2. Persediaan
2.1 Pemasangan Bateri
The Sharp EL-531TH calculator requires one AAA battery for operation. A battery is typically included with the product.
- Cari penutup petak bateri di bahagian belakang kalkulator.
- Luncurkan penutup mengikut arah yang ditunjukkan oleh anak panah.
- Insert one AAA battery, ensuring the correct polarity (+/-) as marked inside the compartment.
- Gantikan penutup petak bateri sehingga ia terkunci pada tempatnya.

3. Arahan Operasi
3.1 Pengiraan Asas
Enter numbers using the numeric keypad and perform operations using the +, -, ×, ÷ keys. Press = untuk mendapatkan hasilnya.
Example: To calculate 15 + 7:
- Tekan 1 5
- Tekan +
- Tekan 7
- Tekan = (Keputusan: 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 MODE then select DEG if needed).
- Tekan dosa
- Tekan 3 0
- Tekan = (Keputusan: 0.5)
3.3 Kekunci Fungsi
Many keys have secondary functions, accessed by pressing the Tingkat 2 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
- Tekan x² (Keputusan: 25)
Example: To calculate √x (square root of a number):
- Tekan √
- Enter the number, e.g., 2 5
- Tekan = (Keputusan: 5)
3.4 Fungsi Memori
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.
