- Tusitala +
- Tusitala 7
- Tusitala = (Result: 22)
3.2 Direct Algebraic Logic (D.A.L.)
The D.A.L. system allows you to input equations exactly as they are written. For example, to calculate sin(30):
- Ensure the calculator is in DEG (degrees) mode. (Press TULAGA then select DEG if needed).
- Tusitala agasala
- Tusitala 3 0
- Tusitala = (Result: 0.5)
3.3 Ki Galuega
Many keys have secondary functions, accessed by pressing the 2nd F key first. The secondary functions are typically printed above the primary key function.
Example: To calculate x² (square of a number):
- Enter the number, e.g., 5
- Tusitala x² (Result: 25)
Example: To calculate √x (square root of a number):
- Tusitala √
- Enter the number, e.g., 2 5
- Tusitala = (Result: 5)
3.4 Galuega Tau Manatua
The calculator includes memory functions to store and recall values.
- STO: Stores the displayed value into a memory variable (A-F, X, Y, M).
- RCL: Recalls a value from a memory variable.
- M+: Adds the displayed value to the independent memory.
- M-CLR: Clears the independent memory.
