3. عملیاتي لارښوونې

3.1. بنسټیز عملیات

• بریښنا فعال/بند: مطبوعاتي ON/C د چالانولو لپاره. فشار ورکړئ دوهم ف بیا بند بندول
• د شمېرې داخلول: Use the numeric keys (0-9) and the decimal point key (.) to enter numbers.
• ریاضی عملیات: کارول +, -, ×, ÷ د اضافه کولو، کمولو، ضرب کولو او ویش لپاره. فشار ورکړئ = اجرا کول.
• پاکه ننوتنه: مطبوعاتي ON/C to clear the current entry.
• ړنګول: د کارولو DEL key to delete the last entered digit.

3.2. افعال

The EL-520TG features 419 functions, accessible directly or via the دوهم ف key for secondary functions printed above the keys.

• Direct Algebraic Logic (D.A.L.): Input calculations as they are written, following standard mathematical order of operations.
• مثلثیتیک دندې: کارول ګناه, cos, تان د ساین، کوزین او ټانجینټ لپاره. کارول دوهم ف بیا ګناه⁻¹, کاس⁻¹, ټان⁻¹ for inverse trigonometric functions.
• لوګاریتمیک دندې: کارول ننوتل for common logarithm (base 10) and ln for natural logarithm (base e).
• د حافظې دندې: The calculator has 9 memory registers. Use STO to store a value and RCL to recall a stored value.
• احصایوي دندې: د احصایوي طریقو ته لاسرسی ومومئ موډ. Calculate standard deviation and other statistical values.
• د ځواک او ریښې دندې: کارول x² for square, √ for square root, and yˣ for general powers.
