Ranplase kouvèti lòj batri a epi an sekirite li ak vis la.

3.3 Premye pouvwa sou

Peze a ON/C button to turn on the calculator. The display will show the last calculation or be cleared, depending on the previous state.

4. Operasyon Enstriksyon

4.1 Kalkil debaz

Pou fè operasyon aritmetik debaz yo:

Antre premye nimewo a.
Peze bouton operasyon ou vle a (+, -, ×, ÷).
Antre dezyèm nimewo a.
Peze = pou montre rezilta a.

4.2 EkriView Ekspozisyon

Ekri aView ekspozisyon pèmèt ou antre ak view mathematical expressions as they appear in textbooks. Fractions, roots, and other complex expressions are displayed in a natural format. Use the navigation keys (up, down, left, right arrows) to move the cursor within an expression for editing.

4.3 Function Modes

The calculator offers various modes for different types of calculations. Press the MÒD key to cycle through available modes such as:

NORMAL: For general arithmetic and function calculations.
STAT: For statistical calculations.
EQN: For solving equations.

Refer to the on-screen indicators (e.g., DEG, RAD, GRAD) for the current angle unit. Press DRG► (accessed via 2yèm F) to change the angle unit.

4.4 Fonksyon Syantifik

The EL-W531 includes 335 functions. Many functions are accessed directly, while others require pressing the 2yèm F key first. Common functions include:

Trigonometric: sin, cos, tan, ak fonksyon envès yo (sin^-1, kos^-1, konsa^-1).
Logarithmic/Exponential: logaritm, ln, 10^x, e^x.
Power/Root: x², √, x^y, ^y√x.
Fraksyon: a b/c key for mixed numbers and improper fractions.
memwa: STO (store), RCL (recall), M+ (memory plus).

Consult the key labels and the calculator's display for specific function usage.

5. Antretyen

5.1 Netwayaj

Pou netwaye kalkilatris la, siye l dousman avèk yon twal mou epi sèk. Pa sèvi ak pwodui netwayaj abrazif, solvan, oswa twal mouye, paske sa yo ka domaje kalkilatris la.asing oswa konpozan entèn yo.
