2. የአሠራር መመሪያዎች

2.1 መሰረታዊ የሂሳብ ስራዎች

Perform basic calculations using the number keys and operation keys (+, -, ×, ÷). ተጫን = ውጤቱን ለማሳየት.

  • መደመር፡ 5 + 3 = (ውጤት፡ 8)
  • መቀነስ፡- 10 - 4 = (ውጤት፡ 6)
  • ማባዛት፡ 7 × 2 = (ውጤት፡ 14)
  • ክፍል፡ 15 ÷ 3 = (ውጤት፡ 5)

2.2 ሳይንሳዊ ተግባራት

The EL-W531TL offers over 420 scientific functions. Many functions are accessed by pressing the 2 ኛ ኤፍ ቁልፉን ተከትሎ የሚፈለገውን የተግባር ቁልፍ።

  • ትሪግኖሜትሪክ ተግባራት፡- ተጠቀም ኃጢአት, cos, ታን keys. For inverse functions, press 2 ኛ ኤፍ then the respective key (e.g., 2 ኛ ኤፍ ኃጢአት for sin-1).
  • ሎጋሪዝም ተጠቀም መዝገብ (መሰረት 10) እና ln (ተፈጥሯዊ ሎጋሪዝም) ቁልፎች።
  • ኃይል እና ሥሮች; ተጠቀም x² ስኩዌር ለማድረግ ፣ √ for square root. For other powers, use yx.
  • ክፍልፋዮች የሚለውን ተጠቀም ab/c key to enter and calculate fractions.

2.3 የማህደረ ትውስታ ተግባራት

The calculator includes independent memory (M) and variable memories (A-F, X, Y).

  • ወደ ማህደረ ትውስታ ያስቀምጡት፦ Enter a value, then press STO followed by the desired memory key (e.g., STO M+ to store to M).
  • ከማህደረ ትውስታ የተመለሰው፦ ተጫን አርሲኤል followed by the desired memory key.
  • ማህደረ ትውስታን አጽዳ; ተጫን M-CLR to clear all memories.

2.4 ሁነታ ምርጫ

የሚለውን ይጫኑ MODE key to cycle through different calculation modes (e.g., Normal, Stat, Drill). Press CA to change angle units (DEG, RAD, GRAD).
