3. داخل کریں۔ 3, 0، پھر دبائیں =. ڈسپلے دکھائے گا۔ 0.5.

لکھیں۔View ڈسپلے

تحریرView feature allows you to input and display equations in a natural, textbook-like format.

• Enter equations as they appear in your textbook. The calculator will display fractions, roots, and other expressions clearly.
• Use the arrow keys (left, right, up, down) to navigate within an equation for editing.

Display Modes (DEG, RAD, GRAD)

The calculator supports three angle modes: Degrees (ڈی ای جیریڈینز (RAD)، اور گریڈیئنز (GRAD).

• To change the mode, press the موڈ key repeatedly until the desired mode (ڈی ای جی, RAD، یا GRAD) is highlighted or selected.
• The current angle mode is indicated on the display.

میموری کے افعال

The calculator includes memory functions to store and recall values.

• M+ (Memory Plus): Adds the displayed value to the independent memory.
• M- (Memory Minus): Subtracts the displayed value from the independent memory.
• آر سی ایل (Recall Memory): Recalls the value stored in the independent memory.
• ایس ٹی او (Store Memory): Stores the displayed value into a specific variable memory (A, B, C, D, E, F, X, Y, M).

Fractions and Decimals

• To enter a fraction, use the ab/c کلید
• To convert a fraction to a decimal or vice versa, press the دوسرا ایف کے بعد کلید ab/c کلید

شماریاتی افعال

The calculator includes various statistical functions.

• داخل ہونا اسٹیٹ موڈ، دبائیں موڈ کلید جب تک اسٹیٹ منتخب کیا جاتا ہے.
• Input data points and use the statistical function keys (e.g., mean, standard deviation) to perform calculations.
• Refer to the detailed function guide for specific statistical operations.

دیکھ بھال

Proper maintenance ensures the longevity and optimal performance of your calculator.

صفائی

• Wipe the calculator's exterior with a soft, dry cloth.
• Do not use abrasive cleaners, solvents, or wet cloths, as these can damage the casinجی یا اندرونی اجزاء۔
