3. بنيادي آپريشن
3.1. رياضي جا حساب
Perform basic arithmetic operations using the number keys and the +, -, ×، ۽ ÷ چاٻيون دٻايو = نتيجو ڏيکارڻ لاء.
- Exampاليزي: To calculate 15 + 7: Press 1 5 + 7 =. ڊسپلي ڏيکاريندو 22.
3.2. Clear Functions
- دٻايو CE to clear the last entered number or operation.
- دٻايو آن/سي to clear all entries and reset the calculator to its initial state (except memory).
4. سائنسي ڪم
The calculator provides 131 built-in functions. Many keys have secondary functions, accessed by pressing the ٻيو ايف key before the desired function key.
4.1. Trigonometric Functions
استعمال ڪريو گناهه, cos, رنگ for standard trigonometric calculations. Their inverse functions (گناهه-1, cos-1, رنگ-1) are accessed via ٻيو ايف.
The angle unit can be changed using the ڊي آر جي چاٻي دٻايو ڊي آر جي repeatedly to cycle through DEG (degrees), RAD (radians), and GRAD (gradients).
4.2. Logarithmic and Exponential Functions
- Logarithms: استعمال ڪريو لاگ (base 10) and ln (natural logarithm).
- Exponentials: استعمال ڪريو 10x (accessed via ٻيو ايف ۽ لاگ) ۽ ex (accessed via ٻيو ايف ۽ ln).
4.3. Powers and Roots
- چورس: استعمال ڪريو x2.
- چورس روٽ: استعمال ڪريو √ (accessed via ٻيو ايف ۽ x2).
- جنرل پاور: استعمال ڪريو yx.
- Reciprocal: استعمال ڪريو 1/x (accessed via ٻيو ايف ۽ yx).
4.4. Factorials
Calculate factorials using the n! function (accessed via ٻيو ايف ۽ سي پي ايل ايڪس).
5. ترقي يافته افعال
5.1. N-Base Calculations (HEX, DEC, BIN, OCT)
The calculator supports calculations in different number bases: hexadecimal (HEX), decimal (DEC), binary (BIN), and octal (OCT). Use the dedicated keys for these operations, typically found above the number keys (e.g., →OCT, →BIN, →DEC, →HEX).

5.2. Complex Number Calculations
To enter and perform calculations with complex numbers, switch to Complex Mode. Press سي پي ايل ايڪس to activate this mode. The display will show "CPLX".
Refer to the calculator's key markings for specific complex number operations (e.g., real and imaginary part extraction, argument, magnitude).
5.3. Statistics Functions
The calculator supports one-variable statistical calculations. To enter Statistics Mode, press اسٽيٽ. The display will show "STAT".
استعمال ڪريو DATA CD key to clear statistical data and the M+ key to input data points. Statistical results (mean, standard deviation, etc.) can be retrieved using specific function keys, often accessed via ٻيو ايف.
5.4. ياداشت جا ڪم
The calculator has one independent memory. Use the following keys:
- M+: Adds the displayed value to the memory.
- ايس ٽي او: Stores the displayed value into memory.
- آر سي ايل: Recalls the value from memory to the display.
6. سار سنڀال ۽ سنڀال
6.1. صفائي
To clean the calculator, wipe it with a soft, dry cloth. Do not use abrasive cleaners, solvents, or spray directly onto the calculator, as this may damage the casing يا اندروني جزا.
6.2. اسٽوريج
When not in use, store the calculator in its protective hardcover to prevent scratches and damage. Avoid exposing the calculator to extreme temperatures, humidity, or direct sunlight for extended periods.

7. مسئلا حل ڪرڻ
7.1. عام مسئلا
- ڪيلڪيوليٽر آن نٿو ٿئي: Check battery installation and ensure batteries are not depleted. Replace batteries if necessary.
- "Error" message displayed: This usually indicates an invalid operation (e.g., division by zero, taking the square root of a negative number). Press CE or آن/سي to clear the error and re-enter the calculation.
- Incorrect results: Verify that the correct mode (DEG/RAD/GRAD, Normal/Stat/Complex) is selected for your calculation. Ensure all previous calculations are cleared using آن/سي before starting a new one.
7.2. Resetting the Calculator
If the calculator behaves erratically or freezes, a reset may resolve the issue. Locate the ري سيٽ ڪريو button (a small recessed button, often requiring a thin object like a paperclip to press) on the back or front panel. Pressing this button will clear all memory and settings, returning the calculator to its factory default state.
