Display and Direct Algebraic Logic (D.A.L.)

The calculator features a 2-line LCD display, showing both the calculation entry and the result simultaneously. The Direct Algebraic Logic (D.A.L.) system allows you to input elements of an expression in the exact order they appear when written, simplifying complex calculations.

Aiki na asali

• Addition, Subtraction, Multiplication, Division: Enter numbers and use the +, -, ×, ÷ makullai. Latsa = for the result.
• Share Shigarwa/A share duk: Latsa ON/C once to clear the current entry. Press it twice to clear all calculations and memory (except independent memory).

Scientific Functions (273 Functions)

The calculator supports a wide range of scientific functions. Many keys have secondary functions, accessed by pressing the Na biyu F maɓalli da farko, sannan maɓallin aiki da ake so.

• Ayyukan Trigonometric: zunubi, cos, tan da ayyukansu sabanin (arc sin, arc cos, arc tan).
• Ayyukan Logarithmic: log (logarithm na gama gari), ln (natural logarithm).
• Iko da Tushe: x², √, yˣ.
• Factorials: n!
• Reciprocals: 1/x ku
• Hyperbolic Functions: hyp (hyperbolic sine, cosine, tangent).

Ayyukan Ƙwaƙwalwa

The calculator includes eight temporary memories, one independent memory (M+, M-, RCL M), and one last answer memory (ANS).

• STO (Store): Stores a value into a variable (A-F, X, Y).
• RCL (Recall): Recalls a value from a variable.
• M+/M-: Adds/subtracts the displayed value to/from the independent memory.
• ANS: Recalls the result of the previous calculation.

Statistical Functions

The calculator supports 1-variable and 2-variable statistics, along with six regression types.

1. Latsa MODE don zaɓar STAT yanayin.
2. Choose the desired statistical calculation type (e.g., 1-VAR, 2-VAR).
3. Enter data using the CD ɗin DATA key.
4. Perform calculations using the statistical function keys.

N-Base Calculations

Perform calculations in Hexadecimal (HEX), Binary (BIN), Decimal (DEC), Octal (OCT), and Pentadecimal (Alƙalami) bases.

• Use the dedicated keys for base conversions (e.g., → HEX, →BIN).
• Logical operations like AND, OR, NOT, XOR, and XNOR are also available.

Equation Editing & Playback

The calculator allows for editing previously entered equations and multi-line playback. Use the arrow keys to navigate through entries and make corrections.

Maɓallin Gida

The GIDA key allows users to return to the initial calculation screen, clearing any previously entered data or settings without turning off the calculator.

Tsaftacewa

To clean the calculator, use a soft, dry cloth. Do not use abrasive cleaners, solvents, or spray directly onto the calculator. Avoid excessive moisture.

Protective Hard Cover

The calculator comes with a protective hard cover. Always use this cover when the calculator is not in use to prevent scratches, dust accumulation, and accidental damage to the display and keys.

Tushen wutar lantarki

The EL-531TGBBW utilizes Twin Power, meaning it operates on both solar energy and a AAA battery. Ensure the solar panel is exposed to light for optimal performance and to extend battery life. Replace the AAA battery when the display becomes dim or unresponsive in low light conditions.

Shirya matsala

• Nuni ba komai bane ko duhu: Check battery installation and ensure sufficient light for the solar panel. Replace the AAA battery if necessary.
• Sakamakon lissafi mara daidai: Verify the input sequence and selected mode (e.g., DEG/RAD/GRAD, Normal/STAT). Press Sake saitin (located on the back, may require a thin object like a paperclip) to return the calculator to its default settings. Note that resetting will clear all memory contents.
• Kalkuleta ba ya amsawa ga maɓallan latsawa: Ensure the calculator is turned on. If it remains unresponsive, try removing and reinserting the battery, or perform a reset.
